Raspberry Pi Forums

Hi, I am a newbie. I have just received the RPi.

I have:

-Rpi.
-HDMI cable.
-TV.
-SD Card, 2GB, San Disk, with the Raspbian img (My Ubuntu has done successfully - I hope - the command: dd if= ... ).
-Samsung Galaxy Mini charger (5V output), and I also have tested a BB charger (5V output too).

When I switch on the RPi:

-The PWR LED is red (I think that is correct).
-The OK LED is green (but the light is not very intense...).
But, Raspbian doesn't boot, the TV doesn't detect any HDMI signal.

Thanks and please excuse my english.

If you put the SD card back to your Ubuntu PC you should see two file-systems on the card. One less than 100Mbyte and another taking most of the remainder of the card. And you should see files in both of them.

Now I have put Berryboot but it still doesn't work.

I gonna chech what you have said, thanks.

Can anybody help me?

yeah Im having the same problem

When you put the SD card in the Ubuntu PC, can you see the two filesystems on the card and the files in them?

Nop. But I don't know if I need any special software to see them. I've used Nautilus, a "normal" file explorer, and I cannot see anything.

Put the sd card into a reader and plug it into your Ubuntu machine.

Do

ls /dev/sd*

You should see /dev/sdb, /dev/sdb1, and /dev/sdb2 for the sd card (may not be letter b depending on your machine).

If you do not see these files than your card has not been written properly.

The Ubuntu I use (10.10) automatically puts two new icons on the desktop when I plug in the card reader with correctly written SD card. Clicking on those should show the files.

joan has given some instructions what to do from a command prompt.

I'm having the same problems as others here with a bright red light and tiny pinprick green light. So far I've been unable to really verify the image worked, other than Disk Imager says it burned the image.

I have an older install of Xubuntu. I have a USB SD card reader that I can plug in. When I plug the reader into Xubuntu and follow some online directions, the commands don't pan out and it says error messages.

Can someone tell a non-Xubuntu user step by step how I can go about reading the contents of an SD card? I need to know all the commands to type to mount it or whatever steps Linux requires to make this work.

Thanks!

@bbagnall. You mention Disk Imager. Did you use that on a Windows PC? If yes, that PC and your card reader is enough. When you put the SD card into the USB card reader and plug the reader into the PC, Windows should show another drive letter in 'My Computer'. (It may even automatically open a dialogue box asking what you would like to do with the new drive.) When you open that drive you should see files including start.elf, bootcode.bin, kernel.img, loader.bin and others. If you don't see those files or even the extra drive, then the card was not written properly.

Almost all recent card readers support the SDHC version of SD cards but older readers do not. The ICs in them were made before the SD spec was extended for H(igh)C(apacity) mode.

I only can see sdb and sdb1. By the way, before copying Raspbian to this SD card, Ubuntu automatically detected the SD: like an user has said, in the launcher appeared a red SD icon. But now, that doesn't happen.

I am having the exact same problem. I am guessing I there should be something I see when no SD is inserted? But even with a correct (I hope) installation it does not work.

Thanks, but I finally solved the problem thanks to Berryboot.

No - if the Pi cannot successfully read its boot files from the SD card you will not see any signs of life.

For the benefit of others who may come across this thread in the future, would you care to say how/why Berryboot solved the problem.
