How old is the u-boot build on this platform?
U-Boot 2018.03-devel-18.12.3-g926d08c7ce (Apr 11 2022 - 15:48:13 +0800)
This appears to be the most recent version the manufacturer has released for this device. Source: https://github.com/globalscaletechnologies/u-boot-marvell.
arch/arm64/boot/marvell/armada-3720-espressobin-ultra.dts
This is a uboot path, right? Not a linux path? Are you sure this DTS is compatible with the v6.5 kernel?
Sorry for the confusion; that is the path in the linux source to the DTS used to compile the DTB that I am using to boot the device. I booted v5.15.135 using the DTB compiled from v6.5.7 source and that works fine. I also tried to boot v6.5.7 with the factory DTB and that failed.
Please add message inside the update_fdt() routine...
I added a bunch and here's what I got back:
EFI stub: Booting Linux Kernel... EFI stub: ERROR: FIRMWARE BUG: efi_loaded_image_t::image_base has bogus value EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary EFI stub: ERROR: Failed to install memreserve config table!

That's as far as I could get today but hopefully that starts to narrow it down. Appreciate the help!
Sincerely,
Ben
