Using RKDevTool​

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.

Entering Maskrom Mode​

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

Required Equipment​

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

Entering the 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.
