Linux 燒錄方法 (Linux Flash eMMC Method)

NOTE :

This way only support Linux(Debian9) upgrade to Linux(Debian9) 、 Android6.0 upgrade to Android6.0 or Android8.1 upgrade to Android8.1.

If the device is in Android, you want to upgrade to Linux(Debian9), please use Android Tool.

方法一：Update through Android Tool

Step0: Need to use Micro USB to connect with RSB-4680 OTG port, and other Type-A USB to connect with your PC

Step1: Double click DriverInstall.exe .

Step2: Enter into MASKROM mode .

There are two ways to enter MASKROM .

1. Hardware way to enter MASKROM

（1）Connect PIN2-PIN1 of CN19 to Disable eMMC，reboot device to enter MASKROM mode.

（2）After device enter into MASKROM mode，then connect PIN2-PIN3 of CN19 to Enable eMMC.

RSB-4680 Connector Layout :

RSB-4680 CN19 PIN define :

2. Software way to enter MASKROM

When the device boot up to debian, you can use Terminal or Debug port to input the following command :

sudo reboot loader

Click "Advantech Function" , then "Enter MASHROM" button to enter MASHROM mode .

Step3: Select the image path .

Step4 : Click update button to upgrade images .

Step5 : When“下載完成(Download finish )” , please unplug the Micro USB with RSB-4680 , then turn off and turn on the power again .

Step6 : Please remove the Micro USB and the poewer , then reboot the device , you will see the Debian Desktop.

方法二：Update image through SD-Card

Download SD DiskTool

https://github.com/ADVANTECH-Rockchip/linux_tools/tree/rk3288_linux_v2.0

Step 1 : Put images to AndroidTool/rockdev/image, Make sure path is correct.

Step 2 : Double click rk3328-mkupdate.bat in AndroidTool/rockdev/ .

If there is no error, you will find update.img in AndroidTool/rockdev/ .

Generate SD card

Step 1 : Insert SD card to PC， Double click SD_Firmware_Tool.exe in SDDiskTool .

Step 2 : Choose SD card .

Step 3 : Choose update.img .

Step 4 : Create SD card .

NOTE :

The capacity of SD card is at least 4GB.

Upgrade image from SD card

Step 1 : Insert SD card to device .

Step 2 : Power up or reboot device， it will boot from SD card to auto upgrade images .

Step 3 : When upgrade is finish, you will get "Doing Actions succeeded,please remove sdcard......" on screen or debug console .

Step 4 : Remove SD card， the device will auto reboot .
