Hi,
Sorry to hijack an existing thread, but I think this is a generic, uboot issue that is hitting at least some allwinner boards, and is related to ROCK(Pro)64 won't boot with Linux 6.12
Some history:
I’m new to the forum, having just migrated to DietPi from Armbian on a Pine64+ (A64 2GB).
The board has been running Armbian since 2017, first on the original “longsleep” kernel, then from 2021 on mainline (Ubuntu Focal), using a reduced footprint. I have been using it as a dedicated squeezebox touch replacement, running squeezelite and jivelite, with fb output to the lcd touchscreen. ref: Pine64 as squeezebox touch replacement
This was working fine, with regular apt updates until some time after kernel v. 6.x broke the display and some other bits of the squeezelite implementation, which I didn’t investigate.
The device did continue to boot, so I tried sporadic updates, hoping they might fix the issue, until last week.
I tried various Armbian releases, and found that somewhere between around 6.6.x and 6.12.x, the 7” lcd goes blank and there are other weird issues including network connectivity and DHCP problems. The latest Arbmian releases and updates also fail to load the 7" screen overlay, no matter what armbianEnv settings I tried. So I found DietPi and can successfully load the dtbo.
Status is that the lcd monitor is picked up at boot, and the backlight works and can be controlled, but neither console, nor random output to /dev/fb0 will display anything.

Unfortunately I don’t have a serial console cable to debug the boot loader process.
If this looks like part of the memory space issue that was discussed in the ROCK(Pro)64 won’t boot with Linux 6.12 thread, was there an experimental uboot patch that I might try for the Pine64?
Update:
More info:
DietPi v9.19.2 : 08:31 - Sat 11/29/25
─────────────────────────────────────────────────────
* Device model : PINE A64 (aarch64)
* CPU temp : 34 °C / 93 °F
I have nothing connected to hdmi, so if this can be completely disabled as part of the debugging process, that would be fine for me
