Introduction

This page describes how to flash the image file from the host to the development board's eMMC, via the dual male usb data cable.

Please choose the right way according to the host OS and the type of image file .

Before Start

What you need:

  • AIO-3399J MainBoard

  • Image file

  • Host PC

  • Dual male usb data cable

There are two types of image file:

  • Packed image, often known as update.img, which contains the bootloader, parameter and all the partition image files. It is used for firmware release.

  • Non-packed image, like kernel.img, boot.img, recovery.img, etc, which are created during development.

You can download firmwares on compiled update.img, uncompress them after download. Or you can compile firmware by yourself according to Build Android .

Supported host OS:

  • Windows XP (32/64bit

  • Windows 7 (32/64bit)

  • Windows 8 (32/64bit)

  • Linux (32/64bit)

Windows

We used to need two utilities to flash rockchip image file:

  • RKBatchTool, used to flash update.img

  • RKDevelopTool, used to flash partition image file separately.

After that, Rockchip release new tool: AndroidTool. It is based on RKDevelopTool, but adds flashing support for update.img. So you can use this tool instead.

Before using the flashing utility, you need to install RK USB driver. If the driver is already installed, you can skip to next step.

Install RK USB Driver

Download Release_DriverAssistant.zip, uncompress it, then run DriverInstall.exe inside.

In order to use new driver for all the rockchip devices, please select "驱动卸载"(Driver uninstall), then "驱动安装"(Driver install).

Connect Device

AIO-3399J

There are two ways to switch the device to upgrade mode.

  • The first one, device is cut off all the power sources, such as power adapter and Dual male usb data cable connection:

  1. 1.Keep usb cable port connected with host PC.

  2. 2.Another usb cable port connect to Dual USB3.0 port above of the device.(Engineering prototype: connect the Dual USB3.0 port below )

  3. 3.Press and hold RECOVERY key.

  4. 4.After around two seconds, release RECOVERY key.

  • The other way:

  1. 1.Keep usb cable port connected with host PC.

  2. 2.Another usb cable port connect to Dual USB3.0 port above of the device.(Engineering prototype: connect the Dual USB3.0 port below )

  3. 3.Press and hold RECOVERY key.

  4. 4.Shortly press RESET key.

  5. 5.After around two seconds, release RECOVERY key.

The host will prompt to have new device detected and configured. Open the Device Management, you'll find a new device name "Rockusb Device", as shown below. Return to previous step to reinstall driver if it is not shown.

Download AndroidTool.(Android8.1 need AndroidTool_Release_v2.54 or higher version) Uncompress it and change to directory AndroidTool_Release_v2.38.

AndroidTool defaults to display in Chinese. We need to change it to English. Open config.ini with an text editor (like notepad). The starting lines are:

#选择工具语言:Selected=1(Chinese);Selected=2(English)
[Language]
Kinds=2
Selected=1
LangPath=Language\

Change "Selected=1" to "Selected=2", and save. From now on,  AndroidTool will display in English.

Now, run AndroidTool.exe: (Note: If using Windows 7/8, you'll need to right click it, select to run it as Administrator)

Flash update.img

Steps of flashing update.img:

  1. Switch to "Upgrade Firmware" tab page.

  2. Click "Firmware" button and open the image file. Detail information of the image file, like version and chip, is shown.

  3. Click "Upgrade" button to start flash.

  4. If upgrade fails, please try "LowerFormat" in the "Download Image" tab page first, then try again.

WARNING: If you flash firmware laoder different version of the original machine, please click "Erase Flash" before upgrading the firmware.

Steps of flashing partition images:

  1. Switch to "Download Image" tab page.

  2. Check the partitions you want.

  3. Make sure the image file's path is correct. Click the rightmost empty table cell to select new path if needed.

  4. Click "Run" button to start flashing. Device will reboot automatically when finish.

Linux

Rockchip provides a command line utility named "upgrade_tool" under Linux, which support flashing of both update.img and partition images.

We have two choices with regard to open source tools:

Both of them only support flashing partition images, not update.img. rkflashtool is a command line tool, and flashkit has a nice and easy to use GUI with command line support lately added. We only introduce rkflashkit below.

There is no need to install device driver. Just connect the device and host as described in the Windows section.

upgrade_tool

Download Linux_Upgrade_Tool,(Android8.1 need Linux_Upgrade_Tool_for_android8.1) and install it to host filesystem:

   unzip Linux_Upgrade_Tool_v1.24.zip
   cd Linux_UpgradeTool_v1.24
   sudo mv upgrade_tool /usr/local/bin
   sudo chown root:root /usr/local/bin/upgrade_tool

NOTE: If you are prompted with the following error:

   upgrade_tool: error while loading shared libraries: libudev.so.1: cannot open shared object file: No such file or directory

You can use the following command to solve:

   sudo ln -sf /lib/i386-linux-gnu/libudev.so.0 /lib/i386-linux-gnu/libudev.so.1

Flash update.img:

   sudo upgrade_tool uf update.img

Flash partition images

   sudo upgrade_tool di -b /path/to/boot.img
   sudo upgrade_tool di -k /path/to/kernel.img
   sudo upgrade_tool di -s /path/to/system.img
   sudo upgrade_tool di -r /path/to/recovery.img
   sudo upgrade_tool di -m /path/to/misc.img
   sudo upgrade_tool di resource /path/to/resource.img
   sudo upgrade_tool di -p paramater   #flash parameter
   sudo upgrade_tool ul bootloader.bin #flash bootloader
   sudo upgrade_tool di trust /path/to/trust.img #flash trust

If errors occur due to flash problem, you can try to low format, or erase the flash:

   upgrade_tool lf update.img   # low format flash
   upgrade_tool ef update.img   # erase flash

rkflashkit

Install:

   sudo apt-get install build-essential fakeroot 
   git clone https://github.com/linuxerwang/rkflashkit
   cd rkflashkit
   ./waf debian
   sudo apt-get install python-gtk2
   sudo dpkg -i rkflashkit_0.1.4_all.deb
  • GUI:

   sudo rkflashkit
rkflashkit
  • Command line:

$ rkflashkit --help
Usage:  [args] [ [args]...]

part                              List partition
flash @    Flash partition with image file
cmp @      Compare partition with image file
backup @   Backup partition to image file
erase  @               Erase partition
reboot                            Reboot device

For example, flash device with boot.img and kernel.img, then reboot:

sudo rkflashkit flash @boot boot.img @kernel.img kernel.img reboot

See the example above, which is really handy to flash multiple images then reboot device in one command, especially good for developers who will compile and flash kernel again and again.
