Hi Michael, To get GNUradio to build correctly from source on the RPi2 you need to do a couple of things:
1. Increase the swap space on the device 2. Build single threaded (make -j 1) 3. Make a source fix in one of the volk ARM asm files. Did you run into this error when you tried your build ? BTW the RPi2 is able to handle the 2.4Msps sample rate of an RTL-SDR dongle. And about the same rate for the sdrplay and airspy. It does not handle higher sample rates supported by B200mini etc. --Patrick Date: Wed, 24 Feb 2016 15:26:40 -0500 From: mskag...@umbc.edu To: discuss-gnuradio@gnu.org Subject: [Discuss-gnuradio] B200mini and Raspberry Pi 2 Connectivity Hello all, After sorting out my power issues with the B200mini (it required a dual USB to 3.0 mini cable, due to browning out the single USB 3.0 connection), I'm now trying to connect my B200mini to a Raspberry Pi 2. I was excited when I found that Raspbian has a gnuradio and gnuradio-dev package available, but that excitement quickly faded when I found that it was GNURadio version 3.7.5 and UHD version 3.007.003. I'm not sure if the GNURadio version is an issue, but I know that UHD 3.007.003 is far too old to recognize the B200mini (I tried multiple times before realizing my problem). The GNURadio package on Raspbian works like a charm, but cannot detect the B200mini due to UHD. I have installed UHD from source on the RPi2, and successfully probed the B200mini, but could not get GNURadio to compile from source correctly. If I install a newer version of UHD after installing the gnuradio and gnuradio-dev packages, I get the "uhd_find_devices: undefined symbol" error. I'm trying to find a middle ground. My question is, is there a way that I can update the Raspbian package of UHD that it could both detect the B200mini and I can use GNURadio Companion?
