ROCK Pi supports maskrom mode, which is a special running mode the CPU is waiting for command from USB OTG port. The PC tool we use to communicate with ROCK Pi in maskrom mode is rkdevelop tool, an open source tool by Rockchip.

To build rkdeveloptool on a debain based Linux distribution, follow the instruction below:

Install build dependecy:

 sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf

Clone the source code and build:

 git clone
 cd rkdeveloptool
 autoreconf -i

Now you have rkdeveloptool executable at the current directory.

 sudo cp rkdeveloptool /usr/local/bin/

Boot the board to maskrom mode

To boot ROCK Pi into maskrom mode is simple, just remove any bootable storage media, remove microSD card, remove eMMC module.
