Command History
Usage Guidelines When the processor fault or exception occurs, the ROM monitor preserves the processor context at the
time of the fault. The
context command displays this processor context, which includes information
about the kernel registers and the process mode of the booted image (if available).
Examples The following example shows how to display the CPU context at the time of the most recent fault or
exception:
rommon 21 > context
