The X-LINUX_OTBR_POSIX is a linux Package running on STM32MPU and tested on STM32MP157F-DK2. Openthread Border Router(OTBR) work with Radio Co Processor(RCP) STM32WB55 through a serial connection (FTDI) between STM32MPU and STM32WB. This meta-layer provide all recipes needed to compile ot-br-posix "https://github.com/openthread/ot-br-posix" on stm32mpu.
Two cases for RCP are available :
Matter/Openthread : Follow this github RCP-MATTER
Openthread standalone : Follow this github RCP-OPENTHREAD

Openthread Boarder Router
-
as Thread RCP firmware P-NUCLEO-WB55 ST Radio Co-Processor (RCP) if used
A Linux® PC running under Ubuntu® 18.04 or 20.04 is to be used. The developer can follow the below link. https://wiki.st.com/stm32mpu/wiki/PC_prerequisites
This is required to build the recipes and create STM32MP1 images (see https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package).
Create source folder
PC $> mkdir ~/stm32mp1_openthread
PC $> cd stm32mp1_openthread
Initialize repo in the current directory
PC $> repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23
Synchronize the local project directories with the remote repositories specified in the manifest (more details on 'repo sync' here)
PC $> repo sync
Initializing the OpenEmbedded build environment
PC $> DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
PC $> bitbake st-image-weston
PC $> cd ~/stm32mp1_openthread
PC$> git clone "https://github.com/stm32-hotspot/stm32mp1-otbr-posix.git"
PC$> bitbake-layers create-layer ../layers/meta-st/meta-otbr
PC$> cp -r ./meta-st-x-linux-otbr-posix/meta-otbr ./layers/meta-st/
PC$> bitbake-layers add-layers ./layers/meta-st/meta-otbr
PC$> bitbake st-image-otbr
The build--/tmp-glibc/deploy/images/stm32mp1 directory receives complete file system images.
Note that the build of the Distribution Package generates the images and the Flash layout files
- MB1272 motherboard: STM32MP157x 12x12, PMIC, DDR3
- MicroSD card slot
- 2 x USB Type-A (host) → mouse, keyboard or USB driver
- 2 x USB Type-A (host) → mouse, Keyboard or USB driverUSB
- micro-B (ST-LINK/V2-1) → PC virtual COM port and debug
- Reset button
- Ethernet → Network
- USB Type-C (power 5V-3A)
Let's flash the downloaded image on the microSD card:
- Set the boot switches (1) to the off position
- Connect the USB Type-C™ (OTG) port (2) to the host PC that contains the downloaded image
- Insert the delivered microSD card into the dedicated slot (3)
- Connect the delivered power supply to the USB Type-C™ port (4)
- Press the reset button (5) to reset the board
- Launch STM32CubeProgrammer to get the GUI
- On the top right of the window, select USB (instead of STLINK, set by default) in the connection picklist and click the "Refresh" button. The serial number is displayed if the USB is detected. Then click "Connect".
- Refresh and press to Connect
-
Select the "Open File" tab and choose the "FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv" through this path build--/tmp-glibc/deploy/images/stm32mp1/flashlayout_st-image-otbr/extensible
-
Fill the Binaries Path" by browsing to the "build--tmp-glibc/deploy/images/stm32mp1/
command lines can be run from Terminal through USB with st-link
Note: in this article, any command executed on the board (through the remote Terminal or the Wayland Terminal) starts with BOARD$> , while any command executed on the host PC starts with PC$>
