I have compiled and run UHD code that was downloaded one day in last week.
One problem was that "tx_timed_samples.cpp" does not work.
The timing control didn't work.
Even I give 10 secs delay, the code just promptly send samples without any
delay.
Whereas receiver properly wait for the specified ti

Is the FPGA code for mimo cable support available? Is that also on the
packet_router branch (you mention only the host code below)? If not, how
can I access it?
Also, are there example host programs that exercise this code?
Thanks,

I actually need to modify the FPGA source to add functionality to it. Is
the source available?
Thanks.

Hi Martin,
pfb_channelizer_ccf will seperate all channels, But I dont need each
channel.
I only need the channel I am interested in. Seperating all channels will eat
a lot of CPU resource.
I have check pfb_channelizer_ccf source, it finally use fftw to process
channelizer.
So can I directly use fft

Not really. It's a very efficient algorithm
Hi
When I port the firmware and the u2_rev3.bin downloaded from the repository
everything works fine. But when i compile the usrp2 code (successful
compilation) and I port it with my firmware, there is a problem. The
problem is the F led light glows and the D led light does not glow. I am
