How to test a Pi

Tue Jul 09, 2013 8:42 am

I have 4 Pi's, 3 revision 1 and 1 revision 2. The old rev 1's work fine but I am havving trouble with the rev 2 crashing.

Are there any tests that I can run to test for a hardware problem with the Pi?

Is there any reason why an SD card from a rev 1 should not work in a rev 2 or vice versa?

There was a firmware upgrade between release 1 and 2 to cater for the newer memory chips.

Try downloading the latest Raspbian and flashing that to your SD card.

Note: that the updated card should work fine with the older boards.

Different memory chips could do it. If all are Hynix and one is Samsung an older image might have a problem. http://www.raspberrypi.org/archives/3534

I am using the latest image, downloaded a couple of days ago and installed via NOOBS.

Linux pi-f 3.6.11+ #474 PREEMPT Thu Jun 13 17:14:42 BST 2013 armv6l GNU/Linux

I am assuming that this image should work on any Pi, is that correct?

If you think it might be a power issue you can get a multimeter and go through this procedure;

It is a genuine RS recomended power supply, just checked and 4.96 volts, so not a power issue it seems.

Are there any utilities for running memory tests etc?
