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.
We do not have the problem with the RTEMS-mvme5500 BSP. In that case,
I just have to debug and rewirte the software and reboot the CPU.
However, for vxWorks, I think you should be able to reload the initial
bootload and the
vxWorks boot yourself. Did'nt they send you the boot files ? I thought I
reload the
those vxWorks boot files myself serveral times myself many yeras ago.
Cheers,
Kate
Thanks in advance
