[OpenAMP] Cannot initialize ttyRPMRSG0 configuration

[TClar.18]

I am programming a STM32MP157C-DK2 board using System Workbench. I have been able to run the OpenAMP_TTY_echo example project without trouble. Then I created a new project and generated OpenAMP middleware from CubeMX. No trouble while compiling and uploading the firmware. But I have been able to test the firmware because of this error (see image below).

Am I missing something? Please share any hint that could help!

Thanks,

Tristan

Hello, I tried it on my PC it works well, I think you have to try it with System Workbench for STM32.

1- Connect the card to the PC

2- Download the firmware

3- Open the console on the serial device

I also tried it with SSH instead of the System Workbench console.

And it works:

Thank you

Hi @Community member​ 

/dev/ttyRPMSG0 is only created after call to VIRT_UART_Init(&huart0) ... which is not part of code generated automatically by CubeMX.

Hope it help,
