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.
方法一(Method 1):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(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
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 .
