Hi Neuber,

I think you forgot to hit reply-all.

Hi Fabio,

In this video: https://mail.google.com/mail/u/0/?tab=rm&ogbl#all/FMfcgzGkZsrTzPBfwTMTnDdMWlJRQlCW

at 23 minutes and 17 seconds, Diego Suero uses the following files:

../arch/arm/mach-imx/mu.c
../drivers/rpmsg/imx_rpmsg.c
../drivers/rpmsg/imx_rpmsg_tty.c

What are the equivalent files (on mainline linux, one of them seems to be: ../drivers/remoteproc/imx_rproc.c)
so that I can implement RPmsg on mainline linux/device tree correctly?
The mailbox driver is at drivers/mailbox/imx-mailbox.c in mainline.


Or is the approach to mainline linux (RPmsg) in imx7d-pico different?


i.e.:I haven't had any problems with dunfell using kernel 5.6.xx at the moment.
Sure, feel free to use it. It is just that you will not get any
support from the community using this version.

Personally, I haven't used the remoteproc driver in mainline, so I
can't help you.
