打开r40平台tinav2.1下接U盘

2017/11/14 16:51

版本：V1.0

开发板使用：CB-S（需要给USB1供电）

0、需要打开USB1的电源使能（PI09）！

W:\ov5640_spi20_r40t\target\allwinner\azalea-m2ultra\configs\sys_config.fex

;--------------------------------

;--- USB1 CONFIG

;--------------------------------

[usbc1]

usbc1_used = 1

usb_drv_vbus_gpio = port:PI09<0><1><default><default>

;usb_drv_vbus_gpio = port:PI1<0><1><default><default>

usb_host_init_state = 1

usb_regulator_io = "nocare"

usb_wakeup_suspend = 0

1、原始编译r40平台的tinav2.1系统：

rootroot@cm-System-Product-Name:/home/wwt/r40$ tar zxvf r40_tinav2.1_leo_20170112.tar.gz

rootroot@cm-System-Product-Name:/home/wwt/r40$ mv tina/ r40_tinav2.1

rootroot@cm-System-Product-Name:/home/wwt/r40$ cd r40_tinav2.1/

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ source build/envsetup.sh

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ lunch

13. azalea_m2ultra-tina

Which would you like?13

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ make -j12

rootroot@cm-System-Product-Name:/home/wwt/r40/r40_tinav2.1$ pack

2、刷机之后，插入USB鼠标，红灯亮！DEBUG口的打印：
