GDB speed using Remote Serial Protocol

["David Mc Kenna" <mckennad@esatclear.ie>]

Hi all,

At present I have an outline for a stub ( GDB RSP -> uController -> Jtag ) for
an Arm7TDMi. I have successfully implemented the GDB -> uController side of
the equation. Here I have two questions.

Is there another way of seeing what GDB sends to the serial port without enabling
debug info within GDB ?, i.e. without using the commands :
"set debug remote 1" & " set debug serial 1"

My second questions relates to the first. With debug info switched on ( "set
debug remote 1" & " set debug serial 1"), a single step talks < 1 second to
complete, including all the debug info being written to the screen. Yet when
I switch off this info the single step time starts at < 1 second but soon mushrooms
to ~ 5 seconds.

I have tried this on gdb v5 and gdb v5.2.1 with the same results.
GDB configured as arm-elf


Any ideas??

Thanks,
Dave
