Hello Team.

I want to use watch dog timer in my project. Following is my DevCfg_master_devcfg_out_cdb.xml  configuration for watchdog.

<driver name="Dog_Cfg">
  <device id="0x02000019">
    <!-- If this flag is set to 0x0, hw wdog and grace timer will be initialized -->
    <!-- If this flag is set to 0x1, hw wdog and grace timer will NOT be initialized -->
    <props name="dog_hal_disable" type="0x00000002">
    <!-- Grace timer value in sclk, This timer will declare a stalled initialization,
if intialization does not complete before it times out. -->
    <props name="dog_hal_grace_timer_timeout" type="0x00000002">
      160000 <!-- s*32000, 5s -->


Still result is negative.

Things I want to know.

1) How to Initialize and start WatchDog for QCA4020.

2) How to Feed WatchDog Timer.

Any example code would be helpful.

Thank you.

As per your configuration, watchdog is enabled. The property "dog_hal_grace_timer_timeout" is used to configure watchdog timer.

The QCLI demo demonstrates some of the watchdog functionality. You can refer to code in this path:
