Linux 2.8 flashed with your original flash image: Colibri-iMX7_LXDE-Image_2.8b6.184-20190401.tar.bz2 worked. The rpmsg device was operational. /dev/ttyRPMSG0 was visible and running.
I loaded from git: colibri-imx7_lxde-image-tezi_2.8b6.184-20190401.tar
I executed: make colibri_imx7_defconfig
I built successfully. Merged zImage into the volume used by UBoot to flash the iMX7.
Linux up and running.
MU is ready for cross core communication! imx rpmsg driver is registered [FAILED] Failed to start Load Kernel Modules
Running systemctl status systemd-modules-load.service didn’t say explicitly what is wrong.
Am I missing some step in the build process?
