In the OEM Product Design Guide for the AGX XAVIER SoM the usage of a RTC backup is mentioned as optional.
Further it is said, that the SoM-side PMIC (MAX20024) needs to be configured for such an implementation.
How do I do that?
E.g.: Max. voltage rating = 3.3 V / ESR = 200 Ohm / C = 0.2 F / Max. charged voltage = 2.8 V
Thanks in advance.
PS: The datasheet of the PMIC is not available at MaximIntegrated; it also seems to be EoL. :(
PPS: Here in the forum, one said, that there might be a RTC backup on the SoM too? Can one confirm this?
