Linux/MacOS

On such platforms, we can use the Amlogic boot tool to load binaries. First make sure that the python environment is installed, then run the following command in a new terminal:

MacOS

brew install python lsusb libusb
pip3 install pyamlboot

Similar to the Windows platform, you can also install fastboot using nexus-tools by running the following commands in the terminal, or skip this step if you don't need these:

bash <(curl -s https://raw.githubusercontent.com/corbindavenport/nexus-tools/master/install.sh)

Linux

sudo apt update
sudo apt install python3-pip
sudo pip3 install pyamlboot

Similar to the Windows platform, you can also install fastboot using nexus-tools by running the following commands in the terminal, or skip this step if you don't need these:

bash <(curl -s https://raw.githubusercontent.com/corbindavenport/nexus-tools/master/install.sh)

Flash the firmware

Windows

Once the tool detects the Maskrom mode, you can click the Select button to select the radxa-zero2-2pro-erase-emmc.bin file and then click the Run button to load it:

The results of the run are shown above.

After this, your computer will recognize the Radxa ZERO 2 PRO as a USB storage device, and you can simply flash the system image to it as described in the Operating System Installation Guide and boot up normally.

Linux/MacOS

Under this platform, you can use the boot-g12.py utility.

Run the following command for loading the firmware:

boot-g12.py radxa-zero2-2pro-erase-emmc.bin

On Linux platforms, you will also need to add sudo to obtain permissions:

sudo boot-g12.py radxa-zero2-2pro-erase-emmc.bin

After this, your computer will recognize the Radxa ZERO 2 PRO as a USB storage device, and you can simply flash the system image to it as described in the Operating System Installation Guide and boot up normally.
