Libre Computer eMMC Flash Tool (LEFT) for Rapid OS Deployment

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.
