Hello,
i did some more testing with core 172 and 173 not working anymore when booting from SD Card - You get an Error:
USB XHCI 1.00
scanning bus xhci_pci for devices… Unexpected XHCI event TRB, skipping… (3df5d620 00000004 01000000 01008401)
BUG at drivers/usb/host/xhci-ring.c:530/abort_td()!
BUG!
resetting …
I now had a look which files where changed from core 171 to 172/173.
Following the boot order the Raspberry / U-Boot does i just did a simple test:
I moved the u-boot-rpi4.bin file from 171 SD card to a 173 SD card - And it is working. So, something must have changed in the u-boot image to trigger the XHCI error.
Don’t know if this is “good” to use the old u-boot file, but it seems to be working without any issues. Maybe someone who has more glue, what is inside this bin file and tell what in regards of xhci could have changed, can have a look at it?
(I also read somewhere, there may be a possible bug in u-boot - But as there is no newer version in the stable firmware channel from rpi-eeprom-update than the 11.01.2023 i can not tell if this can be the source of the issue - maybe i will try to get a firmware from beta branch and see if this issue still occurs)
Greetings
