/dev/ttyRPMSG0: no such file or directory

[TArre.1]

Hello!

I am trying to replicate the workshop STM32MP1 - 11 Inter-Processor Communication Lab Example. I create a new STM32 project and copy all the data from the lab example. Then I connect the device (STM32MP157C-DK2) in production mode to send message between processor but the following message appears in the terminal:

• /dev/ttyRPMSG0: no such file or directory

 

Can somebody help me?

Thanks!

I have updated to the last version of the firmware but I am still having the same problem.

In the .ioc part I have only configured the timer and the led pin (PH7). Do I have to do any more configuration? I have copied the rest from the example.

Thanks!
