- Subject: Masking interrupts during step
Is it possible to setup insight so that it masks interrupts during a
single step and then unmasks? My problem is that when I have interrupts
enabled and single step, I usually end up stepping into a isr such as
the timer interrupt rather than stepping to the next mainline
instruction. I think this is usually handled by the "rom monitor" or
debug stub running in the target, but I am using a jtag debugger
Macraigor mpDemon and have no special code in the target to help with this.
I have also observed that if I have at least my timer interrupt (10ms)
enabled and hit a breakpoint that it will not continue from that
breakpoint unless I either disable the breakpoint or disable the timer
interrupt. Not sure why this is.
