Step1 請先準備一條 USB 線材 和 Debug Cable
USB 線材
<img _fck_mw_filename="RSB-4810 USB both.png" _fck_mw_origimgheight="241" _fck_mw_origimgwidth="405" alt="RTENOTITLE" src="/wiki/images/0/0c/RSB-4810_USB_both.png" style="vertical-align:middle;" title="RTENOTITLE" />
Debug Cable
<img _fck_mw_filename="RSB-3710 debug cable 2021-11-02 144650.jpg" _fck_mw_origimgheight="339" _fck_mw_origimgwidth="508" alt="RTENOTITLE" src="/wiki/images/8/8d/RSB-3710_debug_cable_2021-11-02_144650.jpg" style="vertical-align:middle;" title="RTENOTITLE" />
Step2 Double click DriverInstall.
<img _fck_mw_filename="Driver Assitant v5.11.png" _fck_mw_origimgheight="136" _fck_mw_origimgwidth="434" alt="RTENOTITLE" src="/wiki/images/3/32/Driver_Assitant_v5.11.png" style="vertical-align:middle;" title="RTENOTITLE" />
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 _fck_mw_filename="RSB-4810 J4 setting.png" _fck_mw_origimgheight="222" _fck_mw_origimgwidth="416" alt="RTENOTITLE" src="/wiki/images/0/08/RSB-4810_J4_setting.png" style="vertical-align:middle;" title="RTENOTITLE" />
b ) Connect one part of the USB cable to the USB port below and the other end to the computer.
<img _fck_mw_filename="RSB-4810 USB conjoint.png" _fck_mw_origimgheight="340" _fck_mw_origimgwidth="414" alt="RTENOTITLE" src="/wiki/images/1/19/RSB-4810_USB_conjoint.png" style="vertical-align:middle;" title="RTENOTITLE" />
c ) Jump the J1 jumper cap to Pin1-Pin2, then switch on the 12V power supply.
<img _fck_mw_filename="RSB-4810 J1 setting.png" _fck_mw_origimgheight="299" _fck_mw_origimgwidth="415" alt="RTENOTITLE" src="/wiki/images/e/e6/RSB-4810_J1_setting.png" style="vertical-align:middle;" title="RTENOTITLE" />
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"
<img _fck_mw_filename="RSB-4810 J1 setting 1.png" _fck_mw_origimgheight="239" _fck_mw_origimgwidth="417" alt="RTENOTITLE" src="/wiki/images/9/9e/RSB-4810_J1_setting_1.png" style="vertical-align:middle;" title="RTENOTITLE" />
<img _fck_mw_filename="RSB-4810 burning.png" _fck_mw_origimgheight="208" _fck_mw_origimgwidth="417" alt="RTENOTITLE" src="/wiki/images/b/b3/RSB-4810_burning.png" style="vertical-align:middle;" title="RTENOTITLE" />
f ) Just wait patiently for the burning to finish.
<img _fck_mw_filename="RSB-4810 RKTool success.png" _fck_mw_origimgheight="208" _fck_mw_origimgwidth="414" alt="RTENOTITLE" src="/wiki/images/5/5d/RSB-4810_RKTool_success.png" style="vertical-align:middle;" title="RTENOTITLE" />
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 _fck_mw_filename="RK3288 upgrade Loader MASHROM.png" _fck_mw_origimgheight="466" _fck_mw_origimgwidth="915" alt="RTENOTITLE" src="/wiki/images/4/4a/RK3288_upgrade_Loader_MASHROM.png" style="vertical-align:middle;" title="RTENOTITLE" />
Select the image path.

Finish the update
