This is my first time on working with capes on a BB and am having a little difficulty getting the Load Cape dtbo to load. I have been combing the google and the forums for solutions and I think figured out how it is supposed to work. I am running the following Linux version:
Linux BeagleBone-AI64 6.6.58-ti-rt-arm64-r17 #1 SMP PREEMPT_RT Wed Jan 15 04:58:38 UTC 2025 aarch64 GNU/Linux
I’m getting the following output from my console on booting:
Retrieving file: /Image
append: console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmclk0p2 ro rootfstype=ext4 rootwait net.ifnames=0

I downloaded the BeagleBoard Device-Tree branch, thread dtb-6.6, and have rebuilt and installed it.
I need some advice on how to get a little more detail on what is wrong with the dtbo file. u-Boot output doesn’t give me much information.
