全志 H6 Orange Pi Lite 2 Android 7.0 OTG配置
阿新 • • 發佈：2018-12-10
問題原因
因為之前沒有電源線，一直使用OTG口進行供電，找到了條PSP的電源線，發現可以使用，也算是閒置物品再利用吧。測試時發現OTG功能用不了，接下來繼續解決。
檢視原理圖，確認管腳
檢視原理圖可以確認，OTG部分使用的是USB0模組，並且有IDDET，檢測埠，這個埠是用來區分OTG所扮演的角色，是HOST還是Device。電平觸發。IDDET管腳連線到晶片的PC6口。
sys_config.fex配置
找到OTG配置項
;--------------------------------
;[usbc0]: usbc0 configuration.
;usb_used: usb controller enable. 0-disable, 1-enable. 下面解析下每項含義 usbc0_used = 是否使能 usb_port_type = USB埠型別，0-device only，1-host only，2-otg usb_detect_type = usb hotplug detect mode. 0-none, 1-vbus/id detect, 2-id/dpdm detect. usb_detect_mode = usb otg switch has two config. 0-thread scan, 1-id gpio interrupt. usb_id_gpio = usb id pin配置 usb_det_vbus_gpio = usb det vbus pin配置 usb_drv_vbus_gpio = usb drv vbus pin配置 usb_host_init_state = host only模式下，host埠初始化狀態，0-初始化後usb不工作，1-初始化後usb工作 usb_regulator_io = usb供電的regulator gpio usb_wakeup_suspend = 是否支援usb喚醒功能 usb_luns = 使用mass storage功能時碟符數量 usb_serial_unique = usb device的序列號是否唯一：1唯一，使用chip id；0相同，使用usb_serial_number制定 usb_serial_number = usb device的序列號 rndis_wceis = wireless rndis使能標誌，1使能；0禁止。
從程式碼中看到，USB0預設被配置成為host模式，目前沒有OTG接頭，無法測試Host模式，接下來我們需要按照原理圖配置成OTG模式

這裡我們可以看到，用USB線連線電腦，會出現相應的裝置。連線Total Control，可以方便沒有螢幕的情況下進行除錯。因為板載的是無線網絡卡，往往跟我們電腦不是同一個IP段，不能使用WIFI ADB，這裡我們配置成OTG口，就可以使用USB ADB，方便除錯，不需要每次都連線串列埠。
