I haven't seen it mentioned yet so worth a try: have you looked at the kernel log for hints?
I looked and the only thing I saw was EDID logging

Wtf is this error? I'm trying to build the kernel for this system.

@rosscomputerguy:matrix.orgTristan Ross Hmm, if I override it so CONFIG_DEBUG_INFO_BTF=n is set then it builds 03:58:23
@rosscomputerguy:matrix.orgTristan RossGreat, I think I have all of the binaries I need. I have the kernel, secboot-fw, nsign, and u-boot. Now I need to figure out partitioning and I should be able to boot this.05:48:33
