Great! That worked. Do I need to do anything else after that?

I can confirm this is still broken as of 10/18/2025 Currently attempting the overwrite armbian uboot with vendor uboot solution The solution did work. The spl loader files can be found here https://dl.radxa.com/rock5/sw/images/loader/rock-5b/release/ All of the files need to be gathered together, or the file paths adjusted when you run the commands. I pulled the rkdeveloptool from git and built it and put everything else the folder with it. ❯ ./rkdeveloptool ld DevNo=1 Vid=0x2207,Pid=0x350b,LocationID=101 Maskrom ❯ sudo ./rkdeveloptool db rk3588_spl_loader_v1.15.113.bin Downloading bootloader succeeded. ❯ sudo ./rkdeveloptool wl 0 armbian.img Write LBA from file (100%) ❯ sudo ./rkdeveloptool wl 64 idbloader.img Write LBA from file (100%) ❯ sudo ./rkdeveloptool rd Reset Device OK.

I finally installed Postmarket OS (Alpine Linux) using Pmbootstrap., I close this topic. Thanks to all of you for your comments and suggestion.

You seem to have the older obsolete special RPI5 build, that doe not exist anymore, it is just 1 RPI build called 'rpi4b' So remove armbian-bsp-cli-rpi5b-current as well apt update dpkg --remove --force-all libraspberrypi0 armbian-bsp-cli-rpi4b-current armbian-bsp-cli-rpi5b-current apt --fix-broken install apt install armbian-bsp-cli-rpi4b-current

So, I have now tried to solve the problem using the instructions. But unfortunately, it didn't work and I am getting an error message again. I ask for further assistance.
