J721EXSOMXEVM: Configuring Watching on a Jacinto 7

I'm looking to configure basic watchdog functionality on the two A72 cores that would just reset the device.  Is there anywhere an example of configuring the WWDT on RTI0/1 for this?

    Hi Brian,

    The PDK has some reference code at the below locations:

    ..../packages/ti/csl/src/ip/wd_timer/V0/priv/wd_timer.c

    .../packages/ti/diag/sdr/src/sdr_wdt.c

    .../packages/ti/diag/sdr/test/sdtf-test/src/sdtf_wdt.c

    This code is not targeted at the A72 cores, but should be useful as a reference.   

    Regards,
