My computer is a SAM460EX. I'm using the latest SDK with OS4.1.4 with Cubic IDE. I'm working on a rather large project. I have an almost identical setup on my microA1. What happens is when I use gdb to debug it and set a breakpoint, it will stop at the first breakpoint, but will ignore any additional breakpoints. I haven't had my SAM long and so haven't tried debugging before. My micro behaves normally, stopping at breakpoints when it comes to them. I'm wondering if anyone has run into this before. The project is written in c++.
