Cannot get pi to work

Tue Aug 20, 2013 7:31 am

I am completely stumped with this issue. I received my first raspberry Pi a few weeks ago and followed the quick start guide to the T to try to start up my Rpi for the first time and no dice. I have downloaded the latest NOOBS and formatted the card. When I plug the power in the green light flashes for a few seconds and then it stops and no display. I have tried using keys 1and 2 for the HDMI and 3 and 4 for composite (separately). Only thing I have plugged in are the keyboard, mouse, and display cord. Also the cord I use for power is one of the cords recommended by Newark. Could it be something wrong with the Pi?

what are the contents of your SD card
don't bother with a mouse yet
which keyboard are you using - post a link to the type
which PSU are you using - post links
can you try the composite output

Ok no mouse for now,
I am unable to check the contents of the card at this moment, however all i have done is download NOOBS and using Winrar i exported the contents of the folder to the newly formated 8G SD card.
Keyboard is the logitech K120 http://www.amazon.com/Logitech-920-0024 ... s=keyboard
PSU is MCM - MWS5-0501000UC/M - AC-DC CONV, EXTERNAL PLUG IN, 1A, MICRO-USB

And i have attempted to use the composit output.

how did you write the images to the SD card , and using that computer you should be able to check what it on there,
also it may be worth truing the raspbian image

Hi there! If noobs doesn't work for you can you try it the old way?
This is where you download one of the raw images, unzip the zip file (this will give you a .img file) and then you burn that .img directly to the SD card. You can use a Windows program called Win32DiskImager to do this (see link below). Try it that way and see if it works.

http://elinux.org/R-Pi_Troubleshooting

Usual suspects are -

inadequate power supply

incorrectly written SD card

SD card not making complete contact with the sd card slot in the RPi.

In respect of NOOBS - does the sd card have a top-level folder/directory named 'Noobs', or 'Archive' or anything similar? Because it shouldn't! The top-level of the card should contain 2 directories named /images and /slides and about 6 other files - that's all. These files should be visible when read by a Windows PC, mac, or other linux system.

all the card contains from NOOBS is what you have stated it should, and they are visible on windows, I posted a link to the PSU i use does anyone have any experiance with this PSU? Is it a good one or should i look for another and if so does anyone have any suggestions? and as far as the pins not connecting to the card how do i determin if this is the problem?

You mention the green LED flashes for a short while. If that is the case then the Pi is almost certainly booting OK and the issue is getting the Pi set up to recognise your display. The main thread discussing this is http://www.raspberrypi.org/phpBB3/viewt ... =91&t=5851. Many displays need entries in config.txt on the boot partition to help identify displays that are not very good in advertising their capabilities (or surprisingly often report them incorrectly).

It is possible that if instead of using the NOOBS distribution you use the latest Raspbian image written using something like win32diskimager may be better - it just might recognise your display without help.

This actually might be part of the issue, I have an AVOL tv which is not that well known of a brand.

So after following all of the advice i finally saw the initial set up screen. unfortunately my keyboard doesn't work with the Rpi. I believe drivers need to be installed with it to make it work. Any suggestions on a cheap keyboard that will work, plug and play?

Most cheap USB keyboards should work fine as long as they have no special features that might result in excessive current draw. I have seen one for just a few pounds in places like Tesco. I have some very small USB keyboards that are great for using a Pi in a mobile scenario.

I am surprised that you have a keyboard that requires additional drivers to work - what is the model you have?
