Today I updated gnuradio to current svn9988. And while doing that I also
downloaded the binary package of mb-gcc and built the firmware- files,
successfully thanks to the wiki and a well known search- engine.
The new firmware was loaded onto the sd- card successfully(?) is there
supposed to be some output from u2_flash_tool, I can't locate the source
for it, so I can't check for myself. But since I could run find_usrps
with the (probably) new firmware, I guess it went fine.
I then tried all the test- programs, and they ran fine (find_usrps,
tx_sample, ... from usrp2/host/apps/), before lunch, but when I got back
from lunch they didn't.
I simply can't transmit according to my hardware oscilloscope. Although
I see packages flowing on my eth0- device (using wireshark).
And when I try rx_streaming_samples (with a signal- generator as source,
generating a 100kHz sine) I suddenly receive a lot of noise. Looking at
the fft of the received signal one could say that it _might_ be a
sinusoid in there, but very weak. But only after lunch, before lunch the
received signal was a noise free sinus of 100kHz...
The only thing that is working as expected after I got back is
find_usrps. I think I'll never eat lunch again ;)
I'm out of ideas of how to solve this. Suggestions of things to try
and/or check for, no matter how simple would be appreciated.
