Hardware Preparation

You need to prepare the following hardware before proceeding with the installation.

Installation/Boot

  • Radxa ROCK Pi E

Go to the Resource Download page to download the corresponding Loader file.

Download System Image

On your PC, visit the Resource Download page and find the official OS image.

After downloading, extract the system image file. The resulting *.img file is the system image to be flashed to the eMMC.

Enter Maskrom Mode

We need to put ROCK Pi E into Maskrom mode, then install the system to the onboard eMMC using this mode.

When the board has no system boot media (i.e., no microSD card is inserted in the microSD slot), the system will automatically enter Maskrom mode.

The specific steps are as follows:

  1. Before powering on the ROCK Pi E, use USB-to-DuPont cable to connect ROCK Pi E and PC
Pin FunctionConnection
ROCK Pi E : GND (Pin14)Connect to GND pin of USB cable
ROCK Pi E : USB20DM (Pin16)Connect to Data- pin of USB cable
ROCK Pi E : USB20DP (Pin18)Connect to Data+ pin of USB cable
  1. After successful connection, power on the board with a power adapter
tip

If the onboard eMMC has a system installed, short the Maskrom solder pads on the back of the board before powering on to enter Maskrom mode.

Using RKDevTool

When the device enters Maskrom mode, RKDevTool will automatically detect it. If the device is not detected, follow the steps to enter Maskrom mode again.
