Re: Trouble with video over 3.5mm jack with B+

Just in case: black & white fuzzy image sounds like you are feeding the composite video signal into a s-video input.

Re: Model B+ Audio Experiences

It is relatively easy to perform frequency response, noise and distortion measurements using RMAA and a decent sound card.

Reboot seems to shutdown all processes and flush caches, etc. I'd say it calls shutdown but I would have to check it, thanks.

Re: Sporadic SD rootfs corruption on reboots (no overclockin

Hi Henry, Can you share your script for rebooting the pi every 90 seconds--is there a way to get it running on Win7? Sure, I'm uploading the files I use. I wrote a small c program for the loop, it calls the 'cmds.bat' file, which calls the ssh client Putty with the appropiate parameters. You'll als...

Re: Pi keeps corrupting filesystems

I've subjected my Pi to rebooting tests, and at the end the rootfs on the SD always gets corrupted: http://www.raspberrypi.org/phpBB3/viewt ... 28&t=21385

Sporadic SD rootfs corruption on reboots (no overclocking)

Hi, I have a rev.1 Raspberry Pi board I got on June. Since having it, I've been suffering from occasional corruption on the SD when booting/rebooting. At first I thought it was due to early software issues. But with latest updated Raspbian (as of 2012.10.12) I was still having corruption sometimes, ...

Ok, that was the problem. I did 'sudo apt-get install gparted' and now it works under X simply doing 'sudo gparted'. Sorry for the 'noobness' and thanks.

Hi, I'm quite new to Linux. I'm trying to launch graphical GParted under X in Raspbian. As opposed to Squeeze, there's no shortcut in the menu to GParted. After some search, I found I have to use "gksu gparted" in a terminal, but it gives me an error "GLib CRITICAL **: g_str_has_prefix: assertion 's...

Re: USB Port Current Boost

What about feeding the USB device directly from the charger but isolating its power pins from the PI ones? I mean, using a modded cable in order to feed the USB device.

Re: My Pi needs some resting after power off

In my case measured voltage between TP1 and TP2 is 4.89 volts. Strangely, the SD card that works OK gives some timeout errors, the SD that causes the issues gives no timeout errors.

I can barely stand the heat on the controller chip on my PI, with just the keyboard attached. My finger nearly hurts. It's around 24ºC ambient here.

Confirmed, it happens only with one of my SD cards, its an old 2 GB SanDisk class 2 card. I guess I'll have to put it to rest and buy a new one.

Well, it's not happening now. I'm using a different SD card (the same I used the first day) and it's working fine now. I have to try with the other SD card.

No, just hdmi/composite keyboard and ethernet. I think it also happens without ethernet. I think the first day it didn't happen, it started the 2nd day.

Most of the times, after shutting the operating system and removing the power plug, if I plug the power again the Pi won't boot, the red led lights but the green one not.
