Linux
Rockchip provides the tools of upgrading under Linux(closed source) since Android 4.4. The initial RE work of the Rockchip bootloader updating protocol is by naobsd and improved by some others in rkflashtool, linuxerwang made the GUI version of the rkflashtool called rkflashkit. Note: both rkflashtool and rkflashkit can not flash the rock/update.img and can only flash in the rock/bootloader mode, not rock/mask rom mode because the rock/mask rom updating protocol is not RE yet. If you are interested in RE the protocol, ping naobad at #radxa. Since the rock/bootloader remains unchanged for a long time, it's enough for normal usage.
Flash update.img
Download the rockchip linux upgrade tool here. Unzip it, you will get upgrade_tool, it's binary executable file under linux.
Let the board go to rock/recovery mode, and run the following command to flash the rock/update.img:
sudo ./upgrade_tool uf /path/to/update.img #(UF Upgrade Flash)
If you have error with the upgrading, you can low level format the nand flash first with following command:
sudo ./upgrade_tool lf #(LF Lowlevel Format)
There are other command of the upgrade_tool, such as:
UL: upgrade the loader EF: erease the nand flash
Flash by partitions with GUI
You can download the prebuilt rkflashkit here or build it yourself with the following command:
git clone https://github.com/linuxerwang/rkflashkit cd rkflashkit ./waf debian
Install it with the following command
sudo apt-get install python-gtk2 sudo dpkg -i rkflashkit_0.1.1_all.deb
Run it with the following command
sudo rkflashkit
You can see the interface like this:
