How to install raw image to Radxa Zero eMMC

This guide describes how to install the raw images to Radxa Zero eMMC. Raw image is the standard method to install Linux distro on single board computers, since they don't have standardized way to boot and initialized their hardware.

Requirement

  • Radxa Zero
  • A PC/laptop running Windows, Linux, or macOS
  • USB A to C cable or C to C cable, depending on your host
  • A supported Linux image

Windows

Please follow maskrom guide to load extracted rz-udisk-loader.bin. Google driver and nexus-tools are not required.

Your computer should detect a new storage device after the file is loaded.

You can now flash your Linux image using balenaEtcher similar to flash microSD card. Choose the newly detected device in your target drive and proceed as normal.

Once you are done flashing, unplug and replug Radxa Zero to quit maskrom mode and boot normally.
