This is a fairly USRP-specific question, unrelated to Gnu Radio in
particular.

This type of question belongs on the usrp-users mailing list.

I don't own an N321 myself, but I've always just used a
full-system-image update on my N310:

I'd strongly suggest joining the usrp-users mailing list for this type
of question, however.
