Hi,

Hi @arunsathian 

You can't use it directly, there are lots of changes in framework and dts.

Hi @Zhiming_Liu
what are the changes need to be done in this patch file?Can you please explain in a brief?

[Zhiming_Liu]

The device tree changes a lot(arch/arm64/boot/dts/freescale/imx8qxp-mek-rpmsg.dts), and L5.10 don't use rpmsg driver anymore, it uses remoteproc framework.

Hi @Zhiming_Liu
Are you saying that for L5.10 version we strictly need to use remoteproc instead of rpmsg?
If do so can you please share any documents related with it.
