Hi @daveshah1,

does FFC actual placement let you to use them? I see in the datasheet that actuator opens down so connector should be very close to the board edge. How is it really?

[daveshah1]

I haven't actually got a suitable cable to test with. On the board I have, it seems to move in and out alright at least. But maybe they should be moved to the edge in the next revision.

Hi @daveshah1,

have you already checked clock from U26 oscillator? I'm just a little bit confused with not connected E/D pin...

[daveshah1]

Hi @ki5libs, see #2 - it should be going into a PCLK pair on the left or right side, ideally near the DDR3. As it stands I've been using the 12MHz clock instead.

@daveshah1, yes, I saw that. Maybe I wasn't clear enough, I just want to ask did you check U26 output in general. Is clock OK on both OUT pins without external pull-up resistor. I didn't noticed that datasheet has information about internal pull-up. Sorry, nevermind.
