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)

Go to the Downloads to get your system

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: Downloads all necessary images

For ROCK Pi 4, there are two version of system images, Android and Debian. The system image names have the specified words, like android and debian. And all the system images names are marked with xxx_gpt.img.

Step 3: 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 4: 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 xxx_gpt..img
 $ rkdeveloptool rd

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

Go to the Downloads to get your system

Choose host machine

The host machine type includes Linux, Mac, Windows. But this solution doesn't support flashing images in xxx-rkupdate.img format.

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

Download the flash tool, etcher, from Downloads. Choose the right version for your host operation system. Here we operate on host Ubuntu 16.04.

After download the package, unpack it.

Step 2: Downloads all necessary images

For ROCK Pi 4, there are two version of system images, Android and Debian. The system image names have the specified words, like android and debian. And all the system images names are marked with xxx_gpt.img.

Step 3: Flash the image into uSD Card

1. Insert the uSD Card into uSD Card Reader, which connects to host computer.

2. Run the application, for example, by executing the command on Ubuntu 16.04:

 $ /bin/bash etcher-etcher-electron-1.4.5-x86_64.AppImage

3. In the etcher window, we click button Select image.

4. In the etcher window, we click button Select Drive.

5. In the etcher window, we click button Flash.

6. In the etcher window, it shows us Flash Complete!

7. Insert uSD Card into the socket on board.

8. Connect the ROCK Pi 4 to your display with the HDMI cable. Ensure that the source for the display is switched to the HDMI port you are using.

9. Connect the USB keyboard and mouse.

10. Connect the power supply to the ROCK Pi 4. The board will begin to immediately.
