Does anyone have any ideas as to why my LPC2129 program can reset without any exceptions occuring??? I know that all of my exception routines work because I have tested them all. IAP, FIQ and the watchdog have also been ruled out. Every once in a while the program will simply jump to the Reset_Handler, for no apparent reason.

Do you have your watchdog enabled ? How many interrupt sources have you enabled ?

The watchdog is not enabled and I have three interrupt sources; CAN1, Timer0 and UART1 which are operating normally. --- In lpc2000@yahoogroups.com, "Amit" <emailakb@y...> wrote: > > Do you have your watchdog enabled ? > How many interrupt sources have you enabled ? > > Amit > > --- In lpc2000@yahoogroups.com, "rjwal3" <rossjwalker@n...> wrote: > > > > Does anyone have any ideas as to why my LPC2129 program can reset > > without any exceptions occuring???

Are you handling spurious interrupts by progamming an ISR into the VIC Default Vector Address register? amit --- In lpc2000@yahoogroups.com, "rjwal3" <rossjwalker@n...> wrote:

No I have not done anything with VicDefVectAddr, you might have hit the nail on the head. --- In lpc2000@yahoogroups.com, "Amit" <emailakb@y...> wrote: > > Are you handling spurious interrupts by progamming an ISR into the > VIC Default Vector Address register? > > amit > > > --- In lpc2000@yahoogroups.com, "rjwal3" <rossjwalker@n...> wrote: > > > > The watchdog is not enabled and I have three interrupt sources; > > CAN1, Timer0 and UART1 which are operating normally. > > > > > > > > --- In lpc2000@yahoogroups.com, "Amit" <emailakb@y...> wrote: > > > > > > Do you have your watchdog enabled ? > > > How many interrupt sources have you enabled ? > > > > > > Amit > > > > > > --- In lpc2000@yahoogroups.com, "rjwal3" <rossjwalker@n...> wrote: > > > > > > > > Does anyone have any ideas as to why my LPC2129 program can > > reset > > > > without any exceptions occuring???

Yes the spurious interrupt stikes again.
