Imx8mm build instructions do not work

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?

As a follow up, I’m sure many of you are already aware that has closed down.

The official instructions build instructions at need to be updated with corrected information to build the Mini image.

@mmundy3832 What was it you had to do to build for the mini? I am confused because I only see a machine conf file for imx8mp and a dtsi for imx8mp-hummingboard-pulse, not imx8mm-hummingboard-pulse or imx8mm machine conf. Thanks.
