HI,

I want to use in the disable the RTC of AM335x.

I am using the TPS65910 as PMIC.

It becomes the connection, such as the following in TMDXEVM3358.

PWRON : open

PWRHOLD : PMIC_POWER_EN(AM335x output)

＊I believe that it is not available when PMIC_POWER_EN you have to disable the RTC.

 

You are connected to the +5 V PWRHOLD pin in order to activate the TPS65910A after turning of +5 V According to an article in the E2E below.

What do I need to connect to PWRHOLD Pin? Sure you want a +5 V?
