IMX7 : enable RPMSG

Hi @henrique.tx

Thank you .
Best regards,

Shooting here there will double your problems. M4 freeze is another issue. Without “okay” in /sys/firmware you won’t be able to use RPMSG!

M4 freeze among other issues may be caused at least by some other unrelated Linux peripheral, which may have same root clock as M4, like here:
IMX7D M4 freeze when booting Linux - Technical Support - Toradex Community

the status is okay , You can see here :

I am also trying to locate the source of problem, and made some tests to locate the problem, I had noticed that cortex m stopped when running Linux, and I fixed it .
