Talk:QtRadio Installation
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:-
Keyboard, mouse, usb sound card and Ethernet fully operational using the 7-port USB hub. root@pisces:~# lsusb

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.

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.
- git checkout iw0hdv
Removed all traces of -msse, -msse3 and -ffast-math from Makefile.am and Makefile.in where appropriate in the subdirectories.
- autoreconf -i
- ./configure CFLAGS='-O3 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard' CXXFLAGS='-O3 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard'
- 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.
