[Hackrf-dev] Broken hackrf one after firmware update.

[Michael Ossmann]

You should also update the CPLD:

With new firmware and old CPLD I would expect the spectrum to be
inverted in some cases.  A fixed frequency offset would be puzzling
unless it is a misinterpretation of inverted spectrum (which could be an
easy mistake to make).
