1,install compile sunxi-tools depended-upon packages

1. sudo apt-get install libusb-1.0-0-dev

复制代码

2,get sunxi-tools new code from github:

1. git clone https://github.com/linux-sunxi/sunxi-tools.git

复制代码

3,compile sunxi-tools

1. cd sunxi-tools
   
2. make

复制代码

4,backup script.bin

1. sudo cp /boot/bananapi/script.bin /boot/bananapi/script.bak

复制代码

5,copy script.bin to current dir

1. cp /boot/bananapi/script.bin ./

复制代码

6,use bin2fex change bin to fex

1. bin2fex ./script.bin ./script.fex

复制代码

7,edit script.fex file:

1. nano script.fex

复制代码

可以看到平台配制文件，编译过这个固件的人就知道它有什么用:

1. [disp_init]
   
2. disp_init_enable = 1
   
3. disp_mode = 0
   
4. screen0_output_type = 3
   
5. screen0_output_mode = 5
   
6. screen1_output_type = 2
   
7. screen1_output_mode = 11
   
8. fb0_framebuffer_num = 2
   
9. fb0_format = 10
   
10. fb0_pixel_sequence = 0
    
11. fb0_scaler_mode_enable = 1
    
12. fb1_framebuffer_num = 2
    
13. fb1_format = 10
    
14. fb1_pixel_sequence = 0
    
15. fb1_scaler_mode_enable = 0
    
16. lcd0_backlight = 197
    
17. lcd1_backlight = 197
    
18. lcd0_bright = 50
    
19. lcd0_contrast = 50
    
20. lcd0_saturation = 57
    
21. lcd0_hue = 50
    
22. lcd1_bright = 50
    
23. lcd1_contrast = 50
    
24. lcd1_saturation = 57
    
25. lcd1_hue = 50
    
26. 
    
27. just change screen0_output_mode = 5, note , other not do any change.
    
28.

Press Ctrl + x ， Y ，Enter save and exit edit:
8,use fex2bin change fex to bin

1. fex2bin ./script.fex ./script.bin

复制代码

copy script.bin to /boot

1. sudo cp ./script.bin /boot/bananapi/

复制代码

9,reboot and make a try

1. sudo reboot

复制代码

更简单的改变设置变量的方法:
just edit uEnv.txt file to change it:

1. bootargs=enforcing=1 console=ttyS0,115200 console=tty1 root=/dev/mmcblk0p2 rootwait init=/init vmalloc=384M ion_c ma_list=“120m,176m,512m” loglevel=8 bootmenutimeout=10 datadev=mmcblk0p2 disp.screen0_output_type=3 disp.screen0_o utput_mode=10 disp.screen1_output_type=3 disp.screen1_output_mode=10
