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. |
||||
|
||||
for more detail about the rkdeveloptool. please read the usage. |
||||
|
||||
rkdeveloptool -h |
||||
|
||||
use rkdeveloptool wl command to write lba. BeginSec is the lba on device |
||||
you want to write. |
||||
|
||||
sudo rkdeveloptool wl <BeginSec> <File> |
||||
|
||||
to flash U-Boot image use below command. U-Boot binary is made by mkimage. |
||||
see doc/README.rockchip for more detail about how to get U-Boot binary. |
||||
|
||||
sudo rkdeveloptool wl 64 <U-Boot binary> |
||||
|
||||
There are plenty of Rockusb command. but wl(write lba) and |
||||
rd(reboot) command. These two command can let people flash |
||||
image to device. |
||||
|
||||
To do |
||||
----- |
||||
* Fully support Rockusb protocol |
