    ROCK 3 >  Installation >   Install the image to SPI Nor Flash

Install the image to SPI Nor Flash from USB port

ROCK 3 supports Maskrom mode, which is a special operation mode for CPU to wait for USB OTG port command. The Linux/macOS PC tool we use to communicate with ROCK 3 in Maskrom mode are the rkdeveloptool and RKDevTool. We use tool rkdeveloptool in Linux/macOS and RKDevTool tool under Windows.

Available boards:

• ROCK 3A

Here we do the test on ROCK 3A.

Requirement

• ROCK 3A with SPI Nor Flash (You can find SPI Nor Flash from ROCK 3 Model A Main Board)
• Power adapter
• USB Male A to Male A cable(important) USB-C has been seen as not working, an adaptor for USB-C to USB-A has worked. See discussion.

Install Tools&Drivers

Please check this guide, Install rockchip flash tools under Windows/Linux/MacOS PC.

Boot the board to maskrom mode

To boot ROCK 3A into maskrom mode is simple:

• Power off the board
• Remove bootable devices like microSD card, eMMC module, etc
• Plug the USB Male A to Male A cable to ROCK 3A OTG port(the upper USB3.0 port), the other side to PC

• Short-circuit the following pins. See the left yellow hat.

• Power on the board
• Take off the yellow hat.
• See usb device
  • For macOS PC: lsusb result: Bus 000 Device 004: ID 2207:350a Fuzhou Rockchip Electronics Co., Ltd. Composite Device
  • For Linux PC: lsusb result: Bus 001 Device 112: ID 2207:350a Fuzhou Rockchip Electronics Company
  • For Windows: Open RKDevTool and you would see the device is in "maskrom mode".

Alternatively, if you are running Android and can access ADB, you can reboot the device to loader mode 'adb reboot bootloader' then use the rkdeveloptool to reset the device into maskrom mode 'rkdeveloptool rd 3' or Windows RKDevTool Switch button to go to maskrom mode.

Get RK356X loader and U-Boot images

• RK356X loader
• ROCK 3A idbloader
• ROCK 3A u-boot.itb

Write U-Boot images to SPI Nor Flash or erase SPI Nor Flash

Download the loader (flash helper) to init the ram and prepare the flashing environment etc.

rkdeveloptool db rk356x_spl_loader_ddr1056_v1.10.111.bin
