rk3288 linux buildroot camera调试

首先要使能，用gpio控制

cat /sys/kernel/debug/gpio
GPIOs 0-23, platform/pinctrl, gpio0:
  gpio-5   (                    |GPIO Key Power      ) in  hi   
  gpio-6   (                    |vcc_phy             ) out hi   
  gpio-12  (                    |vcc_otg_vbus        ) out lo   
  gpio-14  (                    |vcc_host            ) out hi   
  gpio-17  (                    |vcc18_dvp           ) out hi   

GPIOs 24-55, platform/pinctrl, gpio1:

GPIOs 56-87, platform/pinctrl, gpio2:

GPIOs 88-119, platform/pinctrl, gpio3:

GPIOs 120-151, platform/pinctrl, gpio4:
  gpio-127 (                    |mdio-reset          ) out hi   
  gpio-139 (                    |bt_default_rts      ) in  hi   
  gpio-146 (                    |bt_default_wake     ) in  hi   
  gpio-148 (                    |reset               ) out hi   
  gpio-149 (                    |bt_default_reset    ) out lo   
  gpio-151 (                    |bt_default_wake_host) in  hi   

GPIOs 152-183, platform/pinctrl, gpio5:

GPIOs 184-215, platform/pinctrl, gpio6:

GPIOs 216-247, platform/pinctrl, gpio7:
  gpio-218 (                    |enable              ) out hi   
  gpio-219 (                    |enable              ) out hi   
  gpio-224 (                    |vcc_3g              ) out lo   

GPIOs 248-263, platform/pinctrl, gpio8:

可以看到gpio8是从248开始，GPIO8_A6 就是248+6=254

echo 254 > export

cd gpio254/

echo out > direction

echo 1 > value

然后用lsusb就可以看到设备了。
