does rtems 5.1 support create a core dump file when accessing a invalid address or other fatal errors?

Saving crash data to a flash disk is normally a bit too complex and 
involves interrupts and DMA. I would save the crash data to a volatile 
memory area which survives a soft reset. After the soft reset, check if 
crash data is available and save it to the disk.
