Watchdog fails when executing IAP functions: LPC2131

Sankesh Hilot

Hi
I am using LPC2131 chip and i have problems while using IAP functions.
1) Watchdog Reset does not happen if the program hangs while executing the IAP function.During normal operation watchdog works fine.
2)I am using IAP function repeatedly but CPU hangs after some point of time,has anyone faced this kind of problem ,pls let me know
Thanks

    Hello,

    During normal program execution IAP calls is working fine,but if we use IAP calls repeatedly(Say we are doing a repeadted flash write every 5 seconds;Same data,same sector) then after 40-50 sucessful execution CPU get hung. We want the Watchdog reset to happen whenever CPU hangs.WatchDog reset works fine during malfunction of any other module except IAP.

    Thanks,
    Sankesh
