SoMLabs VisionSOM-STM32MP1 and VisionCB-STM32MP1-STD board problem with developing software on Cortex-M4 core.

I have a problem with running the software on the Cortex-M4. Probably the default device tree configuration does not start the m4 core.

Has anyone used a SoMlabs board and tried to run software on the Cortex-M4 core?

Hi @Konrad Wójcik​ 

Could you please confirm that the binary is present in /lib/firmare on target ?

Thanks

Olivier

Yes, the binary file is in a correct folder. Thank you for your answer =)

I solved the problem. I edited the generated device tree file from the CubeMX, adding memory-region for the Cortex-M4. I compiled the new device tree and replaced the appropriate files on the SD card with OpenSTLinux.

Best regards,

cien
