Technexion PICO-PI-IMX7

@texierp @drewmoseley

hi,
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: Linux and Zephyr “Talking” to Each Other in the Same SoC - Diego Sueiro, Sepura / Embarcados - YouTube

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:

  1. How can I adapt this project by @jorisoffouga
    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?
