Hi experts,
I am using imx8mq board to develop rpmsg in my project. I am running Android 11.0.0_2.0.0. I flashed the M4 image along with Android images with "uuu_imx_android_flash.sh" script. And in uboot I set bootcmd as below:
At first, M4 run normally as expected, But after few seconds, M4 program crashed and Android run normally.
What's the problem maybe?
Thanks
Edward
Thanks,
I have solved the rpmsg problem.
What you said is about solveing M4 crashing when using UART2? You mean uart2 clock is enabled by A-core not by M-core. I donot agree with you, if as you said, why M4 can run with UART2 printing alone without runging A-core.
HI ,
I am facing similar problem, in linux, I was able to see the /dev/ttyRPMSG node when I was working with 4.14.98 kernel, I recently changed to 5.10.72.x , I am not seeing the node.

I see the log, but /dev no node.
Can you share what you did to fix your issue.
Thanks
