I have a similar problem, although in my case, it's on a dhcp connection. I do have this working properly on a static IP pi, simply by setting interfaces as listed above. The one I'm having problems with is configured in interfaces as follows: auto lo iface lo inet loopback auto eth0 allow-hotplug e...

lol, my life as a geek is filled with examples of things that I've done successfully, that were preceded by other's statements of can't and shouldn't... :D This is an upgrade of an older device that we've been using for the past 8 years (that I was commissioned to create as an upgrade of the DVD pla...

The hardware guy set up GPIO2 as input, he was working with firmware prior to July 15, 2014. Based on his design, the model B rev2, and the firmware at the time of his design, it (signalling on GPIO2) worked. So while I don't know why it DID work, on boot GPIO2 was high (I do not know how pin3 begin...

OK, I went over to the raspberrypi/firmware github, posted an issue and worked with popcornmix to get a resolution on this: https://github.com/raspberrypi/firmware/issues/321 It was discovered that a post July 5th, 2014 gpioman firmware update created this new behaviour of GPIO2 which subsequently c...

*sigh* Oh, no they didn't... OK, I checked firmware versions. The device that the hardware guys uses is: Jan 6 2014 21:19:57 Copyright (c) 2012 Broadcom version b00bb3ae73bd2799df0e938b7a5f17f45303fb53 (clean) (release) The systems that are "broken": Oct 1 2014 22:40:40 Copyright (c) 2012 Broadcom v...

Hi Joan, thanks very much for the response. BTW: I plan on making extensive use of your pigpio. :) Unfortunately, I cannot comment too much on the external hardware attached to pin3 (proprietary and I don't entirely understand it, myself) I'm just the software guy on this project, but the hardware D...

I'm guessing the question of what board and what firmware will be asked, so:

Pi Model B rev.2
Current firmware (using rpi-update)

I'm getting some, what I would call strange, although this may be expected by those with better understanding than I have, behaviour from GPIO2. Using Raspbian, on generic configuration, GPIO2 is set as "in": echo "2" > /sys/class/gpio/export echo "in" > /sys/class/gpio/gpio2/direction A hardware de...
