This document provides full guidance of Telink matter solution which
includes such to/uploads/zip/20230607200713DN6A9/pics as environment setup, Matter device firmware building
and flashing, Border Router setup including RCP building and flashing,
building and usage of chip-tool etc.
To avoid routine with Zephyr environment setup in section 3.2.1 and 3.2.3,
user can just pull and run existing docker image that contains ready to use
environment.
Run the Docker container (this will take a while to complete the first time):
For Matter v1.0-branch branch use the following line:
docker run -it --rm -v $PWD:/host -w /host connectedhomeip/chip-build-telink:$(wget -q -O - https://raw.githubusercontent.com/project-chip/connectedhomeip/v1.0-branch/.github/workflows/examples-telink.yaml 2> /dev/null | grep chip-build-telink | awk -F: '{print $NF}')
Docker image 'connectedhomeip/chip-build-telink:0.6.06'
For Matter master branch use the following line:
docker run -it --rm -v $PWD:/host -w /host connectedhomeip/chip-build-telink:$(wget -q -O - https://raw.githubusercontent.com/project-chip/connectedhomeip/master/.github/workflows/examples-telink.yaml 2> /dev/null | grep chip-build-telink | awk -F: '{print $NF}')
Docker image 'connectedhomeip/chip-build-telink:0.6.47'
Compatible docker image version can be found in next file:
.github/workflows/examples-telink.yaml
Setup dependencies:
In the new terminal go through Step 1 in
3.2.2 Matter project setup to setup dependencies.
Matter project:
In the Docker container go through Step 2-4 in
3.2.2 Matter project setup to clone Matter
repository into a clean folder, update submodules for Telink platform and run bootstrap.
Then, follow instruction in Chapter 4. Matter Firmware to build firmware.
Please execute APT update and upgrade before the following steps.
sudo apt update
sudo apt upgrade
Install dependencies:
wget https://apt.kitware.com/kitware-archive.sh
sudo bash kitware-archive.sh
sudo apt install --no-install-recommends git cmake ninja-build gperf \
ccache dfu-util device-tree-compiler \
python3-dev python3-pip python3-setuptools python3-tk python3-wheel xz-utils file \
make gcc gcc-multilib g++-multilib libsdl2-dev
Zephyr requires minimum version for main dependencies for now, such as
CMake (3.20.0), Python3 (3.6), Devicetree compiler (1.4.6).
cmake --version
python3 --version
dtc --version
Please verify versions installed on your system before next steps;
Otherwise please switch APT mirror to stable and latest one, or update
these dependencies manually.
Install west:
pip3 install --user -U west
echo 'export PATH=~/.local/bin:"$PATH"' >> ~/.bashrc
source ~/.bashrc
Make sure ~/.local/bin
is on $PATH
environment variable:
Get the Zephyr source code:
west init ~/zephyrproject
cd ~/zephyrproject
west update
west blobs fetch hal_telink
west zephyr-export
Command west blobs fetch hal_telink is needed only for Matter master branch.
It usually costs extra time to get the Zephyr source code using
west init ~/zephyrproject and west update within Chinese
mainland. Moreover, some project may fail to update from foreign
servers.
Please find alternative methods to download the latest source code.
Install additional Python dependencies for Zephyr:
pip3 install --user -r ~/zephyrproject/zephyr/scripts/requirements.txt
Setup toolchain:
Download Zephyr toolchain (about 1~2 GB) into local directory to allow
you to flash most boards.
It may take extra time within Chinese mainland.
For v1.0-branch used Zephyr SDK v0.13.2:
wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.13.2/zephyr-sdk-0.13.2-linux-x86_64-setup.run
chmod +x zephyr-sdk-0.13.2-linux-x86_64-setup.run
./zephyr-sdk-0.13.2-linux-x86_64-setup.run -- -d ~/.local/zephyr-sdk-0.13.2
For master used Zephyr SDK v0.15.2:
wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.15.2/zephyr-sdk-0.15.2_linux-x86_64.tar.gz
wget -O - https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.15.2/sha256.sum | shasum --check --ignore-missing
tar xvf zephyr-sdk-0.15.2_linux-x86_64.tar.gz
cd zephyr-sdk-0.15.2
./setup.sh -t riscv64-zephyr-elf -h -c
Download Zephyr SDK and install it in recommended path as below.
$HOME/zephyr-sdk[-x.y.z]
$HOME/.local/zephyr-sdk[-x.y.z]
$HOME/.local/opt/zephyr-sdk[-x.y.z]
$HOME/bin/zephyr-sdk[-x.y.z]
/opt/zephyr-sdk[-x.y.z]
/usr/zephyr-sdk[-x.y.z]
/usr/local/zephyr-sdk[-x.y.z]
Where [-x.y.z] is optional text, and can be any text, for example,
-0.13.2.
You cannot move the SDK directory after you have installed it.
Build Hello World Sample
Please verify the official Zephyr project configure is correct using
the Hello World sample before continue to set up custom project.
cd ~/zephyrproject/zephyr
west build -p auto -b tlsr9518adk80d samples/hello_world
Build the hello_world example with west build command from the root
of the Zephyr repository.
You can find firmware called zephyr.bin under build/zephyr
directory.
Add environment Zephyr script to ~/.bashrc
.
Here is the difference between prior added and added:
+ source ~/zephyrproject/zephyr/zephyr-env.sh
You can add the above line using editor such as vi/vim or execute the
following command in bash.
echo "source ~/zephyrproject/zephyr/zephyr-env.sh" >> ~/.bashrc
Execute the following line to active updated shell environment
immediately.
source ~/.bashrc
Add Telink Zephyr remote repository:
Download Telink repo to local as develop branch and update this
branch.
For Matter 1.0-release branch use telink_matter_v1.0-branch!
cd ~/zephyrproject/zephyr
git remote add telink https://github.com/telink-semi/zephyr
git fetch telink develop
git checkout develop
cd ..
west update
west blobs fetch hal_telink
Command west blobs fetch hal_telink is needed only for Matter master branch.
This update may cost extra time within Chinese mainland.
More info you could find here: https://docs.zephyrproject.org/latest/getting_started/index.html
Setup dependencies:
sudo apt-get install git gcc g++ pkg-config libssl-dev libdbus-1-dev \
libglib2.0-dev libavahi-client-dev ninja-build python3-venv python3-dev \
python3-pip unzip libgirepository1.0-dev libcairo2-dev libreadline-dev
Clone Matter project:
Clone Matter project to your local directory, e.g., /home/${YOUR_USERNAME}/workspace/matter.
git clone https://github.com/project-chip/connectedhomeip
This clone may cost extra time within Chinese mainland.
Update submodules:
Enter the repo root directory and Update submodule:
cd ./connectedhomeip
./scripts/checkout_submodules.py --platform telink
Do bootstrap:
Download and install packages into local for Matter. It usually takes
long time when we run it the first time.
source ./scripts/activate.sh
This step will generate an invisible folder called .environment
under the Matter root directory connectedhomeip.
It may cost extra time or encounter failure within Chinese mainland.
INFO: In case of any troubles with Matter build environment you may try:
Remove the environment (in root directory of Matter project):
rm -rf .environment
Redo bootstrap once again:
source ./scripts/activate.sh
Install ZAP CLI tool (only for master branch):
According to Matter documentation, ZAP is installed by bootstrap.sh script.
More info you could find here:
https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/BUILDING.md
Download toolchain:
Download and unzip Telink toolchain into your local directory, e.g. ~,
to allow you flash Zephyr into Telink board.
wget http://wiki.telink-semi.cn/tools_and_sdk/Tools/IDE/telink_riscv_linux_toolchain.zip
unzip telink_riscv_linux_toolchain.zip
You may spend several minutes on the download because this zipped file
is around hundreds MB.
The download may cost extra time outside Chinese mainland.
Setup dependencies:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install -y libc6:i386 libncurses5:i386 libstdc++6:i386
Run ICEman.sh script to change udev rules:
The following step 3 and 4 are set for flashing firmware to
developement boards on Ubuntu platform.
If you would like to flash firmware on Windows platform, please igonre
the following setup.
sudo sh ${TELINK_TOOLCHAIN_BASE_DIR}/ice/ICEman.sh
${TELINK_TOOLCHAIN_BASE_DIR}
is Telink SDK root directory, e.g.
~/telink_riscv_linux_toolchain
.
If you meet issues related to path or permissions, or disconnection
from your ubuntu host at current shell, you can enter the above
directory and then try to execute this script:
cd ${TELINK_TOOLCHAIN_BASE_DIR}/ice
source ICEman.sh
In ~/.bashrc
add SPI_burn and ICEman to PATH
.
Here is the difference between prior added and added:
+ export PATH=${TELINK_TOOLCHAIN_BASE_DIR}/flash/bin:"$PATH"
+ export PATH=${TELINK_TOOLCHAIN_BASE_DIR}/ice:"$PATH"
For Matter v1.0-branch branch:

Device-to-device communication without border router available in case if
one or several devices configured as FTD (Full Thread Device) for example
Light Bulb.
Application configuration file location (relative path):
examples/app/telink/prj.conf
MTD (Minimal Thread Device) configuration example:
# OpenThread configs
CONFIG_OPENTHREAD_MTD=y
FTD (Full Thread Device) configuration example:
# OpenThread configs
CONFIG_OPENTHREAD_MTD=n
Note: Option not set has the same effect
Low power configuration options:
Optional tuning:
The configuration option CONFIG_TELINK_BUTTON_MANAGER_IRQ_MODE requires reconnection of the buttons by the following schematic and requires the external buttons usage in case of using the TLSR9218ADK80d EVK:
Name | Pin |
---|---|
BUTTON_1 | PC2 (pin 16 of J20) |
BUTTON_2 | PC0 (pin 18 of J20) |
BUTTON_3 | PC3 (pin 20 of J20) |
BUTTON_4 | PC1 (pin 22 of J20) |
The second side buttons pins need to be connected together and connected to the GND. In case of using TLSR9218ADK80d EVK any GND pin on the back side of the board can be choosed.
This kind of connection pulls up the GPIO internally and the button event comes by FALLING EDGE on GPIO.
The current consumption with this configuration can be achieved as low as:
Setting max RF power configuration example:
# Custom RF power values
CONFIG_B91_BLE_CTRL_RF_POWER_P9P11DBM=y
CONFIG_OPENTHREAD_DEFAULT_TX_POWER=9
Note: CONFIG_OPENTHREAD_DEFAULT_TX_POWER is a value in dBm, valid range: -30 .. 9, by default it's zero.
Note: CONFIG_CHIP_OPENTHREAD_TX_POWER may used in older version.
In Matter root folder or /root/chip/
if using Docker image:
Activate Matter environment
source scripts/activate.sh
Go to directory with example:
cd examples/${app}/telink

White LED shows current state of Contact Sensor, Bolt Lock and Pump.
Short blinks in Lock app indicate transition state from Locked to Unlocked and vise versa.
For both Pump apps white LED shows the on-off-state of pump.
Blue LED indicates current Window Cover Lift position (PWM in range of 0-254).
To indicate the Tilt state in the same way connect external LED to board pin PE0.
A Bridge serves to allow the use of non-Matter IoT devices (e.g. devices on a Zigbee or Z-Wave net
work, or any other non-Matter connectivity technology) in a Matter Fabric, with the goal to enable
the consumer to keep using these non-Matter devices together with their Matter devices.
The Telink Bridge Example demonstrates a simple lighting bridge and the use of
dynamic endpoints.
The Bridge device performs the translation between Matter and other protocols so that the Matter nodes
can communicate with the Bridged Devices.
A Bridge may also contain native Matter functionality, for example,
it may itself be a Temperature sensor having both Thread and Zigbee connection.
As said in Matter Specification, this is illustrated in the figure below: the non-Matter devices are exposed as Bridged Devices to
Nodes on the Fabric. The Matter Nodes can communicate with both the (native) Matter devices as
well as the Bridged Devices (by virtue of the Bridge which performs the translation between Matter
and the other protocol).
Open Thread border router is composed device which contains two main parts:
Two devices can be used for creating RCP device.
In this case the RCP is an additional TLSR9518ADK80D board (B91 Generic Starter Kit).

Due to there's only one full featured UART port availabe on RPi 3, some additional actions are needed:
Disable console and logging over UART
Login into RPi via ssh and activate configuration tool:
sudo raspi-config
Sellect "3 Interface options"
Sellect "I6 Serial Port"
For "Would you like a login shell to be accessible over serial?" answer "No"
For "Would you like the serial port hardware to be enabled?" answer "Yes"
Close the tool by sellecting "Finnish"
Switch BLE chip to use miniUART instead of full featured UART
put:
dtoverlay=pi3-miniuart-bt
at the end of /boot/config.txt file
reboot the board.
sudo reboot
Configure GPIOs to act as HW flow control (RTS and CTS)
There are variety of tools to do that. The method tested and working is described below:
Login into Rpi console and fetch the tool:
git clone https://github.com/mholling/rpirtscts.git
Compile the tool:
cd rpirtscts/
make
Use the tool:
sudo ./rpirtscts on
The output should show which pins are used for HW flow control:
assuming 40-pin GPIO header
Enabling CTS0 and RTS0 on GPIOs 16 and 17
Shut down the board
sudo halt
Wait until "activity" (green) light stops flashing and power off the RPi board.
Connect Telink RCP to 40-pin headder of RPi

Commission could take some time. If commissioning is successful, you should
have the following message:
Device commissioning completed with success
In case of failures, the device configuration can be cleared using the following command:
sudo rm -rf /tmp/chip_*
It is highly recommended to use BLE 5.0 HCI conteoler on the host machine running chip-tool.
You can check HCI version:
hciconfig -a
It is possible to commision example Matter device without BLE conectivity, basing only on Thread.
Make sure OTBR (Open Thread Border Router) is up and running and network has been formed:
See Border Router section of this guide for details.
Join Matter Demo device using Button_3 (Joining Thread with hardcoded credentials):
Make sure red LED is lit with short pauses:
Beside LED indication, you can check is device joined using OTBR Web GUI (Topology)
Use chip-tool to perform "onnetwork" commisioning:
./chip-tool pairing onnetwork ${NODE_ID) ${PIN_CODE}
Example:
./chip-tool pairing onnetwork 1001 20202021
PIN_CODE can be obtained from Demo Device logs.
See Matter Firmware section of this guide for details.

fe80:0:0:0:1cef:9af0:c6a2:ab51
Done
choose address that coresponds with OTBR IPv6:LocalAddress. In this case:
fd11:22:0:0:1092:f710:43ba:bdb4
ping it from OTBR console:
pi@raspberrypi:~ $ ping6 fd11:22:0:0:1092:f710:43ba:bdb4
PING fd11:22:0:0:1092:f710:43ba:bdb4(fd11:22::1092:f710:43ba:bdb4) 56 data bytes

64 bytes from fd11:22::1092:f710:43ba:bdb4: icmp_seq=3 ttl=64 time=22.2 ms
In cae of failure:
check OTBR instalation and Thread NW forming. Check /var/log/messages for errors.
Use Matter Demo Device address obtained in 2. and ping it from host PC (machiner rynning chip-tool).
If ping from host PC works, chip-tool onnetwork pairing shall be working too. Remove cached data:
sudo rm -rf /tmp/chip_*
and check again:
./chip-tool pairing onnetwork ${NODE_ID) ${PIN_CODE}
In case of ping failure, it sometimes helps to unplug and plug back Ethernet connector from OTBR, but this manual is to serious to give such advice.

Binding links clusters and endpoints on both devices, which enables them to
communicate with each other.
To perform binding, you need a controller that can write the binding table
to the light switch device and write proper ACL to the endpoint light bulb
on the Lighting Example application.
For example, you can use the CHIP Tool as the controller.
The ACL should contain information about all clusters that can be called by
the light switch application.
See the section about interacting with ZCL clusters in the CHIP Tool's user
guide for more information about ACLs.
You can perform the binding process to a single remote endpoint (unicast
binding) or to a group of remote endpoints (group multicast).
Note: To use a light switch without brightness dimmer, apply only the
first binding command with cluster no. 6.
In this scenario, commands are provided for a light switch device with the
nodeId = <light-switch-node-id>
and a light bulb device with
nodeId = <lighting-node-id>
, both commissioned to the same Matter network.
To perform the unicast binding process, complete the following steps:
Add an ACL to the development kit that is programmed with the Lighting
Application Example by running the following command:
./chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null}, {"fabricIndex": 1, "privilege": 3, "authMode": 2, "subjects": [<light-switch-node-id>], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}, {"cluster": 8, "endpoint": 1, "deviceType": null}]}]' <lighting-node-id> 0
In this command:
[...]
is JSON format message for attr-value so <light-switch-node-id>
must be a real number when the command is<lighting-node-id>
can be a shell variable as ${NODE_ID} used{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null}
{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [<light-switch-node-id>], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}, {"cluster": 8, "endpoint": 1, "deviceType": null}]}
This command adds permissions on the lighting application device that
allows it to receive commands from the light switch device.
Add a binding table to the Light Switch binding cluster:
./chip-tool binding write binding '[{"fabricIndex": 1, "node": <lighting-node-id>, "endpoint": 1, "cluster": 6}]' <light-switch-node-id> 1
In this command:
[...]
is JSON format message for attr-value so <lighting-node-id>
must be real numbers when the command is executed.<light-switch-node-id>
can be a shell variable such as ${SWITCH_NODE_ID} used by chip-tool to do commissioning with Lighting Switch App.{"fabricIndex": 1, "node": <lighting-node-id>, "endpoint": 1, "cluster": 6}
is a binding for the On/Off cluster.The group multicast binding lets you control more than one lighting device
at a time using a single light switch.
The group multicast binding targets all development kits that are
programmed with the Lighting Application Example and added to the same
multicast group.
After the binding is established, the light switch device can send multicast requests, and all the devices in the bound groups can run the
received command.
In this scenario, commands are provided for a light switch device with the
nodeId = <light-switch-node-id>
and light bulb devices with
nodeId = <lighting-node-id>
, all commissioned to the same Matter network.
To perform the multicast binding process, complete the following steps:
Add the light switch device to the multicast group by running the
following command:
./chip-tool tests TestGroupDemoConfig --nodeId <light-switch-node-id>
<light-switch-node-id>
can be a shell variable such as ${SWITCH_NODE_ID} used by chip-tool to do commissioning with Lighting Switch App.Add all light bulbs to the same multicast group by applying command
below for each of the light bulbs, using the appropriate
<lighting-node-id>
(the user-defined ID of the node being commissioned
except <light-switch-node-id>
due to use this <light-switch-node-id>
for light-switch) for each of them:
./chip-tool tests TestGroupDemoConfig --nodeId <lighting-node-id>
<lighting-node-id>
can be shell variables as ${NODE_ID}s usedAdd Binding commands for group multicast:
./chip-tool binding write binding '[{"fabricIndex": 1, "group": 257}]' <light-switch-node-id> 1
<light-switch-node-id>
can be a shell variable such asTo test the communication between the light switch device and the bound
devices, use light switch buttons.
OTA feature enabled by default only for ota-requestor-app example.
To enable OTA feature for another Telink example:
CONFIG_CHIP_OTA_REQUESTOR=y
in corresponding "prj.conf" configuration file.After build application with enabled OTA feature, use next binary files:
All binaries has the same SW version. To test OTA "zephyr-ota.bin" should have higher SW version than base SW.
Set CONFIG_CHIP_DEVICE_SOFTWARE_VERSION=2
in corresponding "prj.conf" configuration file.
For Matter v1.0-branch branch used by default swap mode that run with the scratch partition (BOOT_SWAP_USING_SCRATCH
).
For Matter master branch used by default swap mode that can run without a scratch partition (BOOT_SWAP_USING_MOVE
).
To change swap mode back to BOOT_SWAP_USING_SCRATCH for master branch:
Remove -DCONFIG_BOOT_SWAP_USING_MOVE=y
cofing from build_mcuboot in CMakeLists.txt file.
Add scratch_partition into tlsr9518adk80d.overlay.
See Flash Layout and the following table for more details.
The following are the possible scratch partition layouts. Can be replaced with the one from the overlay file. The bigger scratch partition is the faster the swapping is done. Be aware that the bigger scratch partition is the smaller partitions for the code (slot0 and slot1) are.

Factory data is a set of device parameters written to the non-volatile memory
during the manufacturing process. This guide describes the process of creating
and programming factory data using Matter and the Telink platform from
Telink Semiconductor.
The factory data parameter set includes different types of information, for
example about device certificates, cryptographic keys, device identifiers, and
hardware. All those parameters are vendor-specific and must be inserted into a
device's persistent storage during the manufacturing process. The factory data
parameters are read at the boot time of a device. Then, they can be used in the
Matter stack and user application (for example during commissioning).
All of the factory data parameters are protected against modifications by the
software, and the firmware data parameter set must be kept unchanged during the
lifetime of the device. When implementing your firmware, you must make sure that
the factory data parameters are not re-written or overwritten during the Device
Firmware Update or factory resets, except in some vendor-defined cases.
For the Telink platform, the factory data is stored by default in a
separate partition of the internal flash memory.
You can implement the factory data set described in the
factory data component table in various ways,
as long as the final HEX/BIN file contains all mandatory components defined in the
table. In this guide, the generating factory data
and the
building an example with factory data
sections describe one of the implementations of the factory data set created by
the Telink platform's maintainers. At the end of the process, you get a HEX
file that contains the factory data partition in the CBOR
format.
The factory data accessor is a component that reads and decodes factory data
parameters from the device's persistent storage and creates an interface to
provide all of them to the Matter stack and to the user application.
The default implementation of the factory data accessor assumes that the factory
data stored in the device's flash memory is provided in the CBOR
format.
However, it is possible to generate the factory data set without using the
Telink scripts and implement another parser and a factory data accessor. This
is possible if the newly provided implementation is consistent with the
Factory Data Provider.
For more information about preparing a factory data accessor, see the section
about
using own factory data implementation.
Note: Encryption and security of the factory data partition is not provided
yet for this feature.

All parameters of the factory data set are either mandatory or optional:
user
data parameter consists of all data that is needed by aIn the factory data set, the following formats are used:
0
255
(inclusive), without any encoding.YYYY-MM-DD
or YYYYMMDD
format.By default, the factory data support is disabled in all Telink examples and
the Telink device uses predefined parameters from the Matter core, which
you should not change. To start using factory data stored in the flash memory
and the Factory Data Provider from the Telink platform, build an
example with the following option:
west build -- -DCONFIG_CHIP_FACTORY_DATA=y
This section describes how to generate factory data partition image.
Please make sure you have had the following tools before using the generator
tool.
Using the following commands to generate chip-tool, spake2p and chip-cert at
path/to/connectedhomeip/build/out/host
.
cd path/to/connectedhomeip
source scripts/activate.sh
gn gen build/out/host
ninja -C build/out/host
Add the tools path to \$PATH
export PATH="$PATH:path/to/connectedhomeip/build/out/host"
The factory data partition is an area in the device’s persistent storage where a factory data set is stored.
This area is configured in DTS file
For Matter v1.0-branch branch:
zephyr/boards/riscv/tlsr9518adk80d/tlsr9518adk80d.dts
For Matter master branch:
connectedhomeip/tree/master/src/platform/telink/tlsr9518adk80d.overlay
within which all partitions are declared.
To prepare an example that supports factory data, add a partition called factory-data
to the tlsr9518adk80d.dts
/tlsr9518adk80d.overlay
file. The partition size should be a multiple of one
flash page (for B91 SoCs, a single page size equals 4 kB).
See Flash Layout for an example of a factory data partition in the
tlsr9518adk80d.dts
/tlsr9518adk80d.overlay
file.
factory-data
partition size has been set to one flash page (4 kB).
To use this script, complete the following steps:
Navigate to the connectedhomeip
root directory.
Run the script with -h
option to see all possible options:
python scripts/tools/telink/mfg_tool.py -h

Note: By default, overwriting the existing output directory is disabled. This means
that you cannot create a new directory with the same name in the exact
location as an existing file. To allow overwriting, add the--overwrite
option to the argument list of the Python script.
You can manually generate the factory data set using the instructions described
in the Generating factory data section. Another way
is to use the Telink platform build system that creates factory data
content automatically using Kconfig options and includes the content in the
final firmware binary.
To enable generating the factory data set automatically, go to the example's
directory and build the example with the following option:
west build -- -DCONFIG_CHIP_FACTORY_DATA=y -DCONFIG_CHIP_FACTORY_DATA_BUILD=y
Alternatively, you can also add CONFIG_CHIP_FACTORY_DATA_BUILD=y
Kconfig
setting to the example's prj.conf
file.
Each factory data parameter has a default value. These are described in the
Kconfig file. Setting a new value
for the factory data parameter can be done either by providing it as a build
argument list or by using interactive Kconfig interfaces.
This way for providing factory data can be used with third-party build script,
as it uses only one command. All parameters can be edited manually by providing
them as an additional option for the west command:
west build -- -DCONFIG_CHIP_FACTORY_DATA=y --DCONFIG_CHIP_FACTORY_DATA_BUILD=y --DCONFIG_CHIP_DEVICE_DISCRIMINATOR=0xF11
Alternatively, you can add the relevant Kconfig option lines to the example's
prj.conf
file.
The HEX/BIN file containing factory data can be programmed into the device's flash
memory using BDT Tool
and the Telink burning key.
Another way to program the factory data to a device is to use the Telink
platform build system described in
Building an example with factory data,
and build an example with the additional option
-DCONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE=y
:
$ west build -- \
-DCONFIG_CHIP_FACTORY_DATA=y \
-DCONFIG_CHIP_FACTORY_DATA_BUILD=y \
-DCONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE=y
For better understanding various posibilities, see the table below:
Mode (described in the table below | (1) | (2) | (3) | (4) |
---|---|---|---|---|
CONFIG_CHIP_FACTORY_DATA | n | y | y | y |
CONFIG_CHIP_FACTORY_DATA_BUILD | don't care | don't care | y | n |
CONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE | don't care | n | y | y |
Mode | Description |
---|---|
(1) | hardcoded values will be taken |
(2) | Factory data partition image won't be merged into final binary. Partition image has to be flashed in the other way or runtime error will be reported on the startup, since factory data accessor expects partition to be in place |
(3) | Factory data partition image will be created by build system and merged into main binary. Recommended for development purposes. |
(4) | Build system expects externaly generated factory data partition image (egz. generated by the script described in "Script Usage" chapter) at the path used in connectedhomeip/config/telink/chip-module/CMakeLists.txt (egz. ${PROJECT_BINARY_DIR}/factory/factory_data.bin ) |
You can also build an example with auto-generation of new CD, DAC and PAI
certificates. The newly generated certificates will be added to factory data set
automatically. To generate new certificates disable using default certificates
by building an example with the additional option
-DCHIP_FACTORY_DATA_USE_DEFAULT_CERTS=n
:
$ west build -- \
-DCONFIG_CHIP_FACTORY_DATA=y \
-DCONFIG_CHIP_FACTORY_DATA_BUILD=y \
-DCONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE=y \
-DCONFIG_CHIP_FACTORY_DATA_USE_DEFAULT_CERTS=n
Note: To generate new certificates using the Telink platform build
system, you need thechip-cert
executable in your system variable PATH. To
learn how to getchip-cert
, go to the note at the end of
Creating a factory data partition with the second script
section, and then add the newly built executable to the system variable PATH.
The Cmake build system will find this executable automatically.
After that, use the following command from the example's directory to write
firmware and newly generated factory data at the same time:
west flash
The factory data generation process described above
is only an example valid for the Telink platform. You can well create a HEX
file containing all Factory data component table in any
format and then implement a parser to read out all parameters and pass them to a
provider. Each manufacturer can implement a factory data set on its own by
implementing a parser and a factory data accessor inside the Matter stack. Use
the Telink Provider
and FactoryDataParser as
examples.
You can read the factory data set from the device's flash memory in different
ways, depending on the purpose and the format. In the Telink example, the
factory data is stored in the CBOR
format. The device uses the
Factory Data Parser to read
out raw data, decode it, and store it in the FactoryData
structure. The
Factor Data Provider
implementation uses this parser to get all needed factory data parameters and
provide them to the Matter core.
In the Telink example, the FactoryDataProvider
is a template class that
inherits from DeviceAttestationCredentialsProvider
,
CommissionableDataProvider
, and DeviceInstanceInfoProvider
classes. Your
custom implementation must also inherit from these classes and implement their
functions to get all factory data parameters from the device's flash memory.
These classes are virtual and need to be overridden by the derived class. To
override the inherited classes, complete the following steps:
Override the following methods:
// ===== Members functions that implement the DeviceAttestationCredentialsProvider
CHIP_ERROR GetCertificationDeclaration(MutableByteSpan & outBuffer) override;
CHIP_ERROR GetFirmwareInformation(MutableByteSpan & out_firmware_info_buffer) override;
CHIP_ERROR GetDeviceAttestationCert(MutableByteSpan & outBuffer) override;
CHIP_ERROR GetProductAttestationIntermediateCert(MutableByteSpan & outBuffer) override;
CHIP_ERROR SignWithDeviceAttestationKey(const ByteSpan & messageToSign, MutableByteSpan & outSignBuffer) override;
// ===== Members functions that implement the CommissionableDataProvider
CHIP_ERROR GetSetupDiscriminator(uint16_t & setupDiscriminator) override;
CHIP_ERROR SetSetupDiscriminator(uint16_t setupDiscriminator) override;
CHIP_ERROR GetSpake2pIterationCount(uint32_t & iterationCount) override;
CHIP_ERROR GetSpake2pSalt(MutableByteSpan & saltBuf) override;
CHIP_ERROR GetSpake2pVerifier(MutableByteSpan & verifierBuf, size_t & verifierLen) override;
CHIP_ERROR GetSetupPasscode(uint32_t & setupPasscode) override;
CHIP_ERROR SetSetupPasscode(uint32_t setupPasscode) override;
// ===== Members functions that implement the DeviceInstanceInfoProvider
CHIP_ERROR GetVendorName(char * buf, size_t bufSize) override;
CHIP_ERROR GetVendorId(uint16_t & vendorId) override;
CHIP_ERROR GetProductName(char * buf, size_t bufSize) override;
CHIP_ERROR GetProductId(uint16_t & productId) override;
CHIP_ERROR GetSerialNumber(char * buf, size_t bufSize) override;
CHIP_ERROR GetManufacturingDate(uint16_t & year, uint8_t & month, uint8_t & day) override;
CHIP_ERROR GetHardwareVersion(uint16_t & hardwareVersion) override;
CHIP_ERROR GetHardwareVersionString(char * buf, size_t bufSize) override;
CHIP_ERROR GetRotatingDeviceIdUniqueId(MutableByteSpan & uniqueIdSpan) override;
Move the newly created parser and provider files to your project directory.
Add the files to the CMakeList.txt
file.
Disable building both the default and the Telink implementations of
factory data providers to start using your own implementation of factory data
parser and provider. This can be done in one of the following ways:
CONFIG_CHIP_FACTORY_DATA_CUSTOM_BACKEND=y
Kconfig setting to prj.conf
west build -- -DCONFIG_CHIP_FACTORY_DATA_CUSTOM_BACKEND=y
