RPmsg enabling in i.MX8QXP

[arunsathian]

Hi,

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

Hi @arunsathian 

Also answer thread here:https://community.nxp.com/t5/i-MX-Processors/RPmsg-sample-code/td-p/1831691

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
