Connect i2c under Remix OS - IlyaM - 05-07-2016
Hi everyone. Could you tell me how can I connect i2c device to pine64 under Remix OS. I plugged pins to pi-2 connector of pine64
Vin -> Pin1 (Vdd)
GND -> Pin6 (Gnd)
SDA -> Pin3 (SDA)
SCL -> Pin5 (SCL)
Wrote some app on Android to detect I2C device, it shows no devices, moreover my i2c device has led which is on when the vdd is plugged, i see that led is off.
I've attached the picture where you can see how my device plugged and its state (led is off)

As expected, Allwinner forgot to enable the necessary kernel config bits. I2C in Android/RemixOS can't work.

Hmmm....
Thanks for your reply!
Is there any way how to include I2C in kernel? Maybe rebuild it? You share the link where can I find this config file. Thanks in advance
p.s.: I was wrong, the power pin from pi-2 is working, my device (BMP180) doesn't have a led (forgot about it), so I attached it to +5v of pi-2 and GND of pi-2 and screened logs from arduino (where I use 2 pins of i2c)
