Android 燒錄方法 (Android Flash eMMC Method) 

1. 請先準備一條 mirco USB 線材 和 Debug Cable 

 mirco USB 

Debug Cable 

2. 插入 RSB-3710 的OTG port 

連接 Debug cable 

2. 設定終端機(Set Debug Terminal) 

Debug 串口調試 (Debug port Setting)

以 Tera Term  为例介绍如何使用串口调试功能

   Baud Rate波特率：115200
   Data 数据位：8
   Parity 奇偶校验：无
   Stop 停止位：1
   Flow Control流控：无

Tera Term Tool 

Note:

Check the Sriel port in Device Manager (查看PC端的串口号)：

if you can not identify the Serial device , please check your serial driver. 

3.打開燒錄軟體

4. 打開電源 

5. 在終端機上可看到Debug 訊息, 按下"Ctrl + C" 組合鍵. 進入u-boot 

6. 在u-boot ,輸入"loader"   可進入燒錄模式 , Android tool 會同時顯示 "Found One MASKROM Device " 

7. 在RKDevTool 按下 "Run"  ,可進行燒錄.

系统的基本使用(Linux System Basic Operating Method)

Display Setting (RSB-3710)

In u-boot:

=> setenv prmry_screen lvds-g070vw01

=> setenv extend_screen hdmi-default

=> saveenv

=> reset

In Linux:

~# fw_setenv prmry_screen lvds-g070vw01

~# reboot

Modify LVDS backlight PWM: (Defaul is 20KHz, New version BSP support to modify the PWM clock in u-boot from 200~20KHz)

In u-boot:

=> setenv lvds_pwm_clock 10000 (Set PWM clock to 10KHz)

In Linux:

~# fw_setenv lvds_pwm_clock 10000 (Set PWM clock to 10KHz)

~# reboot

Check PWM duty sysle in Linux:

~# cat /sys/kernel/debug/pwm
