How to install raw images to Radxa Zero eMMC

This guide describes how to install the raw images to Radxa Zero eMMC. Raw images is compared to amlupdate format image(which is a private image format). Raw images can be mount and open on host PCs. Most of the Linux images released are raw images. Currently Android images are released in amlupdate format but this may change in the future.

Requirement

  • Radxa Zero
  • USB A to C cable
  • A PC/laptop running Windows, Linux/macOS.

Windows

Now select the RZ USB disk loader.

Step 3: Use Etcher to write images to eMMC

Download the latest Etcher and install it.


Linux

For Linux, we use amlogic boot tool to download the bootloader and boot the Zero into the USB Disk mode to export the eMMC to host PC as a USB Disk, then we can use dd or other tools to write images to the USB Disk(eMMC).

Step 1: Install pyamlboot tool
   sudo apt install pip3
   sudo pip3 install pyamlboot
Step 2: Erase Android if installed(optional)

If you have Android installed on Zero before, we suggest to wipe it. Check Erase eMMC page. If you have installed Linux or other distribution already, you can skip this step.

Step 3: Boot into USB Disk mode

Press and hold the USB boot button on Zero, plug in it to PC, lsusb should see the following:

   Bus 002 Device 030: ID 1b8e:c003 Amlogic, Inc. GX-CHIP

Download the USB disk loader and run it on Zero

   wget https://dl.radxa.com/zero/images/loader/rz-udisk-loader.bin
   boot-g12.py rz-fastboot-loader.bin

It should output:

Firmware Version :

[BL2 END]

Now lsusb should show the following device:

   Bus 002 Device 013: ID 1b8e:2200 Amlogic, Inc. USB download gadget  Serial: AMLG12A-RADXA-ZERO

The Zero is in USB disk mode now, your PC should popup a new USB drive.

Step 4: Write image to eMMC

You can use dd to write the Linux image to the eMMC of Zero now.

   sudo dd if=/path/to/image of=/dev/sdx bs=1M
   sync

Carefully Eject the Zero USB drive and unplug and plug the power, Zero should boot the new image now.

macOS (Apple Silicon/Intel)

For macOS, we use amlogic boot tool to download the bootloader and boot the Zero into the USB Disk mode to export the eMMC to mac as a USB Disk, then we can use dd or other tools to write images to the USB Disk(eMMC).

Step 1: Install pyamlboot tool
   brew install python lsusb
   pip3 install pyamlboot
Step 2: Erase Android if installed(optional)

If you have Android installed on Zero before, we suggest to wipe it. Check Erase eMMC page. If you have installed Linux or other distribution already, you can skip this step.

Step 3: Boot into USB Disk mode

Press and hold the USB boot button on Zero, plug in it to mac, lsusb should see the following:

   Bus 002 Device 030: ID 1b8e:c003 Amlogic, Inc. GX-CHIP
