Linux & Android 燒錄方法 (Linux & Android 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.

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(Method 2)：Update image through SD-Card 

Download SD DiskTool

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
