This process did not work from Windows 11 for a ROC-RK3328-CC target.
- I flashed the board-specific version of LEFT to a uSD card using Etcher (worked fine)
- Created the new NTFS simple volume per the instructions
- Copied the desired OS image as flash.img to the new volume
- Ejected the uSD card from the Windows machine
- Installed the uSD card in the Renegade
- Booted the Renegade and after a very brief splash screen, the screen went blank
- I tried this several times.
I eventually:
- Flashed a Libre pre-installed OS to the uSD card using Etcher
- Booted the OS on the Renegade
- Git cloned and compiled libretech-flash-tool
- Used the flash tool to flash a bootloader on the eMMC (not sure if this was necessary)
- Used wget to download the desired OS image
- Used dd to flash the OS image to the eMMC
That worked fine and the Renegade is now happily running the Libre pre-installed Ubuntu server from the eMMC card.
