Re: Reboot problem

It's a SanDisk 4 GB SDHC, class 4, with BH1029316016G printed in the back. Beats me what actually breaks it like that! It seems like my SD card works now after running apt-get update && apt-get upgrade on Debian wheezy. Before, a reboot left it in a limbo state where it refused to boot up before a ...

Re: Reboot problem

I tried Arch Linux on the same card; it would not even boot. It's a SanDisk 4 GB SDHC, class 4, with BH1029316016G printed in the back. Beats me what actually breaks it like that! I flashed Debian back and used it to install the much smaller OpenELEC distribution on another, smaller card (mounted it...

Re: Reboot problem

Right now I am using whatever rpi-update gives me from github. I started with the original Debian image (debian6-19-04-2012, I think) and it's been like this since the beginning. I will try with other distros also, just in case there's a difference. Sometimes a dirty reboot by removing power and imm...

Re: Reboot problem

My Raspberry Pi also has problems booting up. I have tested two different power supplies (both capable of several amps) and tried connecting nothing but (composite) video, or nothing but the network cable for connecting with SSH. I power the Pi through an active USB hub. Voltage output at the ports ...

Re: GPU Version

I ran rpi-update and got that same error but:

Code: Select all

/opt/vc/bin/vcgencmd version

So I guess it's fine? Or should I run it again just in case?

Re: 2 different Pis behave differently

Yep, I have a Farnell Pi (early) and RS Pi (later build) and they are different. Older one won't re-boot immediately after a power down, sometimes it takes minutes before it will come back to life. Mine is from Farnell, one with CE and FCC stickers if that helps at all with determining its age (do ...

Re: voltage and polyfuse

I have now tested it with another, surely better quality general purpose power supply (capable of 5.2 A at 5 V) and it's the same deal. After a clean shutdown it does not boot up again, and the test point voltage rises up to the supply voltage. It's like the SoC simply does not wake up again, not un...

Re: Pi won't boot

Do you have a multimeter so you could measure the voltages the Pi receives? If you look at the board closely, you can see two points marked TP1 (almost between hdmi and power connector) and TP2 (at the edge of the board next to the yellow connector). Putting test leads into those holes would tell yo...

Re: USB Hub powers RPi accidentally

I'm wondering about this as well; turns out my Pi doesn't quite fully boot up and run with the "back-fed power". It partially boots and then seems to get caught in a loop where it reboots endlessly, like it doesn't quite get enough power. I'm considering making special USB cables for Pi use where th...

Re: voltage and polyfuse

I am powering my Raspberry Pi through a powered hub that is powered by a 2.5 A wall wart. I don't know its quality exactly since I don't have an oscilloscope, but I could find out I guess. Voltage output at the ports of the powered hub is 5.1 V. Measuring TP1 and TP2 of a running Raspberry Pi gives ...

Re: GPU Version

What worked for me was: /opt/vc/bin/vcgencmd version ...or it might have been the command alone without the "version" attribute. In any case the command in the wiki does not exist. Also, with the latest versions of everything for the boot partition from git, this command now returns an error about a...

Re: Debian picky about config.txt?

I seem to have a very similar problem. sudo shutdown "now" -r shuts down the system, but it does not reboot. As a matter of fact, my Raspberry Pi seems often reluctant to boot up at all once this happens. shutdown with the -f option is no different it seems. Currently I do not have a config.txt and ...

Re: Who was the fastest in the morning?

I'm amazed anybody got one. Raspberrypi.org responded immediately at the top of the hour and I then followed the distributor links right away -- within the first minute -- only to find dead websites, and that's the whole story.
