LS1043 watchdog clock source

sedat_altun — Mon, 10 Feb 2025 19:43:59 GMT

Is it possible to make the watchdog functional on an LS1043-based custom board without an RTC clock input?

Can we set another internal clock source as the input to watchdog?

Thanks in advance

Hello,

Unfortunately, it is not possible.

The RTC functionality is clarified in the LS1043A Design Checklist, Table 42. Clock pin termination checklist:
"RTC is the only clock source for WDOG functionality."

Regards.
