Raspberry Pi Forums

Hi All. First post.

I have one RPI I bought about 6 months ago, works a dream with any card I put in it and I use it for testing projects I'm working on.

The latest project requires 6 Pi's which I bought a few days ago. Brand new. Unboxed all of them and none of them boot the same card that works fine on my old one. The only difference I see is the date code on the back of the board.

Is there something simple I'm missing here?

A clean Noobs install works on ALL of them.

The Image I'm burning is this one: http://www.timschwartz.org/raspberry-pi-video-looper/
See SD card image.

Like I said, works fine when i boot it in my old Pi, just not in ANY of the 6 brand new ones.

Any help would be great...

Cheers..

Maybe your old Pi has RAM from a different manufacturer than your new ones? A fresh installation works because the software detects the RAM brand during installation and makes the necessary changes automagically.

It probably is, as GTR2Fan suggests, a Memory chip support issue.

You could try putting the old card in the old Pi and running sudo rpi-update to pull in the latest firmware to support the new (and old) memory. Although there are some issues with rpi-update at the moment which appear to be due to a clash between stuff on github and the current version of some software. Try it and see if it works. If it doesn't, search the recent posts on these forums for the work-around/fixes.

Thanks everyone! That did the trick....
