Rock64 Debian 11 (Bullseye) install problem

[jbize]

Well, I spent half a day on this and in the end found several solutions.

The solution that worked best for me in the end was:

• Download, burn, and install Armbian_21.08.1_Rock64_bullseye_current_5.10.60.img.xz to a microSD as a "rescue image".
  

• Insert the newly installed/created (but not yet bootable) Debian 11 microSD into a USB adapter and inert in Rock64.
  
• Power up and boot Armbian "rescue image."
  
• Log in as root and:
  

•     apt install -y u-boot-rockchip
  

•     u-boot-install-rockchip /dev/sda
  

That's it.  The new Debian 11 microSD in the USB adapter is now bootable.  Move it to the microSD slot and reboot.

There are also some "side-boot", what I referred to as "boot to" (and flashing) programs available:

• apt install -y python3-pip rkflashtool
  
• pip3 install pyamlboot
  

Thanks as365n4 for pointing me to the u-boot-install-rockchip package.

The main issue I was having was either booting my new image, or booting an image I could use to write the u-boot partition.
