A good source of info on this is the hackrf wiki :
https://github.com/mossmann/hackrf/wiki/Updating-Firmware

The latest releases are here: https://github.com/mossmann/hackrf/releases

Updating the firmware requires no coding, just running the tools.

[Hackrf-dev] Hack RF One - Ok or not?

[Robert Edwards]

A  question I would like advice on please. I have some basic C and Fortran but 
no python. 

I have bought a Hack Rf One. I might buy more if I can this one working.

From hackers_info on my terminal I get  

hackrf_info version: unknown
libhackrf version: unknown (0.5)
Found HackRF
Index: 0
Serial number: a06063c82520485f
Board ID Number: 2 (HackRF One)
Firmware Version: 2015.07.2 (API:1.00)
Part ID Number: 0xa000cb3c 0x00504764

on my iMac.

Is this ok or is my Firmware and librhackrf out of date and how do I fix that? 

Many thanks.

FWIW, dynamic range of the HackRF RX is limited by the 8-bit ADC, not by 
the analog front end. Maybe you could slightly improve noise figure with 
a better amp, but prolly not worth the trouble.

Re: [Hackrf-dev] Replacing the LNA/PA

[Chuck McManis]

Robert, are you looking to fix a broken HackRF or are you re-designing it
to eliminate the use of an obsolete part? If its the former, the part is
still available and if history is any guide it will continue to be
available in piece parts and lots of various sizes for several years.
