I'm narrowing in on the issue.
I have a BeagleBoard.org OS image release where I can see PowerVR running,
and PCIe (WiFi/BT) works:
* bbai64-emmc-flasher-debian-11.7-xfce-edgeai-arm64-2023-09-02-10gb.img
Rescue option 1 (default image panics when booting with PCIe populated):
[ 0.000000] Linux version 5.10.168-ti-arm64-r111 (voodoo@AM69-SK-32g-01)
(gcc (Debian 10.2.1-6) 10.2.1u3
These images use a device tree from a different repo than the ti-kernel
repo:
kernel: https://github.com/beagleboard/linux.git
dt:
https://git.beagleboard.org/beagleboard/BeagleBoard-DeviceTrees
Dumping the DT from Yocto linux-bb and BeagleBoard.org the output is not
the same.
Proposed minimum changes:
* add option for BeagleBoard-DeviceTree
* update kernel versions in linux-bb
* update PowerVR version to match kernel/DT
Thoughts?
