You probably want to set MEMMAP=2 BEFORE you download the code to make sure that the vectors are set.  

 

Try setting a breakpoint in the VIC handler.  

 

Obviously, if you have the code working from Flash, the VIC programming is correct.  My guess would be that either you are not loading up the vectors correctly at program load or you are corrupting your program when loaded in RAM.

Subject: [lpc2000] Timer interrupt when executing from RAM

 

Hi

I'm having a hard time making the interrupt work, when debugging my
code. When I debug, I run the program from RAM and use the arm-elf-gdb
to debug through a JTAG interface.

I've have set my MEMMAP = 2 and the code I'm testing works alright
when run from Flash.

Is there anything else I'm missing out regarding to interrupts when
running from RAM?

Best Regards
Søren
