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:

to the boot procedure after breaking into ROMMON to ensure that all
hardware and software registers are in a known state before loading the new
image.
