Q&A Disabling breakpoints in real-time section of firmware

I have a similar problem when debugging firmware on a dsPIC that drives a flyback power supply. The switch isn't designed to be on for very long, as eventually the inductor saturates. Usually the...

Q&A Disabling breakpoints in real-time section of firmware

Breakpoints are beyond the scope of the C language, so this is up to the specific debugger and CPU core. What you will probably have to do to block accidental breakpoints is to not provide any debu...
