Re: IO over KVM Switch

My problem vanished when I switched over to Raspbian. Earlier I was using the debian that was the official distro before Raspbian.

Raspberry Pi Reboots on inserting a USB device.

My Raspberry Pi Reboots on plugging in some USB devices. I do not think it is a power supply problem - I am using a 5v 30A power supply (ATX SMPS) and I have see it occur across two OS releases - (debian & Raspbian). The devices I have used are EDiMAX WiFi dongle and RTL2832 USB dongle. What might b...

Re: GNURadio on Raspberry Pi

I finally got it to compile. It might be that the lack of memory was causing problems along with other things. Increasing the swap space helped.

https://www.dropbox.com/s/nll0qhm4z09vv ... RPi.tar.gz is the built binary. Should anyone want to try these, let me know if it works.

Re: GNURadio on Raspberry Pi

A little bit of search got me a patch - http://lists.gnu.org/archive/html/patch ... 65EP52.txt
However, while applying this patch, I discover that it has already been applied to the git repository. So that is another dead end :-(

Re: backpowering the Pi

I am surprised this is working for you. I have a D-Link hub and it will shut off powers to the ports unless there is a host connected. This would not have worked with the hub I have. I do not think this will work. Try checking the continuity of the power and ground between the ports and between the ...

Re: GNURadio on Raspberry Pi

Not much is discussed in the FAQ or docs about library not found. And I had installed all libraries that had libfftw prefix. Nothing had worked.

After installing fftw*, the buildscript managed to proceed. A flaw in the script I suppose.
