NanoPC T6 not booting

[J-Twin]

Hello,

I have installed the noble and trixie images to a known good SD card but neither image will boot on my T6. There is nothing displayed at the screen which is using HDMI cable. Same SD card is booting Armbian running kernel 6.1. I have successfully installed Armbian at the attached NVME disk.

I cannot get any logs as it does not actually boot.

Connect to the UART console and show the complete log output during boot.

I experience the same thing, it will not boot. I try to mount the boot image and get an error stating that there is some thing wrong with /dev/loop

Connect to the UART console and show the complete log output during boot.

Things are not looking good at all! System gets in a boot loop shortly after loading the kernel:

This is the problem. DTB is corrupt for some reason.

[J-Twin]

Is there a way to dig into this?

SD card used to write the image file is in good condition. The same card was used to boot another noble image with success:
https://github.com/Joshua-Riek/ubuntu-rockchip/releases/download/v2.1.0/ubuntu-24.04-preinstalled-desktop-arm64-nanopc-t6.img.xz

That image has the "dfs get fsp_params" error too but boots normally

[johang]

I would go into the U-Boot console at Hit any key to stop autoboot: 0, run the boot script manually and then inspect the contents of at the DTB address.

Hello, I have updated bootloader to v1.16 from v1.08 but problem remains.

This bootloader along with friendlyelec U-Boot SPL are able to boot properly all Armbian SD images.
