RTC Aurix and power supply

Hi,

I have a problem with RTC on Aurix, on every power cycle it get’s reset to some default time. Is there a battery inside PX2, or it has to be under power supply all the time to preserve time?

Dear anja,

There is no RTC included in DRIVE PX 2. Thanks.

So the only way to preserve time on Aurix is to shutdown tegra A and B from Aurix (power ab off) and keep the Aurix on?
If so, how much power does Aurix consume?

Dear anja,

Regarding time sync, please refer to below link. Thanks.

Hi,

I’m familiar with this procedure. But if the device is in the car, should I connect every day to Aurix serial port and adjust the time and that sync PX2 with Aurix like in the guide you send me? I would like to turn off PX2 with the car, but also to preserve time, so the day after I don’t have to sync time again.
