Pause

Pause

[Russell Shaw]

Hi,
I set up .gdbinit so that with a single command, gdb can
load a new file to be debugged, and start a simulator:

define simul
     detach
     shell killall -sHUP simulavr
     shell simulavr -g -p 4242 -d atmega16 -c 16000000 loader_02.bin &
     file loader_02
     target remote localhost:4242
end

This works ok if i type one line at a time. If i type "simul", the
commands happen too fast and gdb gives an error message before the
simulator has started. Does gdb have a "pause" or delay command?
I need one here:

define simul
     detach
     shell killall -sHUP simulavr
     shell simulavr -g -p 4242 -d atmega16 -c 16000000 loader_02.bin &
     file loader_02

     < delay 300ms >

     target remote localhost:4242
end

There is nothing predefined, but as a workaround you could use a counting
loop.  Of course, you need to calibrate it first.

       set $i = 0
       while ($i++ < 100000)
       end

On second thoughts, i'll modify simulavr so that it sets itself up
properly before it forks (instead of using the shell fork &).

Would "shell sleep 1" do the trick?  (If 1 second is too long, you
could write a simple program that called nanosleep or some such to
sleep with finer granularity.)

shell sleep 1 should work well. Thanks.
