Hi group,
We have a number of custom boards (based upon the dev server 83+ design) and we are having a problem with one particular board.
The problem is that the MCM (4+16) on this board crashes after a couple of minutes/hours uptime.
At first I thought it was the custom SW that caused this, so I ran a test without the SW and it ran (just idle) for a more than a day.
It must be the SW you would think (me too at first), but this morning I ran a test with a simple shell script (while true do; find /; done;)
and after a couple of minutes the MCM crashed, so that rules out the custom SW.
We also experimented with different environments to test if the problem was heat related but no change;
We have replace one or two MCM in the past because those refused to program.
Boards got x-rayed and no short we found :(
However this board shows a different behaviour.
Any ideas or similar problems ???
Regards,
Peter
