Hoping to get some insight from anyone who is successfully using the I2C expansion board.

I'm using the Pine temp/humidity sensor...tested with some python code (grabbed from the web and modified) and the sensor works great when using the Pi Bus I2C pins. It also works with the I2C expansion board plugged in and connected to the expansion board pins.

When I plug into one (any) of the I2C expansion board ports, nada...I get an I/O error. After some quick troubleshooting, I see that the device is no longer seen on the I2C bus when i do an i2cdetect command. The fact that the bus pins are confirmed functional, and its specifically with the board ports, it suggests to me there is something more needed that I'm missing.

I have a second I2C expansion board, same issue, so would not appear the board is defective.

Jumpers are on the 3.3v pins as I've confirmed they should be.

I'm running debian-mate, and since I2C works from the bus pins, I don't see it as an OS issue. KH Goh mentioned checking bus speed and confirming its at 10 khz, but would think bus speed would not be a factor as far as being able to see the device on the bus. That said, if anyone can tell me where within the OS configs I can check I2C bus speed, I'd love to eliminate that possibility and also know where it is for future reference.

There is not a lot of detail on the wiki page regarding the expansion board, but I interpret what is there to suggest that I should be able treat the expansion ports just like I would a connection direct to the bus pins.

Thoughts?

Hi
It has been 1.5months since i received my tracking no. for PINE64. My tracking no is RI902593558CN. Can you please help to verify? Not sure if the package is found or something?

Can't update to Android Release 20160711. I launch the Update app and it says "Undiscover new version". I haven't rooted Android. What should I do? Can I perform an online or local update without lose my app configuration?

Just got my board and was wondering if I can use and exsisting power button and reset button that is already on the enclosure I want to use. There are little holes to put wire through and solder up. Just don't want to mess anything up. I can't find anything to helpful yet. It seems a little to new yet. Under the word Power there is 2 big holes and 2 little holes with a plus in the middle. It is the same under the word Reset as well. There is 2 wires on each button on the enclosure I am using. So it looks like it will work out. Like I said I just want to make sure. Thank you for any help I can get. This is my first post. So I hope I did it right.

Hi,
I see that my hard drive won't even turn on from the pine's USB port.
I know Raspberry PI has a max current setting that can be set on config.txt (max_usb_current=1)

Is there any equivalent setting on the Pine64?
I know I can use a powered USB hub (or cable), but that's very cumbersome comparing to a config change.

Thanks!

Hi all,
Just got my pine and was eager to test it out.
I installed Linux (latest debian) and was able to do most of what I needed - sshd, nginx, clang, all kinds of goodies!
However, when I start Kodi it is unusably-slow. It takes like 10-15 seconds to update the cursor position.
Is this related to the long fore-coming Mali driver? What exactly goes wrong?
Thanks!

Hello

I just purchased the Pine64. I am looking forward with playing with it.

Has anyone successfully loaded ROS (ros.org) onto the Pine64 and if they did, what operation system did they use? I went to the ROS website, unfortunately there is not much there on the subject unlike RPI3.

I have not yet tried any of the OSs but I am thinking Ubuntu will be the first .

Thanks Jesse 

So, I've tried every trick the others could throw at me to get the analog audio to work, but nothing. I can get the analog audio to show in the system preferences and PulseAudio Volume Control AND the meters move that something is attempting to output, but... nada.

So I thought, A-HA, I'll use Bluetooth...except that when I select the Bluetooth Manager (using Ubuntu MATE)... an error dialog "Connection to BlueZ failed. BlueZ daemon is not running, bluesman-manager cannot continue. This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started."

I am using the Pine64 WiFi/BT POT. WiFi IS working, but apparently BT is NOT.

When I run through an HDMI cable through a TV, I get sound, both for Android and Ubuntu. But no sound any other way.

Help?

I got 2gb board with Remix (64gb SD) installed and have never been able to get internet (Ethernet)to work. I have tried with every version since day 1. under Ethernet settings it shows my current ip and dns and everything.

Any clues?

Also when i power down or reboot it doesn't recognize my mouse. I have to unplug it and replug it to see it.

I tried searching before posting but search word must be at least 4 letters and "fan" is it 3. So please excuse me if this has been asked before. Thank you.

My question regarding the fan is, is there a way to have the fan come on only when the OS (Remix in my case) is running? For example, my fan will stay running as long as the pine is plugged into the wall, even with the OS shutdown. I do not want that.
