Part Number: AM2432

Tool/software:

Hi Experts,

I have tried the example "watchdog_interrupt_am243x-lp_r5fss0-0_nortos_ti-arm-clang" on AM243x_lp and it works.But it does not work normally on a board using AM2432.What may cause this?Any need to change the syscfg file?

    By the way,I have changed the "WDT Expiry Time In Millisecond(ms)" to 10000,1000 and 100,and it triggered the "watchdogCallback" in 1000 seconds,840 seconds and 995 seconds respectively in real.What's the problem?

    Hello sigong,

    Are you resetting the SOC, either POR or WarmReset before loading an new WDT expiration change example from CCS?

    If you don't do POR or Warm Reset the SOC for every new change of watchdog expired time, then try POR or Warm Reset and load the example with the updated expired time from CCS , since once the watchdog timer is started, we can't stop it.

    Regards,

    Anil.

    Hi Anil,

    I followed your advice -- repower the SOC before loading a new example every time,and it worked.Thank you.
