Long story short, I accidentally removed all the contents of the /boot folder 😢.
I'm running minimal Armbian 24.5.1 Bookworm with Linux 6.1.43-vendor-rk35xx on Orange pi 5 plus.
It all started with a failed apt update indicating there wasn't enough space in the boot partition. The update was trying to install 6.1.75-vendor-rk35xx kernel, so I decided to remove the old one from the boot to free up some space. Instead, I accidentally applied 'rm -r' to the entire /boot folder. My SBC is working fine now, but I'm afraid it won't boot on next restart, so I'm looking for a way to recover the files.
So far, I performed apt upgrade, which put the new 6.1.75-vendor-rk35xx kernel in the boot, but I'm not sure if it installed correctly - there was a warning that it couldn't be done automatically since there were no headers. I also copied armbianEnv.txt and boot.cmd from Armbian_24.5.3_Orangepi5-plus_bookworm_vendor_6.1.43_minimal.img so now armbianEnv.txt looks like below:
verbosity=1
bootlogo=false
console=both
overlay_prefix=rockchip-rk3588
fdtfile=rockchip/rk3588-orangepi-5-plus.dtb
rootdev=UUID=0af659d6-5b18-4106-9904-3ec2a1445b8a
rootfstype=ext4
Finally I used u-boot-tools to make boot.scr:
mkimage -C none -A arm -T script -d boot.cmd boot.scr
Did I miss anything, or am I good to try restarting the SBC and see how it goes 😅?
