Re: Not booting up, stuck on Power LED, no OK LED.

Tue Apr 17, 2012 7:45 pm

Hi,

Got my R Pi today, and downloaded the Debian Squeeze.

I have three cards: a Sandisk Extreme3 SDHC 4GB Class 6, a Panasonic Silver Class 4 24GB, and a Kodak 4GB class 2.

I followed the instructions to dd the image onto my cards (checked the SHA-1 first which was correct), first up, the Sandisk 4GB. I plugged everything in and connected the power and it just hangs on the power LED, not making any suggestion that it's going to the OK LED and booting up. So, I decided to try the Panasonic 24GB, the exact same problem happened. For both, i've tried re-inserting the SD card and putting the image back on, but to no avail. Then the Kodak one, and same problem again. So I tried downloading the Fedora distro, and same again, nothing.

Will this really be a problem with the SD cards or something else?

Thanks

Tim.

Something else would be my guess - would expect at least one of those cards to work.. Take a look at some of the other topics in this section - weak power supplies seems to be a problem in some cases.

Do you get any HDMI output at all? Try unplugging everything from the USB/ethernet and powering up. The red light should go on, then the green one next to it should flicker after a couple of seconds. Are you getting any green at all?

I'm having the exact same problem with mine. Only tried it with a single SD card for now, but I've tried 2 power adapters and neither work. Both adapters are 5V 1A and are good quality, so no idea what the issue could be.

Hi James, thanks for replying.

Okay, i've tried a few things now. Realised that my power supply wasn't powerful enough - for some reason I thought it needed to be at least 0.5A, but actually just saw it was 0.7. I've tried it with a 0.7A supply (it's a Samsung mobile phone charger), and still nothing happens. Then a 1A supply (iPhone charger) and still nothing happens.

It says No signal when connected.

I disconnected everything except HDMI (and SD), then connected the power and still nothing, i'm not sure the colour of the light (i'm colour blind, can't tell the difference between the small red and green lights), but it doesn't flicker, just the Power light stays constant. I'm a bit baffled.

Tim.

Same story here I'm afraid - red power LED is on but nothing else and nothing on the HDMI screen. I have a 700mA power supply and have tried a class 2 Sandisk and a class 4 Kingston.

We'll get there!

Same here as well, tried 2 different cards & 4 power supplies.

Duff board?

Where did you guys get yours from? Mine from RS Components.

RS, yes, but hopefully there's something simple we're missing...

Same here.  RS board, 2 different power supplies.  Red PWR LED on no other signs of activity, no output to HDMI or analogue video to various displays.  I have my fingers crossed there is something simple I am missing.

card formatted before installing the disk image? Not sure if that should be necessary, but check out these threads:

Yes, I formatted, is there a specific format it should have been done to?

Hang on a second.... I think i've made a big big mistake. dd'd it to disk2s1... instead of disk2. Trying it again now.

Sigh, it's been a long day.

All working now .

For those with the same problem, I fixed it by taking off the "s1" when you type in the dd command.

So it looks like this:

dd bs=1m if=~/Downloads/debian6-13-04-2012/debian6-13-04-2012.img  of=/dev/disk2

instead of this

dd bs=1m if=~/Downloads/debian6-13-04-2012/debian6-13-04-2012.img  of=/dev/disk2s1

Fixed - 'if you can't do it on the command line you are doing it wrong'  I was obviously doing it wrong!  Bad disk image was my problem,  did not think of this first as thought there would be some kind of video output anyway just to say it could not read the loader.  Now I have the keyboard repeating issue but progress is progress.

Yup had exatcly the same symptoms, and it turned out I also made the same mistake with dd ; the "of=" parameter must point to the raw disk device and not a paritition on the device.

All up and running now

I had the repeating/missing key press issue last night when using a Kindle charger at 0.85A. When I switched to plugging the device in to a USB port on my PC the problem went away. So I think that is a power issue.

I just make a slight update to the Wiki article on setting up the SD card

http://elinux.org/RPi_Easy_SD_.....d_in_Linux

which hopefully makes the use of sdd not sddp1 (or similar) a bit more clear, although it was mentioned already.

If you want a laugh, my schoolboy error was dd-ing the zip file instead of the .img. All fine now...

Still not working for me yet, but I'm using windows to try and image the memory card using win32diskimager as recommended on the downloads page.

 Win32DiskImager.

Tried it with a micro SD card in an adapter and a brand new SD card with the same results now. Going to get hold of a linux machine tomorrow and try creating the card that way.

I've now tried imaging the SD card with a linux machine and the same results. No idea which way to go now, I can't get my Pi up and running

After you've imaged the sdcard can you see files in windows?

You should see the small FAT partition, containing start.elf, kernel.img etc.

Yep, can see all the files in Windows and the different partitions.

Just gone out and purchased a SD card that is on the known working list and still the same issue is there. I'm going to try a different distro now and if that doesn't work, it looks like it will be going back to the supplier as faulty.
