Sitara Support Team,
My customer is facing that the WDT operates about 20% faster than the set time
on the custom board with AM4372.
When set to 10 seconds, it activates in 8 seconds, and when set to 20 seconds, it activates in about 16 seconds.
To measure the operation time, the LED mounted for debugging is turned on at the timing to enable WDT,
and the time until reset (LED off) is measured with a stopwatch.
The source clock and register settings seem to be fine.
Could you please point which registers he needs to check?
Is it possible to measure the actual WD Timer Clock Signals; PI_OCP_CLK and PI_SYS_CLK
because they are internal clocks?
Best regards,
Kanae
