Re: [beagleboard] RTC Time Suspended Between Power-Ups
Hi, You're referring to the Beaglebone Black though right? This is the XM that I'm talking about.

You are correct. My bad, 99% of the posts here are BBB related. On 11/1/2014 1:35 AM, Ben Collier wrote: Hi, You're referring to the Beaglebone Black though right?

Re: [beagleboard] RTC Time Suspended Between Power-Ups
That thread looks as though it covers the Beaglebone Black, rather than the XM. Is the principle the same for both devices, or is it completely different?
