I am in the process of evaluating new imx8mm boards for a project, and this is my first time to use them. I followed the instructions at GitHub - SolidRun/meta-solidrun-arm-imx8 at kirkstone-imx8m because I need an Ubuntu image for my project.
I was fairly certain that this would not work because of the imx8mp setting (rather than imx8mm). It appears that I was right, and the imx8mp image fails to output any messages to the serial port at all.
I accidentally attempted to boot with a Debian imx8mq, and that was not compatible with the Mini. When I realized this mistake, I did get Debian imx8mm to boot up.
Where can I find the build instructions for imx8m Mini to build the most up-to-date Ubuntu?
