New Pi not booting

Got a new Pi for Christmas.

Power supply is an Apple micro usb charger, so it could be my power supply.

Loaded the wheezy image to the SD card from my laptop. I am running Maverick (Ubuntu/Debian) on my laptop, and used dd to load the SD card. Funny thing is that once I put the image onto the SD card, I can no longer read it on my laptop. Only way to get the SD card to be visible again is to re-format the thing on a camcorder. Wondering if the blocksize on the dd command (using bs=4M) is important here? This is what I use to burn the SD card:

sudo dd bs-4M if=/media/disk01/RPi/2012-12-16-wheezy-raspbian.img of=/dev/mmcblk0p1

I have tried burning the image a few times, on two different SD cards (both on the approved list on http://elinux.org/RPi_VerifiedPeripherals#SD_cards), but all I get is one red LED lighting whenever I apply power.

So is it really my power supply? How long should it take to boot up (or show any signs of life) when you apply power for the first time? What type of activity should I see from the LEDs? I only have the video out connected, no usb devices (keyboards, mice, etc), no ethernet, no audio.

Hi,

exactly the same problem when I try to use the raspberry the first time. I see in the folowing link http://www.youtube.com/watch?v=QlEZI9YABVQ that 4 leds has to be on .... but I get only the red one like you even if I dont plug any other thing.

Alim : 5V/700mA
Model : raspberry B

So I see two possibilities :
* the 700 mA are not sufficient
* the card of the rapsberry is dead ... at the origin

Anyone to help us ?

Ok you have found the wiki there are some Noob pages take the following as start points

http://elinux.org/RPi_Noob_Guide_to_the_Pi_image

Noob is not derogatory the noob is just the lower end of the noob--geek spectrum being a noob is just your first step towards being an uber-geek ;)

If you find a solution please post it in the wiki the forum dies too quick

sudo dd bs-4M if=/media/disk01/RPi/2012-12-16-wheezy-raspbian.img of=/dev/mmcblk0p1


I think this should be:
sudo dd bs-4M if=/media/disk01/RPi/2012-12-16-wheezy-raspbian.img of=/dev/mmcblk0
You should copy to the sd card, not to the partition on it.
After a removal and reinsertion of the sd card, you should see it's partitions. (One fat32 and one ext4)

Hi,

thanks for your answer ... your command to create the system disk is the good one ;) .

The raspery start correctly now.

Happy Christmas !

Getting rid of the partition from the target worked. Pi comes up great now.

Used this command:

dd bs=4M if=/media/disk01/RPi/2012-12-16-wheezy-raspbian.img of=/dev/mmcblk0

(even though mount point was /dev/mmcblk0p1, got rid of the "p1", and then once I was done copying the image, I could see everything on the SD card on my Linux laptop.)

Thanks @obcd! Any way to give reputation points on this forum? I owe you a few of them....
