4G-IoT

I need help.
I flashed my 4g-iot and connect for debugging via adb
But I can not see and can not work with the GPIO port.
Also I do not see UART ports, which are indicated in the manual (2 pieces)

I tried java, C ++, Kotlin.
2 day does not work in any way.

We have updated the usage of gpio on user manaul for Orange pi 3G-IOT and Orange pi 4G-IOT

in android 6 it's dosn't work, i try install android 6 from Download and Full calibration, GPIO not work....

/sys/bus/gpio - missing
/sys/class/gpio/ - missing
dmesg | grep -i pio - None

but cat /sys/devices/virtual/misc/mtgpio/pin give me

pin: [mode] [pull_sel][din][dout] [pull en] [dir][ies][smt]
0:11101010
--------
100+:11101010

but i can't config it by
echo -wdout123 1 > pin -This is Set the GPIO to output high level
echo -wdout123 0> pin -This is Set the GPIO to output high level

!! if i use
echo "-w=123:0 0 0 1 0 1 1 0" > pin
Status by "cat pin" changed
but i use electic tester and nothing in 37 changed

WTF??

If the GPIO/serial devices are missing the most likely reason is that the GPIO/serial device driver is not enabled in the kernel, or it was built as a module and then it was not loaded.

I think the official firmware to the device is already with the driver turned on.

@admin please give an answer.
Will linux (not android) be implemented
Will it be implemented android 7+
Will support continue?

Note from the board "out of the box" no support for GPIO port

For linux, so sorry we still working on, sooner would be around middle of next month. For Android, we have made Android 8.1, waiting our engineer to have final test of it. Or if you are available, you could have a test: https://mega.nz/#F!RgcXERLS!Xpx1fhm4I47guXB-zPJRQQ
For any support, i am so sorry i am not good at it, i will try my best as i could.

Not really understand why there is no support for GPIO port？

Now I will try android 8.1
on android 6.0 GPIO ports were not available

Thanks for the answer

I am not sure how is the perfermence of GPIO on android 8.1, so maybe i could wait your feedback.

...

The firmware was successful.
But I can not find the GPIO ports on the device. (like this https://www.youtube.com/watch?v=pV25gWwxSrM)

Copy code

On my Orange Pi Plus2 it works, but I can not even see the folders.

I tried searching

k37mv1_bsp:/sys/class # find . -name "*gpio*"
./misc/mtgpio
k37mv1_bsp:/sys/class #

Copy code

But he did not give results

k37mv1_bsp:/sys/class # cd misc/mtgpio/
k37mv1_bsp:/sys/class/misc/mtgpio # ls
dev pin power subsystem uevent
k37mv1_bsp:/sys/class/misc/mtgpio #

Copy code

It is not something with which to work.

Maybe I'm doing something wrong?
I tried to find all this through the adb shell.

I'll write here, if I find something and wait for your answers

lsmod
