Install the image to SPI Nor Flash
ROCK 5 has one SPI Flash on the board, it's useful to install the bootloader to the SPI flash for a back up booting and support other booting media that the SoC maskrom mode doesn't direct support, such as SATA, USB 3 or NVMe. This page describe how to write/install the image to the SPI flash with the tool from another PC or on the ROCK 5B board itself.
Requirement
- ROCK 5B with proper power
- Linux image for ROCK 5B, Android image is not supported yet
- SD card or eMMC module
- USB Type C cable
- Windows/linux/macOS PC
Step1: Install Tools&Drivers
Please check this guide, Install rockchip flash tools under Windows/Linux/MacOS PC. The PC tools we use to communicate with ROCK 5 in Maskrom mode are the rkdeveloptool and RKDevTool. We use the rkdeveloptool in Linux/macOS and the RKDevTool under Windows.
Step2: Get RK3588 loader and U-Boot images
For ROCK 5B
- Download the loader image from:
- RK3588 loader - USB flashing helper
- Download the latest SPI image from:
- release version with u-boot serial console disabled(Recommend)
- debug version with u-boot serial console enabled(Use it when you need to troubleshoot booting issue)
Step3: Boot the board to Maskrom mode
To boot ROCK 5B to Maskrom mode is simple:
- Power off the board.
- Remove bootable device like MicroSD card, eMMC module, etc.
- Press the golden (or silver on some board revisions) button and hold it.
- Plug the USB-A to Type-C cable to ROCK 5B Type-C port, the other side to PC.
- Release the golded button.
- Check usb device
- For macOS host: lsusb result: Bus 002 Device 032: ID 2207:350b Fuzhou Rockchip Electronics Co., Ltd. Composite Device
- For Linux host: lsusb result: Bus 001 Device 112: ID 2207:350b Fuzhou Rockchip Electronics Company
- For Windows host: Open RKDevTool and you would see the device is in Found One MASKROM Device
Step4: Write U-Boot images to SPI Nor Flash or erase SPI Nor Flash
Option 1: Operate on ROCK 5B
Boot your ROCK 5B with Linux running on SD card or eMMC module:
Make sure the SPI flash is available:
ls /dev/mtdblk*
sudo dd if=zero.img of=/dev/mtdblock0 sudo dd if=rock-5b-spi-image-g49da44e116d.img of=/dev/mtdblock0 sync
Get zero.img from here.
Option 2: Flash with Linux PC/Mac
On your PC or Mac, run the rkdeveloptool
sudo rkdeveloptool ld DevNo=1 Vid=0x2207,Pid=0x350b,LocationID=106 Maskrom
This will load the loader (flash helper, downloaded from Step2) to run on ROCK 5B and init the ram and prepare the flashing environment etc.
sudo rkdeveloptool db /path/to/rk3588_spl_loader_v1.08.111.bin # will output: Downloading bootloader succeeded.
Next, write SPI image from PC/Mac to ROCK 5B SPI flash
You can use the image download from Step 2.
sudo rkdeveloptool wl 0 rock-5b-spi-image-g49da44e116d.img Write LBA from file (100%)
Reboot the device
rkdeveloptool rd
now, the device should boot on SPI Nor Flash. And the blue led is on.
Option 3: Flash with Windows PC
Double click the RKDevTool.exe and you will see the following interface: Double click the RKDevTool.exe and you will see the following interface:
Step 1: comfirm that ROCK 5B is in Maskrom mode

Boot your ROCK 5B with Linux running on SD card or eMMC module:
Make sure the SPI flash is available:
ls /dev/mtdblk*
sudo dd if=/dev/zero of=/dev/mtdblock0 sync
Option 2: Erase with Linux PC/Mac
Please notice that when you want to erase SPI Nor Flash, fire these commands. If you don't have zero.img, download this one please. zero.img And extract it.
rkdeveloptool db rk3588_spl_loader_v1.08.111.bin rkdeveloptool wl 0 zero.img rkdeveloptool rd
Option3: Erase with Windows PC
Before Erasing, please confirm that ROCK 5B is in Maskrom mode
Step 1: Download
Choose the "Advanced features" button, then select rk3588_spl_loader_v1.08.111.bin, next click the "Download" button
