Rockpi4/install

Installation

Choose and install an operation system on your ROCK Pi 4. To appropriately follow this installation guide you will need to:

• Choose an installation method
• Download necessary files
• Choose host machine
• Follow flashing instructions

Methods of Installation

In most cases, you will be presented with two options when installing your new operating system onto your ROCK Pi 4:

• eMMC USB upgrade Method
  • The firmware will be downloaded from the USB to the ROCK Pi 4 on board eMMC storage
• Running on SD Card Method
  • The firmware will be written on a SD Card that will lately be inserted onto ROCK Pi 4.

Each Method has its own benefits and requires different levels of experience.

eMMC USB upgrade Method

Rockusb is a custom USB protocal from Rockchip supported by ROCK Pi 4 and can be used for firmware installation(USB to eMMC). This method applies to advanced users who are most familiar with command line tools or modified/custom source code and need to download such updates to the board for testing/execution.

This method requires the following hardware:

• ROCK Pi 4 board with power supply
• Host machine (Linux/Mac)
• USB Type-A to Type-A cable
• USB serial to TTL cable(not required to perform flash)
• USB Mouse and/or keyboard (not required to perform flash)
• HDMI Monitor with full size HDMI cable (not required to perform flash)
• Ethernet cable (not required to perform flash)

Choose host machine

• Linux

Step 1: Make sure rkdeveloptool is set up on host computer

To build rkdeveloptool on a debain based Linux distribution, follow the instruction below:

Install build dependecy:

 sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf

Clone the source code and build:

 git clone https://github.com/rockchip-linux/rkdeveloptool
 cd rkdeveloptool
 autoreconf -i
 ./configure
 make

Now you have rkdeveloptool executable at the current directory.

 sudo cp rkdeveloptool /usr/local/bin/

Step 2: Make sure upgrade_tool is set up on host computer

Go to the [Download Page ] to get your upgrade_tool.

Step 3: Download all necessary images

For ROCK Pi 4, there are two formats of system images. They have already been distinguished by name, one is xxx-gpt.img and the other is xxx-rkupdate.img. They have different method for flashing.

When you choose the format of xxx-gpt.img, you also need rk3399_loader_xxx.bin and the tool, rkdeveloptool.

When you choose the format of xxx-rkupdate.img, you also need the tool, upgrade_tool.

Step 4: Boot device into maskrom mode

1. Insert eMMC Module into eMMC to uSD card converter board. Insert the converter board into uSD Card Reader, which connects to host Linux OS.
2. Use the command to erase the eMMC device

 sudo dd if=/dev/zero of=/dev/sdx bs=1M count=100

3. Insert the eMMC onto the socket on board.
4. Power on ROCK Pi 4.
5. Plug the ROCK Pi 4 to Linux Desktop with USB type A to type A cable. On the host PC, command, lsusb, should show the following VID/PID if the board is in maskrom mode: Bus 003 Device 061: ID 2207:0011

Step 6: Flash images onto ROCK Pi 4 eMMC and reboot

When you choose the format of xxx-gpt.img, you should follow the steps:

 rkdeveloptool db rk3399_loader_xxx.bin
 rkdeveloptool wl 0 system.img
 rkdeveloptool rd

When you choose the format of xxx-rkupdate.img, you should follow the steps:

 upgrade_tool uf xxx-rkupdate.img

Now you reboot the new image on eMMC.

• Mac

Running on SD Card Method

Running on SD card method allows you to place a microSD card into a ROCK Pi 4 to automatically boot and run.

This method required the following hardware

• ROCK Pi 4 board with power supply
• Host machine (Linux/Mac/Windows)
• MicroSD card with 8GB or larger of storage
• USB Mouse and/or keyboard
• HDMI Monitor with full size HDMI cable
• Ethernet cable

Choose host machine

• Linux/Mac/Windows
