Rockchip rkdeveloptool

The open-source Linux/macOS flashing tool for Rockchip devices in MaskROM or Loader mode.

rkdeveloptool talks the Rockchip USB protocol to a device in MaskROM or Loader mode. It can download a loader into RAM, then read and write flash, write partitions from a GPT and reboot the device. It is the standard flashing tool on Linux and macOS.

Key points

rkdeveloptool ld lists devices and shows whether each is in Maskrom or Loader mode.
In MaskROM, first run rkdeveloptool db <loader.bin> to download the SPL loader into RAM.
Then rkdeveloptool wl 0 image.img writes a raw image from sector 0, and rkdeveloptool rd reboots.
