Using the blinky example code, if I put a breakpoint in the systick isr and then reset the target using the debugger with the core stopped on that instruction, the isr never fires again. I have to exit the debugger and physically reset the core.
Putting the breakpoint anywhere else does not have the same effect. Interrupts work perfect after the reset.
Putting the breakpoint in the isr but not resetting the core using the debugger whilst the core is stopped doesn't trigger the fault either.
All settings are as default used in the demo code.
Has anyone else noticed this?
