Using LPCXpresso 7.9.0 Free Version with Segger J-Link on LPC2378 ARM Chip and cannot get Breakpoints to work

The program will debug and flash to the chip but it basically ignores breakpoints that I set. When I pause the program it jumps to a little assembly code in the startup program. I can't get it to do anything else and I'm not seeing any feedback.

Any tips on this?

Where exactly do you end up in the startup code? And what happens if you "resume" execution at that point?

It might also be worth booting your board into ISP mode before you start your debug connection.

It jumps to src\cr_startup_lpc23.s and stops on line 132: LDR pc,_swi //SWI/SVC

So did you try resuming?

And did you try booting into ISP mode before starting your debug session?

I have a J-Link Plus and use it to debug LPC1769. I had similiar experiences. Eventually I solved it by switching off all compiler optimizations. (-O0 option) I was triggered by similar experiences I had with Segger SAM-ICE for Atmel. Hope this helps...
