Sorry my internet was bad. Now i have better internet. Unforutunatly i dont have multieter. i will look for it. How can i understand OPİ is still intact by multimeter. İ hope my cable was not enuough for 2A

Good that your inet is back

I would use the multimeter first to check the polarity of the plug. Then if the polarity is right I would see if the OPI starts with any LEDs lighting up. If that works you can check the voltage at the 5V rail (GPIO pins 2 or 4 for 5V and pin 6 for ground) with the volt/multimeter.

Please let us know what happened

Thank you. I'll do it tomorrow

Where can i find which gpio pin do what?

is it same with that?

is it same with that?

OPI has 4 GPIO numbers.
(1) The number when using WiringOp Library(physical pin number).
(2) The number when using WiringOp Library(WiringPi pin number).
(3) The number when using WiringOp Library(GPIO pin number).
(4) The number when operating using a device file.

(1)(2)(3) is same as RPI.
(4) is different from RPI.

Pin#18 ON/OFF using device file.

RPI
$ sudo sh -c "echo 24 > /sys/class/gpio/export"
$ sudo sh -c "echo out > /sys/class/gpio/gpio24/direction"
$ sudo sh -c "echo 1 > /sys/class/gpio/gpio24/value"
$ sudo sh -c "echo 0 > /sys/class/gpio/gpio24/value"
$ sudo sh -c "echo 24 > /sys/class/gpio/unexport"

OPI
$ sudo sh -c "echo 71 >/sys/class/gpio/export"
$ sudo sh -c "echo out >/sys/class/gpio/gpio71/direction"
$ sudo sh -c "echo 1 > /sys/class/gpio/gpio71/value"
$ sudo sh -c "echo 0 > /sys/class/gpio/gpio71/value"
$ sudo sh -c "echo 71 > /sys/class/gpio/unexport"

Hi,
Have you checked the polarity of your cable and have you improved it?
Once you have done that, check the voltage in between GPIO pins 2 or 4 (5V) and pin 6 (ground). The voltage must be above 5.00V.

The pinout you find if you just type "GPIO pinout" in the search bar or here: http://www.orangepi.org/orangepi ... light=gpio%2Bpinout

Yeah it worked. But screen doesn't come. İnternal memory doesn't have android i think. İt doesn't boot. Just red light is on. How can i access to internal memory. Opi pc plus has 8gb internal memory.

How can I upload os to the EMMC?. And how can I access to the EMMC by the micro usb? I pluged it to computer but nothing happened

Yes, leds do turn on, but later in the boot process. Leds on network connector are first IIRC:

Hi which led do what. When I plug the 5V red led is on. Then yellow for 2 seconds. Then again red led is on. And nothing happens. Then on press button. Yellow led is on.
What happens to led while booting
Sorry for bad language
Thanks
