Looks like I accidentally erased most of my u-boot from SPI flash since I don't have much experience with it. Are there any ways to restore it and what soft- and hardware do I need, apart from having a Linux PC and UART?

Updating U-Boot was the solution, kernel is now up to date!!! Thanks everyone for the tips, learned a few new things and the UART cable is really usefull!

@Werner @SteeMan Hah, I legit didn't know about the armbian-install command. I updated the bootloader and I guess I'm more up to date now U-Boot on boot is now U-Boot 2026.04_armbian-2026.04-S88dc-P3cfe-H5025-V315b-Bd0d2-R448a (May 30 2026 - 05:51:20 +0000) odroid-n2/n2-plus Gonna try to update the kernel now

Much to my chagrin I have had to do a similar dance today after running updates./. I tried sudo dpkg-reconfigure aic8800-usb-dkms but no joy. This time was easier and it was just a matter of getting the firmware and usb module directly from radxa's repo. ```wget https://github.com/radxa-pkg/aic8800/releases/download/5.0%2Bgit20260123.5f7be68d-6/aic8800-firmware_5.0+git20260123.5f7be68d-6_all.deb wget https://github.com/radxa-pkg/aic8800/releases/download/5.0%2Bgit20260123.5f7be68d-6/aic8800-usb-dkms_5.0+git20260123.5f7be68d-6_all.deb``` Then install both of them ```sudo dpkg -i aic8800-firmware_*.deb aic8800-usb-dkms_*.deb``` and then remapping the hardware and restarting ```sudo depmod -a sudo reboot``` Leaving this there... for next time I do an update
