Hi,

How we can enable the RPmsg in i.MX8QXP for inter core communication (A35 & M4).Can you share any documents related with it.

For SDK source code, you can go to mcuxpresso SDK website, choose your board and download your SDK.

For enabling rpmsg, you need use imx8qxp-mek-rpmsg.dtb in kernel and refer the AN14120.pdf.

Best Regards

Zhiming
