Hardware Connection​

Required Equipment​

  • One USB Type-A to Type-C cable
  • A pin or toothpick
  • 12V/2A DC power adapter (DC5525)

Entering Maskrom Mode​

tip

Maskrom mode is the "hardware first-aid kit" for embedded devices, enabling device recovery by directly interfacing with the chip's low-level hardware.

Maskrom mode is a built-in low-level recovery mode in Rockchip chips, which is automatically entered when the device cannot load a valid bootloader from any boot medium (eMMC, SD card, etc.).

This mode allows rewriting the device firmware via the RockUSB protocol.

Radxa E24C has a dedicated Maskrom button. If this button is detected as pressed during system startup, the system will automatically enter Maskrom mode!

  1. Connect Radxa E24C to your PC using a USB Type-C to Type-A cable

  2. Press and hold the Maskrom button using a pin or toothpick

  3. Connect the 12V/2A DC power adapter

  4. Release the Maskrom button

Normally, the power indicator will stay lit when in Maskrom mode. If this doesn't happen, you can repeat the steps above.

Open your system terminal or command line and run the following command to check if the Maskrom device is detected.

Linux/macOS-host$
sudo rkdeveloptool ld

Expected output: One device detected

Linux/macOS-host$
DevNo=1	Vid=0x2207,Pid=0x350c,LocationID=101	Maskrom

Installing the System​
