RKFlashTool

rkflashtool is a tool for managing rockchip socs via the rockusb protocol.
It was born as a fork of https://github.com/linux-rockchip/rkflashtool, with the aim of making the tool as user friendly as possible.

!!! WARNING !!!

I'm not a Rockchip employee, so this software is the result of personal studies and many tests.
Rockchip boards are easily recoverable, but use at your own risk in any case.

Features

• install/upgrade bootloader
• full dump of internal memory
• flash raw image on internal memory
• read/write/erase partitions (for now only with rkparam method)
• read/write/erase LBA

You need to know before start

Before you start, you need to know a couple of concepts

RockUSB Rockusb is the usb communication protocol implemented in most of the official rockchip firmwares.

MaskROM It's a minimal firmware that is booted by the soc when it's unable to load a full bootloader. It's capable of loading a complete loader and is the mode required for flash/dump operations.

DDRBIN It's the part of the proprietary bootloader that takes care of configuring and activating the ddr memory.

USBPLUG It's the part of the proprietary bootloader that takes care of activating the internal memory and other components, and that takes care of managing the rockusb protocol.

Tested with

• Rockchip 3128 android tv box
• Rockchip 322x android tv box
