Experimental Physics and
Industrial Control System

Hello All,

 

This is a problem which not directly related to Epics, but as several labs are using the MVME5500 CPU I hope that maybe someone has encountered this problem and has a solution!

 

Whenever a C program has a misbehaved pointer, which causes a memory-write outside the allocated data memory, we have a crash of the CPU which is absolutely understandable, but then, it is impossible to reboot the CPU. Both flash banks containing the initial bootload and the VxWorks boot are corrupted and the only solution is to send back the CPU to the retailer !!! We had experienced this with several CPUs (we are probably bad C programmers) and didn’t get so far any explanation from our retailers or after sales services. We have VxWorks 6.5.

 

Thanks in advance
