Use remoteproc to start M7 core on Verdin iMX8M-Plus

Hi @vix !

I just answered a related question here:

Need help to set up rpmsg on dalhia board with imx8m-plus

I’m trying to get rpmsg working on a dalhia board with imx8m-plus. Using the toradex kernel and the provided device tree. Read all the relevant questions on the forum yet i can’t find a way to get it working. On the M core side,the example rpmsg string echo program is launched. When i add the rpmsg_tty module on the linux side, /dev/ttyRPMSG30 is successfully created but the M core still hangs on the call to rpmsg_lite_wait_for_link_up. I’ll gladly provide missing information if any, hopin…

As you can see, it worked for me.

Could you please follow each step of the article How to Use RemoteProc | Toradex Developer Center and share the output here?

Also, please share the output of tdx-info.

Best regards,
