[SOLVED][Odroid C2]: Repeated errors in dmesg, bug or feature?

cosmos · Jan 22nd 2018

I am receiving a lot of errors constantly repeating every second or so on my Odroid C2/official LE 8.2.2, when running dmesg:

Is this normal behavior?

Possibly a bug, see: pcf8563_get_datetime: read error

Does your C2 have an RTC shield fitted?

cosmos · Jan 24th 2018

No, it doesn't.

**chewitt** · Jan 25th 2018

That will be why you see error messages about the RTC not initialising then.

Thanks. I followed a workaround described in the link above, and worked fine. Consider this thread solved as well.
