Is there any OpenAMP, RPMSG, simple C example? I am trying to learn more about IPC from user-space and I am looking for a simple C example that can send messages to ttyRPMSG0 in STM32MP1.
Hey there, I am new to STM32MP1 and this forum has been a great help. During the last week I am trying to understand the OpenAMP between the M4 and A7. The ttyRPMSG makes things quite straight forward for the M4 part. When going to the linux part, us...
OPENAMP in A7 side is blocked when another process is use CPU for calculation？
I create a process A to communicate with M4, another process B every 2 min will be calculate some data cost 230ms. in this inteval, process A cant use OpenAmp to send cmd to M4, until process B complete the calculation.

Resolved! STM32MP157 run, not debug, M4 in engineering mode?
For one project we would want to use only de M4 core of the SM32MP157 MPU. We want this because we have no time to learn how to develop the whole application using linux and the whole potential of the MPU, but we would want to have the hardware ready...
