Hello, I am using GDB to debug a program that includes RTEMS directives.
What I want is to set a breakpoint everytime there is a context switch (or a
task switch if you prefer it).
What do I have to enter after the "break" command in order to achieve this?
I have tried something like "break CPU_Context_Switch" (or variants of it),
but it doesn't seem to be working.

Thank you in advance.
