What is the difference when starting with the debugger instead of reset

[simonteki]

Hi,

I am working with KDS 3.0.0 with the TWR-K60F120M and my project works if I use the gdb debugger. But as soon as I have an reset the SW get stuck in an undefined area (No source available for "0xfffffffe" ) and the reset light on the board is half lit. Can the use of the interrupt vectors in RAM cause such problems? As the reset vector isn't handled correctly?

Ok, it is definitely a problem with the interrupts in RAM. Even if I use the PE generated code for it, it fails after a reset. Any ideas what I am missing? Shouldn't' it jump to address 0 and start up normally?

Hi

did you ever perform vector relocation in your application?

Have a great day,

Yes, and the interrupts work correctly but I think I found the problem. The interrupts seem to be only in RAM so after a reset the beginning of the flash is "empty". It seems like that with the debugger a different start address is used and that confused me :smileyhappy:
