Installing ghpsdr3-alex on Raspberry Pi

I recommend installing either the raspbian or raspbian pisces distributions as there is no Ubuntu release to date.

All the pre-req packages mentioned for the Ubuntu installation are also needed for the Raspberry Pi and are available using "apt-get install" as usual.

    • The RasPi USB subsystem is sensitive to power supply voltage levels - A supply of 5.25V at 2A is recommended. With +5.17V I was getting on-board Ethernet errors and system hangs when one more device besides keyboard and mouse were plugged in to the on-board USB ports or an outboard powered USB HUB. Increasing the voltage to +5.27V solved the problem.
    • Do not use power from a USB PC port or from a USB Hub.

Once it's up and running, some details that may help in setting up the hardware for use - I'm currently overclocking at 1GHz:-

I had originally forgotten to add snd-bcm2835 to /etc/modules which is why the SB Live! 24 is card 0. Rebooting with just the on-board sound card then adding the SB Live! 24 USB changed the on-board to card 0 and the SB Live! 24 USB is now card 1. I have further tests to do, mainly with sound, but now the Rpi is looking much healthier.

== Headline text == * SOFTWARE * If you build ghpsdr3-alex already it's a case of following the same procedure with the following caveats that apply to the RasPi ARM architecture. What follows is a blow by blow account of how I did it for the iw0hdv branch which supports my HiQSDR+Preselector.

Subject: [n2adr-sdr] Raspberry Pi running ghpsdr3-alex

I did a fresh clone and changed to the iw0hdv branch from the default master branch.

  1. git checkout iw0hdv

Removed all traces of -msse, -msse3 and -ffast-math from and where appropriate in the subdirectories.

  1. autoreconf -i
  1. ./configure CFLAGS='-O3 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard' CXXFLAGS='-O3 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard'

  1. make all && make all install

Running hiqsdr-server at 48K/96K and dspserver (built with qt4) as qt5 is not yet available. There are instructions for building qt5 but following them bullet by bullet it failed not far along. The instructions are for building on i386 - I have put out a request for .deb packages or at least built tarballs to the Raspberry Pi forum.

QtRadio running on another box using the connection from the server list. Sound is a touch distorted, quite distorted on start up of QtRadio and spectrum is always a little bit slow.

When a slave connected and tried changing frequency, dspserver crashed - dspserver can be a bit crash happy.

The first thing I tried on the Pi was QtRadio standalone, spectrum and waterfall were OK but no sound.

Just now a client using glSDR (5) is attempting to change frequency, sound went quite distorted then dspserver crashed.

Restarted dspserver and QtRadio sound started very distorted before it settled down to reasonable.

Installing on ODROID-X and Pandaboard

There are 2 Ubuntu images downloadable from



The image needs to be decompressed e.g:- "gzip -d odroidx_20120906-linaro-precise-ubuntu-desktop_with_HDMI.img.gz" then burned on to a SD card (full size or microSD with a full size adaptor).

"dmesg" will tell you what it's called when you attach the reader with the SD card inserted to a USB port,e.g /dev/sdb, /dev/sdc, etc.

"dd if=odroidx_20120906-linaro-precise-ubuntu-desktop_with_HDMI.img of=/dev/sdc bs=1M"

When it completes, insert the SD card into the ODROID-X and boot up - the ODROID-X has a power on and a reset switch on board.

There is a way to prepare the SD card using Windows but I don't do Windows, consult for a link to "dd" for Windows.

I use the HDMI.img as I have a spare HDMI port on one of my monitors - it requires a micro HDMI cable, standard HDMI on the monitor end and micro HDMI on the ODROID-X board.

When you have the ODROID-X all up and running and installed the pre-req packages for ghpsdr3-alex - there are a lot of them as is the case with any Ubuntu or other distribution, the build instructions are as follows:-

$ git clone git://

$ cd ghpsdr3-alex

Then I run a script to remove -msse and friends, the script I call "rm_words" made executable and put in /usr/local/bin

find ./ -type f | xargs sed -i 's/-msse3//g'

find ./ -type f | xargs sed -i 's/-msse//g'

find ./ -type f | xargs sed -i 's/-ffast-math//g'

autoreconf -i

source set_Qt-5.0.0_path.src

set_Qt-5.0.0_path.src contains "export PATH=/opt/qt5/bin:$PATH" and I'm using the qt5-daily from edgers. precise main

The configure script I call "alex-config" made executable and put in /usr/local/bin

./configure CFLAGS='-O3 -pipe -mfpu=neon -fno-tree-vectorize -fopenmp' CXXFLAGS='-O3 -pipe -mfpu=neon -fno-tree-vectorize -fopenmp'

$ make -j 4 all

$ sudo make -j 4 all install

The ODROID-X is treated the same as the Pandaboard and the Raspberry Pi when building ghpsdr3-alex, except the Pandaboard uses the normal Ubuntu ARM distribution while the ODROID-X uses the linaro Ubuntu ARM distribution built especially for it. The Raspberry Pi uses the debian raspbian distribution.

The distributions are all Ubuntu ARM and packages are updated, upgraded and installed in exactly the same manner as Ubuntu for x86/x86_64 so there is no learning curve involved if you already know Ubuntu.

I use 32GB Class 10 (the fastest) SD cards but recommend at least 16GB to give ample space to install and build other software. SD cards can either be full size or microSD in a full size adaptor.

I have been running hiqsdr-server, dspserver and QtRadio on the ODROID-X for a few weeks 24/7.

"dsploop" by Alex has stopped the dspserver crashes that periodically occurred on all platforms.
