Subject: RPmsg in pico-imx7d using mainline linux (5.6.xx) and Yocto dunfell

Message-ID: <K7EX.1629078628762187651.Lt8M@lists.yoctoproject.org> (raw)

I have been interested in communicating between the a7 and the m4 of my imx7d-pico using RPmsg for a long time.
Today I found that this tutorial:https://www.youtube.com/watch?v=4zMyjaEgj2U&t=1182s
I don’t use mainline linux. I stay using kernel 5.6.xx with libgpiod 1.5
Using libgpiod I want to press a controlled button on a7 and flash an LED (which is waiting for this command) on m4
*I was checking the issue link below and I have 2 questions below:*
*https://community.nxp.com/t5/i-MX-Processors/I-cant-get-the-linux-side-of-yocto-rpmsg-example-for-imx6sx/m-p/490383*
1 - How can I adapt this project: https://hub.mender.io/t/technexion-pico-pi-imx7/136/6 ( https://hub.mender.io/t/technexion-pico-pi-imx7/136/61 )
to the nxp forum project (link above) for me to get the following files: mu.c, imx_rpmsg.c, imx_rpmsg_tty.c and/or imx_rpmsg_tty.ko
2 - What is the best way to do RPmsg communication between a7 and m4 using Yocto on a7?
