Install System to eMMC (Applicable to V1.5)

This section tutorial mainly introduces how to install the system to the on-chip eMMC of the Radxa ROCK Pi S V1.5.

tip

ROCK Pi S V1.5 is based on the V1.3 version, and it has added the on-chip eMMC, so you can directly boot the system through eMMC without using a MicroSD card.

Hardware Preparation

Prepare the following hardware to complete the system installation and boot process.

For Installation/Booting

• Development Board: Radxa ROCK Pi S V1.5
• Power Supply: Use a Type-C to Type-A data line to connect to the PC for power supply and data transmission

Installing the OS

Installing the OS will format the eMMC. Please back up any important data before proceeding.

File Downloads

Download Loader File

Visit the Downloads page to download the corresponding Loader file.

Download System Image

On your PC, go to the Downloads 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.

Entering Maskrom Mode

We need to put the ROCK Pi S into Maskrom mode to install the system on the eMMC.

tip

The MicroSD card must be removed for the ROCK Pi S to enter Maskrom mode. Otherwise, it will boot directly from the MicroSD card instead of entering Maskrom mode.

① : MicroSD card slot --> Ensure the MicroSD card is removed

② : Maskrom button

③ : Type-C port

Follow these steps:

1. With the ROCK Pi S powered off, press and hold the Maskrom button
2. Connect the development board to your PC using a Type-C to Type-A cable (Type-C end to the board, Type-A end to the PC)
3. Release the Maskrom button

Using RKDevTool

Once the device is in Maskrom mode, RKDevTool should automatically detect it. If the device isn't recognized, please repeat the steps to enter Maskrom mode.

Checking Maskrom Device

Windows

Open RKDevTool to view the recognized device information:

Linux/MacOS

Use the rkdeveloptool ld command to view recognized device information:

Linux/macOS-host$

sudo rkdeveloptool ld

Example output showing a Maskrom device is detected:

Linux/macOS-host$

DevNo=1	Vid=0x2207,Pid=0x330e,LocationID=101	Maskrom

Installing System Image

Windows

In the RKDevTool software, perform the following steps:

• ① : Select the Loader file
• ② : Select the system image
• ③ : Choose eMMC as the system storage medium
• ④ : Check the Write by Address option
• ⑤ : Start the operation (write Loader and system)
• ⑥ : Operation feedback information

Linux/MacOS

Open your system terminal or command line and perform the following steps.

• Run Loader

Replace xxx.bin with the actual Loader filename you downloaded.

Linux/macOS-host$

sudo rkdeveloptool db xxx.bin

On successful download, the terminal will display output similar to:

Linux/macOS-host$

Downloading bootloader succeeded.

• Install System Image

Replace xxx.img with the actual system image filename you downloaded.

Linux/macOS-host$

sudo rkdeveloptool wl 0 xxx.img

• Reboot the Device

Linux/macOS-host$

sudo rkdeveloptool rd
