F3 Discovery: what is slow red flash on LD2

Question asked by constant.colin on Feb 4, 2015
Whenever my F3 Discovery board is powered by 5V (no USB) I get a slow red flash on LD2.  I can't find any info on what this means.  Maybe it just means there's power but no USB?

Thanks for your help,
Colin
