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:
-
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 -
What is the best way to do RPmsg communication between a7 and m4 using Yocto on a7?
