Hi there,
Armbian with 3.4.x Kernel has been running fine on my CubieTruck until upgrading to 5.25. Armbian is installed on NAND (using nand-sata-install), and there is also a SDcard and a harddrive connected for data storage.
Some days ago the upgrade to Armbian 5.25 appeared and I did a sudo apt-get dist-upgrade. It took a long time and threw some warnings and errors - which I probably should have captured. I recall something regarding "cannot link image" or so... The whole upgrade finished completely at the end. Then the reboot...
Now the the CubieTruck is not booting anymore. The error message is:
U-Boot 2017.1-armbian

Error: no valid bmp image at 66000000

Then it starts searching for a boot image via TFTP.
What can I do? Do I need to reinstall? Is it possible to just change some files, links, etc. to get it booting again?
