Ongoing Raspberry Pi problems

Just return the bloody thing. Its obviously broken; other people pointed out the other leds should light up as well. Next time try it with the card that comes with it (or order a complete kit with pre-formatted SD card).

Knowing Lancaster, I'd guess he found it at a salvage yard ;-) ...Jim Thompson

I got one with the OS on the SD card already. Plugged it into the HDMI port and it booted up the first time, no problems. Typed "startx" and I was in business, Internet connectivity and all.

How did you prepare your SD card? Did you use the Windows Imager utility?

I downloaded wheezy.zip in windows 8 in on and then drug and dropped it into the memory card.

The card showed nearly the full 2 gigs from the much shorter zip file and an .img trailer.

Doing this twice seemed to produce the same restult.

From the looks of it you need to get this utility to setup the boot sector on the sd card.

use the wheezy img file as the source. This creates the boot partition on the sd card. I'm assuming it?s a linux disk with multiple partitions, but I could be wrong.

Cheers

that's not going to work

you need to overwrite the memory card with the img file dunno how to do that on ms-windows

The SD Card is Linux format. You have to use a special imaging tool to make one on a Windows PC.

That's your problem, you didn't RTFM.

Watch this:

Is it a clean 5.01 volts?

You'll need an open DOS window for this approach.

You can use "dd" from here:

dd copies the raw data from the img file to the device.

dd --list will show you the device IDs ; one will be for the memory card when it's plugged in.

The mount point for i: on this machine is

\\.\Volume{68c3864c-134e-11e0-ab8e-806e6f6e6963}\ link to \\?\Device\HarddiskVolume7 removeable media Mounted on \\.\i:

so you can refer to the device at I: as \\.\i:

Oh come on, now I know you are trolling or getting senile.

My TV Typewriter doesn't work. It was too much trouble to read the instructions so I just drugged and dropped all the parts into the box. Should I have taken them out of the plastic bag first?

I found this particular problem. I was copying an .img file into the SD card rather than imaging an .img file into it. The needed image copy software is extremely dangerous.

The pi now boots but has monitor problems.

The instructions on the Wiki (particularly) are concise, accurate and worked for me on the first try (re: imaging my own SD card).

It's like a sharp knife - also extremely dangerous when inexpertly used.

Check the forums:

HTH Chris.

Mine did at first too. You have to manually go in and set the screen resolution. I turned off "overscan" in config.txt and it worked fine.

It explains how to load the SD card from Linux or Windows so that it is bootable. It also

warns that using Word or Wordpad is likely to corrupt the load. The references at the

bottom of the page explain how this flavor of Linux is attached to the hardware. I have not

done it yet, but I will do it soon. I have some HDMI monitor issues to work out first.

A good early checkpoint is to lug the composite video to a TV set with a composite video input. make sure that the SD card is seated properly and plug the power in. Nothing happens for a few seconds and then the screen will start scrolling and it may do a restart. eventually, it will get to the login in point. Since there is no keyboard-mouse installed you cannot go further. Note that the video is nearly unreadable, but it does show that it will boot.

There is so much >>>

Heh! I wouldn't post bad information in this group, you guys are likely light years ahead of me in electronics design. I just post my own experience, no guessing. I would look like a fool against some of you if I went around guessing. ;-)

Theres's a section covering two linux GUI linux tools and a link to a command-line method

As the others have pointed out, it seems that the media has not been set up correctly. The easy way to get "started" is just to buy the media already installed on it. Then learn how to get yo own media setup after you know it all works.

WRT power, if you are using a USB charger that barely meets the current requirements, the voltage may come up too slowly to allow a clean RESET of the SoC.

I've watched the voltage on an LG USB charger rated at
