Rockusb (Rockchip USB protocol)
|
|
=====================================================
|
|
|
|
Overview
|
|
--------
|
|
|
|
Rockusb protocol is widely used by Rockchip SoC based devices. It can
|
|
read/write info, image to/from devices. This document briefly describes how to
|
|
use Rockusb for upgrading firmware (e.g. kernel, u-boot, rootfs, etc.).
|
|
|
|
Tools
|
|
--------
|
|
There are many tools can support Rockusb protocol. rkdeveloptool
|
|
(https://github.com/rockchip-linux/rkdeveloptool) is open source,
|
|
It is maintained by Rockchip. People don't want to build from source
|
|
can download from here
|
|
(https://github.com/rockchip-linux/rkbin/blob/master/tools/rkdeveloptool)
|
|
|
|
Usage
|
|
--------
|
|
The Usage of Rockusb command is:
|
|
|
|
rockusb <USB_controller> <devtype> <dev[:part]>
|
|
|
|
e.g. rockusb 0 mmc 0
|
|
|
|
On your U-Boot console, type this command to enter rockusb mode.
|
|
On your host PC. use lsusb command. you should see a usb device
|
|
using 0x2207 as its USB verdor id.

|
|
you want to write.
|
|
|
|
sudo rkdeveloptool wl <BeginSec> <File>
|
|
|
|
to flash U-Boot image use below command. U-Boot binary is made by mkimage.

|
Current set of rkdeveloptool commands supported:
|
|
- rci: Read Chip Info
|
|
- rfi: Read Flash Id
|
|
- rd : Reset Device
|
|
- td : Test Device Ready
|
|
- rl : Read blocks using LBA
|
|
- wl : Write blocks using LBA
|
|
- wlx: Write partition
|
|
|
|
To do
|
|
-----
|
|
* Fully support Rockusb protocol
