Airspy-Utils is a small software collection to help with firmware related operations on Airspy HF+ devices on Linux (and other free systems).

Why? For 'best results' it is often recommended to deploy the latest firmware. This small software utility collection helps Linux users with deploying the latest Airspy firmware.

UPDATE: The sole purpose of this work is to help out Linux users (like myself). I am NOT interested in starting licensing debates / controversies related to the upstream Airspy project. I am a just a new Airspy Linux customer who has zero knowledge about DSP (none is required for this work), and Airspy's previous history, behaviour, and origin.

• Airspy HF+ Discovery

This is the only Airspy device I have. Hint: Sponsorships can change this ;)

• Python 3.x

• A modern Linux distribution (Ubuntu >= 20.04 is recommended)

sudo apt install bossa-cli python3-pip airspyhf -y

git clone https://github.com/kholia/airspy-utils.git

cd airspy-utils

pip3 install -r requirements.txt

See firmware version:

$ python3 hfplus_fw.py
R3.0.6-CD

ATTENTION: Please verify if the firmware is BB or CD. This is IMPORTANT.

See firmware version:

$ python3 hfplus_fw.py  # after firmware upgrade
R3.0.7-CD

Backup calibration:

$ python3 hfplus_ppb.py -d > file

$ hexdump file
0000000 71b0 a5ca 0000 0000 0000 0000 0000 0000
0000010 0000 0000 0000 0000 0000 0000 0000 0000
*
0000100

Read calibration (ppb) value:

$ python3 hfplus_ppb.py -r
0

Write calibration (ppb) value:

python3 hfplus_ppb.py -w -p 0

Reboot device in bootloader (programming) mode:

python3 hfplus_reboot.py -b

In bootloader mode, running lsusb should show something like:

Bus 003 Device 016: ID 03eb:6124 Atmel Corp. at91sam SAMBA bootloader

Reboot device in normal mode:

python3 hfplus_reboot.py -n -p /dev/ttyACM0

Note: You may need to replace /dev/ttyACM0 with the actual value for your setup. It might be /dev/ttyACM1 for example.

Grab official firmware:

wget https://airspy.com/downloads/airspy-hf-flash-20200604.zip

unzip airspy-hf-flash-20200604.zip

cp airspy-hf-flash/hfplus-firmware-cd.bin firmware.bin  # ATTENTION: for devices using 'CD' firmware
# cp airspy-hf-flash/hfplus-firmware-bb.bin firmware.bin  # ATTENTION: for devices using 'BB' firmware

Full process to update the firmware (and restore the calibration):

python3 hfplus_reboot.py -b

sudo bossac -u -p /dev/ttyACM0  # you can try without sudo too

sudo bossac -e -b -v -p /dev/ttyACM0 -w firmware.bin

python3 hfplus_reboot.py -n -p /dev/ttyACM0

python3 hfplus_ppb.py -w -p 0  # use your own calibration value here
