I'm interested in learning about TF-A, OPTEE, are some demos concerning these topics available?Is it possible to debug the CortexA core, through the embedded ST-LINK? I mean working solution, not in theory?What would be limitations debugging very ear...
Hi,I am only a bit familiar with embedded linux. I will develop a demo project with STM32MP157C-DK2 with C language:on M4 side, a sensor(BME280) and a vantilator (5v) are connected. Sensor is to read periodically and three numerical values( temp, hum...
Hello,I have 4 questions if you have time to answer, I would appreciate it very much.I prepared st-example-image-qt image. But there isnt any terminal like weston image. Should I run any other command before bitbake in order to have all the tools pac...

Lets say I need to separate module, one will contain the pcb with mpu and other IC, the second will contain a touchscreen display and sensors. The modules are 2 meters apart. What should I use hdmi or mipi? How do I send mipi over distance?
Can anyone point me to an example on how to use bluetooth for this discovery board? Will it be possible to pair to two bluetooth sensors at the same time?
I wrote an application on the STM32MP157C-DK2, and m4 reads the data of an external adc and sends it to A7 for processing. The entire program got stuck after running for about 15 hours. The console has been outputting the following content[84306.5118...
The routine I tested was stm32mp157\STM32Cube_FW_MP1_V1.0.0\Projects\STM32MP157C-DK2\Applications\OpenAMP\OpenAMP_TTY_echo, The test method is guided by the following address, https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP1...
I'm trying to image the provided SD Card. I'm trying to use `dd` but it seems to only be cloning about 33mb before saying it is finished with no other output. sudo dd if=/dev/disk2 of=~/stmicro.imgAny thoughts?
