I heard of VxSim...has anybody used this? thanks for any insights!

I am experiencing a very bizarre problem with vxWorks and I am hoping that someone might be able to offer some suggestions on where to start looking to determine the root of the problem. VxWorks is being used on a Synergy Microsystems VME SBC which is PPC based. The problem seems to arise at random times after rebuilding the OS image. For instance, by commenting out a single 'printf' stat...

Hi, I find that the stackpointer is pointing to 'bcopy' at the time of crash of my VxWorks application. This was found by analysing the log file and the Vxworks MAP files.

But, i find memcpy inside that routine (namely 'A'). Ques...
