sysconfig.fex文件中已经配置
[usbc0]
usb_used = 1
usb_port_type = 0
usb_detect_type = 0
usb_id_gpio =
usb_det_vbus_gpio =
usb_drv_vbus_gpio = port:PB09<1><0><default><0>
usb_restrict_gpio =
usb_host_init_state = 0
usb_restric_flag = 0
usb_restric_voltage = 3550000
usb_restric_capacity= 5
现在别说adb shell不能用,我一插usb,板子就死机了!好几个人都遇到这种情况了!
我的A10如上配置确可以用!A20就不行!
