Part Number: AM4372

Hi all,

I have the following question about how to control RTC_PMIC_EN pin of AM437x.

Q1) In order to make RTC_PMIC_EN Low, I think it is necessary to use the ALARM2 event.

But I'd like to know if there is a way to control it more easily. Can I turn this pin low in other ways?

Q2) It is only ALARM 2 event that this Pin can be set to Low.

Is there a sample program?

Best regards,

Sasaki

Hi,

Q1: No, there is no other way to set this pin low.
Q2. Check the Linux "poweroff" command.

If there is one, I'd like to know non OS's example code.

TI does not have non-OS examples for this processor.
