I can't see the reason in my code... I nearly exactly copied the Keil example and adapted it for my module and as long as no interrupt is generated everything works fine. I am using cygwin3.3, gcc3.3.3 and insight6.0 from www.gnuarm.com. I wrote my own startupcode and linkerscript, maybe the mistake is there would be nice if someone can send me another working example for gcc using timerinterrupts and simple led blinking. --- In lpc2000@yahoogroups.com, "jim_e_dallas" <jim_e_dallas@y...> wrote: > The address you referenced (0x7fffe2ae) is in the boot loader area. > Somehow your program must have jumped there or ran up to there.
