look for the delay rootine add a _nop()
of course should have been
look for the delay routine add a _nop()
Actually, burp master, you meant
__nop() ;
(note the extra "_"). Details are rather important, you know.
just to verify that a change in the delay routine will do it, add 10 _nop()'s, if so, you can later calculate how many are needed.
If I suspect a delay and there is no reason to limit it, I always makes it huge for debugging purpses.
