Hi TI,
Q1.
If the LEOA_WDOG_DISABLE pin of PMIC is LOW (Enable WDOG),
How to disable PMIC WATCHDOG in software ?
Q2.
How to feed the PMIC WATCHDOG in software ?
in R5 ?
in A72 uboot code ?
in A72 kernel code ?
Q3.
How to change the timer of PMIC WATCHDOG in software ?
Now it trigger reset after about 13 minutes.
How to change it to 5 minutes ?
Q4.
Is there a software service to feed the PMIC WATCHDOG ?
How to enable the software service ?
Q5.
Is there a document like lp876242-q1.pdf to show the PMIC WODG of TDA4AL-Q1 ?

We have already have a solution for the TDA4, https://www.ti.com/lit/ug/slvuci2/slvuci2.pdf?ts=1740083844958&ref_url=https%253A%252F%252Ftexasinstruments.seismic.com%252F
Above is the User's guide for a single PMIC solution, the Software Development Kits for the TDA4 will contain the software necessary to use the WD.
The details of the WD are in the datasheet for the TPS6594133A, TPS6594-Q1 Power Management IC (PMIC) for Processors with 5 Bucks and 4 LDOs datasheet (Rev. B)
