I seem to be getting a black screen on bootup.
This is running on a Canakit PI3B+
Looks like a CMA error.
What size screen was this public image tested on? The screen I connected
was a 1920x1080 resolution.
Does it need to be smaller than that?
Can you set the CMA higher before install time? If so what is the proper
values for a 1920x1080 screen?
