HackRF 2021.03.1 Release Notes
|
|
|
|
To upgrade to this release, you must update libhackrf and hackrf-tools on your
|
|
host computer. You must also update firmware on your HackRF.
|
|
|
|
Major changes in this release include:
|
|
|
|
- CPLD bitstreams are now included in and loaded automatically by the firmware.
|
|
There is no longer a need to update the CPLD separately.
|
|
|
|
- The clock output (CLKOUT) is now turned off by default.
|
|
|
|
- A new utility, hackrf_clock, provides a way to inspect and modify
|
|
configuration of hardware clocks, including turning on and off CLKOUT.
|
|
|
|
- The rad1o badge is now supported by firmware in this release. Firmware from
|
|
the HackRF release/repository is different than the original CCCamp firmware
|
|
and only supports operation as a USB SDR peripheral.
|
|
|
|
- When using a HackRF One with a PortaPack in "HackRF Mode" (operating as a USB
|
|
peripheral), the PortaPack display now indicates operational status and
|
|
settings.
|
|
|
|
There have been many more enhancements and bug fixes. For a full list of
|
|
changes, see the git log.
|
|
|
|
Thanks to Jared Boone, Dominic Spill, schneider, and Mike Walters for major
|
|
contributions to this release!

HackRF 2018.01.1 Release Notes
|
|
|
|
This is a firmware maintenance release that improves reliability of HackRF One
|
|
when booting from the DFU bootloader. If you do not frequently use DFU boot,
|
|
there is no reason to upgrade to this release.
|
|
|
|
|

==============================
|
|
HackRF 2017.02.1 Release Notes
|
|
|
|
To upgrade to this release, you must update libhackrf and hackrf-tools on your
|
|
host computer. You must also update firmware on your HackRF. It is important
|
|
to update both the host code and firmware for this release to work properly.
|
|
If you only update one or the other, you may experience unpredictable behavior.
|
|
|
|
Major changes in this release include:
|
|
|
|
- Sweep mode: A new firmware function enables wideband spectrum monitoring by
|
|
rapidly retuning the radio without requiring individual tuning requests from
|
|
the host computer. The new hackrf_sweep utility demonstrates this function,
|
|
allowing you to collect spectrum measurements at a sweep rate of 8 GHz per
|
|
second. Thanks to Mike Walters, author of inspectrum, for getting this
|
|
feature working!
|
|
|
|
- Hardware synchronization: It is now possible to wire the expansion headers of
|
|
two or more HackRF Ones together so that they start sampling at the same
|
|
time. This is advantageous during phase coherent operation with clock
|
|
synchronized HackRFs. See the -H option of hackrf_transfer. Thank you, Mike
|
|
Davis!
|
|
|
|
- A new utility, hackrf_debug, replaces three older debug utilities,
|
|
hackrf_si5351c, hackrf_max2837, and hackrf_rffc5071.
|
|
|
|
- Power consumption has been reduced by turning off some microcontroller
|
|
features we weren't using.
|
|
|
|
There have been many more enhancements and bug fixes. For a full list of
|
|
changes, see the git log.
|
|
|
|
Special thanks to Dominic Spill who has taken over much of the software
|
|
development effort and has helped with nearly every improvement since the
|
|
previous release!

HackRF 2015.07.2 Release Notes
|
|
|
|
Bonus release! This release contains fixes for CMake configuration bugs that
|
|
affected installation of 2015.07.1 on some platforms.
|
|
|
|
|
|
==============================
|
|
HackRF 2015.07.1 Release Notes
|
|
|
|
To upgrade to this release, you must update libhackrf and hackrf-tools on your
|
|
host computer. You must also update firmware on your HackRF. It is important
|
|
to update both the host code and firmware for this release to work properly.
|
|
If you only update one or the other, you may experience unpredictable
|
|
behaviour.
|
|
|
|
Major changes in this release include:
|
|
|
|
- Multiple HackRF support. Users with more than one HackRF can target a
|
|
specific device from software using the device serial number. The serial
|
|
number is easy to find with hackrf_info. Thanks, Hessu!
|
|
|
|
- Linux kernel module detaching. A work-around to avoid the unofficial HackRF
|
|
kernel module in recent kernel versions that has been causing problems for
|
|
many users.
|
|
|
|
- Updating the CPLD is now possible from Windows. There is no CPLD update with
|
|
this release, but Windows users should now be able to update.
|
|
|
|
- Support for rad1o hardware, the badge of CCCamp 2015 based on HackRF One.
|
|
This package contains host software supporting rad1o; for firmware and other
|
|
resources, refer to: https://rad1o.badge.events.ccc.de/
|
|
|
|
There have been many more enhancements and bug fixes, for a full list of
|
|
changes, see the git log.

HackRF 2014.08.1 Release Notes
|
|
|
|
To upgrade to this release, you must update libhackrf and hackrf-tools on your
|
|
host computer. You must also update firmware and the CPLD. It is important to
|
|
update both the firmware and the CPLD for this release to work properly. If
|
|
you only update one or the other, you may experience an inverted baseband
|
|
spectrum.
|
|
|
|
For a complete list of changes, see the git log. Highlights include:
|
|
|
|
- HackRF now uses high side injection when tuning to frequencies below 2150
|
|
MHz. This significantly reduces images on both RX and TX that resulted from
|
|
harmonics of the front-end local oscillator. If you ever wondered why you
|
|
were picking up broadcast FM stations at frequencies well outside the FM
|
|
broadcast band, they were probably such images.
|
|
|
|
- A CLKIN firmware bug was fixed. The bug prevented switching to the external
|
|
clock source. Switching now works automatically at the start of every TX or
|
|
RX operation. If a clock signal is detected on CLKIN, that external source
|
|
is used. If a clock signal is not detected on CLKIN, the internal crystal is
|
|
used.
|
|
|
|
- hackrf_transfer now has a signal source mode that transmits a CW signal.
|
|
Thanks, dovecho!
|
|
|
|
- The optional udev rules file was moved from hackrf-tools to libhackrf.
|
|
|
|
|

==============================
|
|
HackRF 2014.04.1 Release Notes
|
|
|
|
To upgrade to this release, you must install updates to the software on your
|
|
host computer including libhackrf, hackrf-tools, and any other software (e.g.
|
|
gr-osmosdr) that uses libhackrf. You must also update firmware and the CPLD
|
|
(which should be updated after firmware and host software is updated).
|
|
|
|
For a complete list of changes, see the git log. Highlights include:
|
|
|
|
- The sample format has changed from unsigned 8 bit integers to signed 8 bit
|
|
integers. This affects all HackRF software and changes the file format used
|
|
by hackrf_transfer. If you need to convert a file from unsigned bytes to
|
|
signed bytes, I recommend sox:
|
|
|
|
$ sox old.ub new.sb
|
|
|
|
- HackRF One is now supported and is the default target platform when compiling
|
|
firmware. To compile firmware for Jawbreaker, set the BOARD variable:
|
|
|
|
$ make -e BOARD=JAWBREAKER
|
|
|
|
- HackRF One hardware design and documentation are complete. It is now the
|
|
preferred platform.
|
|
|
|
- Automatic clock synchronization is enabled in the firmware. To activate
|
|
clock synchronization, simply connect an SMA cable from CLKOUT on one HackRF
|
|
One to CLKIN on another HackRF One. The clock signal is a 10 MHz square wave
|
|
at 3.3 V DC. This also works on Jawbreaker but requires the installation of
|
|
SMA connectors and a few other components noted in the schematic diagram.
|
|
|
|
- The automatic tuning algorithm is improved for frequencies above 2150 MHz.
|
|
The algorithm (in firmware) automatically avoids spurs caused by harmonic
|
|
relationships between oscillator frequencies in the analog RF section.
|
|
Similar improvements below 2150 MHz will require further effort.
|
|
|
|
- An explicit tuning option is now available to select tuning parameters
|
|
different from those chosen by the automatic tuning algorithm. Automatic
|
|
tuning should be preferred for most use cases, but advanced users can use
|
|
explicit tuning when there is a need, for example, to avoid a particular
|
|
local oscillator frequency for a specific application. Explicit tuning is
|
|
implemented only in hackrf_transfer so far.
|
|
|
|
- Antenna port power on HackRF One can be enabled or disabled during RX or TX.
|
|
This is implemented in hackrf_transfer. When activated, 3.0 to 3.3 V DC is
|
|
supplied to the antenna port. This can safely supply up to 50 mA, enabling
|
|
equipment including some active antennas.
|
|
|
|
- The firmware compilation and installation instructions have changed. See
|
|
firmware/README and firmware/cpld/README for details.
|
|
|
|
Known bug: CPLD update does not work on Windows. See:
|
|
https://github.com/mossmann/hackrf/issues/113
|
|
|
|
Many thanks to Ben Gamari and Jared Boone for their considerable efforts to
|
|
improve the firmware in this release!

HackRF 2013.07.1 Release Notes
|
|
|
|
A firmware update is required to take advantage of features of this release and
|
|
for compatibility with future software based on this release.
|
|
|
|
For a complete list of changes, see the git log. Highlights include:
|
|
|
|
- DC offset correction (greatly reducing the spike seen in the center of an FFT
|
|
display)
|
|
- Intermediate Frequency (IF) selection
|
|
