MaxK1

I don't think anyone ever said 700mA was enough for the Pi, a keyboard AND wifi... As for power supplies "degrading" - a poorly designed supply/charger can degrade VERY suddenly

MaxK1

I'd take a good hard look at the SD socket and it's connections. Perhaps it is in a case that is causing some kind of mechanical pressure on the SD card or connector? Bad solder joint on the connector or a slight crack?

What LEDS are lit on the board? Does the SD card and surrounding area feel warm(ish)? For that matter, does anything on the board feel hot or warmer than you expected? Are you Overclocking? And have you performed an apt-get update and apt-get upgrade? Anything in the logs?

Screensaver - the Rpi is still running

MaxK1

Raspbmc does something similar, but at least it allows you to keep up to date and to overclock. I use separate class 10 cards for raspbmc and class 4 for everything else since they are only used to boot the system and run from an external HDD. I assume that using berryboot breaks rpi-update. I would...

500mA supply may not be enough.

MaxK1

Did you get 4.77V with the other supply as well? That's getting close to the low end of reliable operation, but it should not be just crashing like that. I assume that's through the Micro USB power connector? I have encountered problems with those in the past, any chance you can power it through the...

MaxK1

I came across something, somewhere in here that at least hinted at a bug/problem/feature where berryboot had a problem with config.txt. Can't find it now (Of course!)

MaxK1

Check your /var/log/ directory as well. Often you'll find a little extra room can be freed up there as well.

MaxK1

Can you measure the voltage at TP1/TP2? I suspect when it fails, it has dropped well below 5V. Also try without the mouse and ethernet. Do you get any further?

MaxK1

XBMC has a display calibration option - can you fix the display by using that? If so, that would suggest that the config.txt file is being ignored by Berryboot somehow (I don't use it so I don't know) If XBMC screen calibration works, that should tell you that your screen, cable and Rpi work. If you...

MaxK1

Could you provide more details on keyboards/mice/display, network/wireless, Powered/unpowered USB hub and power supply? Model A or B?

MaxK1

Probably the best option.

MaxK1

That's the kicker - GENUINE. I have a couple of Sandisk cards where the plastic seems awfully brittle and prone to flaking off and/or cracking - much more so than other cards I've used. (I no longer use them) I suspect the cards are not genuine...

MaxK1

It's in /boot/config.txt You may not need all of them - I'd try config_hdmi_boost=4 Also (And this may sound weird) try reversing your HDMI cable! I have one (And others have reported this as well) that only works one way. It also needs to be pushed in _very_ firmly - a fraction of a mm may make con...

MaxK1

The card is 4G but the partition isn't. Expand that first to make the entire card available.

Control Panel? Add/Remove Programs? Sounds like a Windows(tm) concept...

MaxK1

Run raspi-config - select 2nd entry "expand_rootfs" Sit back and wait for it to complete....

Reboot and try upgrading/updating again.

MaxK1

Can you post the output of lsusb? Does dmesg show anything with the non-working HDD?

MaxK1

Expand your file system! You are 100% full.

MaxK1

And your screen is a?

I had the sleeping xtal problem on my 3rd Rpi - a rev 2 model B. A sharp rap with my finger nail on X1 solved that. Been running >3 months just fine.

MaxK1

I've started looking into this a little more - the only observation I've made and conclusion is the Ralink is not as sensitive as my Realtek 8087 and is more prone to disconnect than the Realtek. I have some suspicions about the Ralink as it almost always comes up with the rate 1 Mb/s whereas the th...

MaxK1

when I had power problems I used an old pc psu for the 5 volt rail these can offer way more ampage and may be your best option That's the way to go - power the pi through the GPIO header, feed 1 or 2 USB hubs as well. My next Pi will probably be running 1 or more 3.5" HDD's so I was thinking of car...

MaxK1

If it has 2 USB ports + Ethernet - it's a model B. If it has 512M, it's a Rev 2. If USB+ethernet don't start (from power up) it may be the dreaded "sleeping crystal" (X1) but I haven't experienced or heard of X1 going to sleep and waking up again. My model B/Rev 2 had that initial problem and giving...
