I've been playing around with playing MP3's on the Pi. What I noticed is that the sound with OmxPlayer is louder (better quality maybe too?) than mpg321. I believe they are using a different library each for playing the MP3's, been searching around but just not able to find any topics on this. Does ...

Thanks guys! I'm going to look into this and consult the hardware guy (and reference to this thread) We did see issues that the GPIO output was sending high/low for no reason, but when we connected the monitor to the sending Pi, the issue was gone. So it was grounded via the monitor. The second Pi i...

so that could damage the hardware, if it is not grounded? We are experiencing hardware issues and still trying to find the cause.

Sorry for the late reply! I thought I would get a notification when someone responded.

No, the second Pi is not grounded, could that be the issue?

I have one Pi which needs to respond to another Pi's change of a certain pin. So let's say I have pin 7 from one connected to pin 7 of the other. This is al working; toggling the pin allows the other one to see it change. But after a while, it looks like the second Pi (getting the input) is being de...

Thanks guys for your replies! I checked the image file with kpartx, but still only one partition. I think the image really failed. I'm going to use my Ubuntu laptop now to make a copy and a 32gb SD card instead of a 16gb. Let's hope that helps. The sd card is used in a working environment, so I cann...

Hi I've tried multiple times to clone my Pi's SD card. I did dd if=/dev/rdisk2 of=pi.img bs=1m using OSX. I get an image. But after writing it to another 16gb card, it gives a kernel panic: VFS: Unable to mount root fs on unknown-block(179,2) I read about slightly smaller SD cards giving this kind o...
