Clear eMMC or SPI Flash

Enter to Maskrom Mode​

  • Remove the microSD card and power cable
  • Press and hold the Maskrom button
  • Connect the USB of the PC host via USB-A to USB-C cable, and if a device is detected on the PC side, it will enter into Maskrom mode (the OTG interface of Radxa ROCK 5 ITX is TYPE-C, so you can connect the host to the motherboard that enters into Maskrom through the USB-C to USB-A cable for communication).
