Install the image to eMMC module with USB to eMMC Reader

This guide describes how to write images to eMMC module and erase eMMC module for ROCK 5 serial boards.

Available ROCK 5 boards:

ROCK 5B

Option 1: Write one system image to eMMC module

In part one let's focus on writing one system image to eMMC module. Here we test it with ROCK 5B board.

Step one: Requirements

ROCK 5B board with power supply
one eMMC module, larger than 8GB
one USB to eMMC reader
one PC/laptop running Windows or Linux or MacOS

Step two: Download necessary tools and image

Etcher is the tool we use to write image. Download the right Etcher for your PC from ROCK 5 Downloads page and install it. Check Etcher website for more info about Etcher.
Choose the image you want to install from ROCK 5 Downloads page.

Here we use the following image for writing.

 rock-5b-debian-bullseye-xfce4-arm64-20220420-0439-gpt.img.xz

Step three: Write the image to eMMC module

Insert the eMMC module into USB to eMMC reader, which connects to host computer.

Run the application. For example double click balenaEtcher-1.7.9-x64.AppImage on Ubuntu 20.04:

In the etcher window, we click button Select image.

In the etcher window, we click button Select Drive.

In the etcher window, we click button Flash.

In the etcher window, it shows us Flash Complete!

Done! Now you have successfully installed the OS image on eMMC module.

Option 2: Erase eMMC module

When eMMC module is written with Android (or Linux) images before, now we change to Linux( or Android). It's recommended that you erase eMMC module first. Then write the target images.

Option 3: Write bootloader only to eMMC module

In part three let's take a look know to write U-Boot images to eMMC module. We have prebuilt u-boot images built via rockchip-bsp SDK. They're idbloader.img and u-boot.itb.

On Linux PC:

$ sudo dd  if=./idbloader.img  of=/dev/sdX  seek=64
$ sudo dd  if=./u-boot.itb   of=/dev/sdX  seek=16384

On Mac PC:

% sudo dd  if=./idbloader.img  of=/dev/diskX  seek=64
% sudo dd  if=./u-boot.itb  of=/dev/diskX  seek=16384
