AM3352: Last time power was turned off

Part Number: AM3352

Hi Experts,

About AM3352, is it possible to get the last time the power was turned off?

Is it saved in a register (or) do we need to configure something to get the time stamp when the device was last powered off?

Thank you.

Regards,
Archie A.

    Hi Archie,

    I don't think there is a register for it, all SoC content is lost when power is gone, isn't it?

    The easy way I can think of is to create a userspace application which just writes a mark message to syslog periodically, the interval depends on the accuracy of the time stamp the customer wanted. Then next time power on the board, just check the timestamp of the last message in syslog.
