raspi cam not working

I get the same error 1:ENOMEM when using the raspistill program plus
mmal: Camera is not detected. Please check carefully the camera module is installed correctly

I made sure that the flat ribbon was inserted properly and even replaced the cam/ribbon with a new one since I thought it was defect.

Further I increased the memory to 256k (GPU in config.txt) and searched for this issue online beofre posting my request here. There were a few posts in the raspberry forum about this issue where they said that the GPIO and I2C bus clashes (2013). Since I have not seen anyone else with this issue in this Atlas3D forum, I thought it was a defect camera so replaced the cam with a new one but still the same issue.

Not sure if this additional info helps:
- After trying with no results: I used raspi-config to enable the camera and the advanced settings (I2C, SPI) with no results.
- When I start up the Pi, the cam led immediately turns on and always stays on.
- I have tried raspicam with just the Pi without the step electronics (GPIO) which returns same error
- It is a Pi B+ (version 1.2). I had the Pi working on a SD card previously before the kit arrived. After I insert the old working sd card, it refuses to boot. Just a # command turns up in the screen (HDMI).
- Finally I have updated the Pi with the latest distro and boot with as result same error but freelss does not start automatically anymore. Should I re-image a SD card with your distribution image? (not sure how to get that image)

hope this helps with the identification of the issue....

Hi Uriah,

the camera is in the correct slot but the led on the cam is not turning on (it only flashes shortly after a boot so it seems to be connected). I followed the instructions from and RPI site (video) to the letter. The connection strip on the ribbon is facing the right way.
I upgraded the RPI to Jessie to see if it makes differences but not. So either the Pi is broken or the Cams. I have another Pi at work so will try it there with the camera's.
Can you let me know how I can get the original image for the SD? I might put that on another SD card and see if it makes a difference. Another issue I have is the WiFi which is not working. Probably because of my upgrade it lost its original drivers. I will look into that once the camera is working. I can live without it...:)

Thanks heaps!

Something is wrong with either the camera or the Pi.

Today I verified the issue with a new Pi 2  and this works flawless. So the Pi B i got is definitly a very old stock item which firmware is not compatible with the raspicam. Anyway I happy now and can start calibrating the scanner. I quickly verified the webserver which brings up freelss and all components like lasers and cam seems the work well.
