In traditional embedded RTOS land, "system-level debugging".
In the olden days one had to have BDM/JTAG hardware assist
to step thru truly arbitary bits of code, like interrupt handlers,
The original question was about using using a hardware debugger.
Clearly using gdb/gdbserver is for apps only, AFAIK. Does one
bother with a h/w debugger for apps? Using kgdb with some kind
of remote debug-agent would be a "system level debugger", a s/w
solution to a traditional hardware only debug aid. At this time
kind of pointless, as its painful to setup and JTAG debuggers
are so cheap (for mainline CPUs).
