does IMX8MP evaluation board have a RTC ?

Hi all,

I have an NXP evaluation board for i.MX8M plus processor, and at every reboot I have to set again time and date.

There is a way to keep date and time with RTC or maybe there is other solution... it is quite annoying.

Regards,

Are you using NXP evk board? Which version BSP are you running on your board?

yes, I am using your NXP evaluation board.

I did some other tests with LF_v6.6.3-1.0.0_images_IMX8MPEVK, and I see that hwclock mantains time & date only if I don't turn off PWR switch.

I suppose that there is a built-in RTC, but it is without battery. Is it right?

If it is, there is a way to connect a battery ?

Francesco
