I am working with iMX8 Nano Evaluation board. I want to use the RPMSG communication framework to establish communication between the M7 and A53 core. I have been able to do this with Linux running on A53 and M7 running an example str echo application from the MCUXpresso SDK. I want to now use the same framework for communication between the cores with A53 running android and M7 running the example application. I have been able to locate the .ko file required on Android. But when I try to use the insmod command, the program does not run. I found that the rpmsg driver that is required to be enabled is not enabled in the linux kernel of the android. I want to enable this driver while building the linux kernel. Could someone help me out in building this kernel without using Yocto Project?
I believe that you have followed this guide here: https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Using-Cortex-M4-SDK-to-communicate-with-...
am I correct?
Please make sure to add the RPMSG module before building the android image.
