Step1 請先準備一條 USB 線材 和 Debug Cable
USB 線材

Debug Cable

Step2 Double click DriverInstall.
<img src="/wiki/images/3/32/Driver_Assitant_v5.11.png" _fck_mw_filename="Driver Assitant v5.11.png" _fck_mw_origimgwidth="434" _fck_mw_origimgheight="136" alt="RTENOTITLE" title="RTENOTITLE" style="vertical-align:middle;" />
Step3 Enter into MASKROM mode .
There are two ways to enter MASKROM .
1. Hardware way to enter MASKROM
a ) Connect jumper cap J4 to Pin1 - Pin2(set USB-otg mode).
Note:Default jumper cap J4 Connect Pin2-Pin3 (Set USB-host mode)
<img src="/wiki/images/0/08/RSB-4810_J4_setting.png" _fck_mw_filename="RSB-4810 J4 setting.png" _fck_mw_origimgwidth="416" _fck_mw_origimgheight="222" alt="RTENOTITLE" title="RTENOTITLE" style="vertical-align:middle;" />
b ) Connect one part of the USB cable to the USB port below and the other end to the computer.
<img src="/wiki/images/1/19/RSB-4810_USB_conjoint.png" _fck_mw_filename="RSB-4810 USB conjoint.png" _fck_mw_origimgwidth="414" _fck_mw_origimgheight="340" alt="RTENOTITLE" title="RTENOTITLE" style="vertical-align:middle;" />
c ) Jump the J1 jumper cap to Pin1-Pin2, then switch on the 12V power supply.
<img src="/wiki/images/e/e6/RSB-4810_J1_setting.png" _fck_mw_filename="RSB-4810 J1 setting.png" _fck_mw_origimgwidth="415" _fck_mw_origimgheight="299" alt="RTENOTITLE" title="RTENOTITLE" style="vertical-align:middle;" />
d ) Then the burning tool will appear: a MASKROM word found.
Note:Suspend or shut down the virtual machine during this process; otherwise, the pop-up information may affect the burning results.

e ) Jump the J1 jumper cap back to Pin2-Pin3 and click "Execute"

f ) Just wait patiently for the burning to finish.

2. Software way to enter MASKROM
When the device boot up to android or debian, you can use ADB or Debug console, send command "reboot loader" .
Or Press "ctrl + c" key when booting into uboot, until get the following information on debug console :
Android 7.1:
Hit any key to stop autoboot: 0 rkboot # <INTERRUPT> rkboot # loader
Debian 10.x:
Hit any key to stop autoboot: 0 rkboot # <INTERRUPT> rkboot # rbrom

Click "Advantech Function" , then "Enter MASHROM" button to enter MASHROM mode .
<img src="/wiki/images/4/4a/RK3288_upgrade_Loader_MASHROM.png" _fck_mw_filename="RK3288 upgrade Loader MASHROM.png" _fck_mw_origimgwidth="915" _fck_mw_origimgheight="466" alt="RTENOTITLE" title="RTENOTITLE" style="vertical-align:middle;" />
Step4 Select the image path.

Step5 Finish the update
