Hi,
I'm having an issue while trying to debug the OpenAMP_TTY_ECHO_CM4 example described in gettin' started guide for stm32mp157a-DK1 (here link) using Cude IDE 1.4.2 on windows 10 machine. I configure the debug session as describe in the guide section 7, but when I started it, I got the following messages:

When I reopen a serial console on cube IDE to run the test (according to guide section 8), I can't find any /dev/ttyRPMSG0 or /dev/ttyRPMSG1 device.
Please someone could help?
Marco.
