Hi All,p

I am facing the following error.

1) setting up a breakpoint in a ISR results in the following error:

"terminating on communication loss: Pipe has been closed by GDB"

I solved the debug issue through this forum post:

I remove the -Xlinker option --gc-sections.

Upon doing this the debug session starts normally.

2) after the start of debug session I notice the ISR I declare (a 32-bit Timer 0 ISR) does not get invoked at all, and the code keeps jumping into the IntDefaultHandler ISR. This probably means the processor cant find the Timer ISR.

3) this problem seems to exist only when using my own project (LPCOpen C++ Project) where as the code in the samples seems to run and debug correctly.

Is this behavior right? Am I doing something wrong? If so, how do I fix it? Please help.
