AM335x EVM RTC

Z Ha

I'm testing the RTC example project from StarterWare_02_00_00_07 (CCS projects) on the AM335x EVM and noticed that it doesn't keep time between power cycles; why is that happening?

Thanks

Which EVM are you using?

For Starterware please direct your questions to the dedicated forum: http://e2e.ti.com/support/embedded/starterware/default.aspx

HI，

You're right. The AM335X's internal RTC will lost all your settings when the board powered off. If you really want to have a running RTC whether your board is powered on or not , you should use an external RTC or try to connect a battery to your PMIC. But i think the former is easier.

If my answer meets your question , please click yes. Thank you.
