Flash the Image

Enter the Flashing Mode of the Development Board (Pic)

To flash the image, the development board must enter the flashing mode. The flashing modes of the Rockchip platform include LOADER mode and Maskrom mode.

  • LOADER mode is commonly used for both full image flashing and partition flashing.

  • Maskrom mode is commonly used for forcibly flashing the image after the system is damaged.

You can view the buttons in the "KICKPI - Hardware Introduction" and "Development Board Information" sections.

Operation Steps:

  1. Open the flashing tool on the Windows computer (refer to the above instructions to install RKDevTool).

  2. Connect the OTG interface of the development board to the USB interface of the computer.

  3. To enter LOADER mode, press the LOADER button and power on the board (if the motherboard is already powered on, you can press the reset button to reset it). To enter MASKROM mode, press the MASKROM button on the back of the board and power on the board (if the motherboard is already powered on, you can press the reset button to reset it).

Both LOADER and MASKROM modes support full package flashing. You can choose one mode for flashing.

  1. The Rockchip development tool should be able to recognize the LOADER device or MASKROM device. (You need to install the USB driver first to recognize the relevant devices.)
