I am not building the USRP2 FPGA, or have experience with ISE 12, but the errors you have are all related to BRAM feeding the aeMB CPU - more specifically RAM output -> Mux -> Adder -> FF, mostly with 7 to 10 layers of logic inbetween. Good luck debugging that portion of the CPU. Hopefully you can achieve timing closure.

The plot.py file in gnuradio.wxgui is something ported over to use within GNU Radio for the internals of the graphical flow graph instruments--it's not really something intended for general use. You could see how it's used by our scripts and do that yourself if you wanted, though.

[Discuss-gnuradio] UHD issues on Mac
Hi,
I'm currently trying the UHD driver on my macbook pro, with still very limited
success. I have the newest git version of uhd and gr-uhd, checked out today.
$ uhd_find_devices
--
-- UHD Device 0
--
name: USRP2
addr: 192.168.10.2
which is good, but actually using a simple_source crashes in interesting ways.
When calling
u = uhd.simple_source("addr=192.168.10.2, recv_buff_size=3.5e6",
uhd.io_type_t.COMPLEX_FLOAT32)
or
u = uhd.simple_source("addr=192.168.10.2", uhd.io_type_t.COMPLEX_FLOAT32)
I get the following:
> terminate called after throwing an instance of 'std::runtime_error'
> what(): No devices found for ->
> addr: 192.168.10.2
> recv_buff_size: 3.5e6 ## nothing here with second version
>

The attached log file is crash-all.log.
Just calling
u = uhd.simple_source("", uhd.io_type_t.COMPLEX_FLOAT32)
Gives:
> terminate called after throwing an instance of 'std::runtime_error'
> what(): usrp2 no control response
> Abort trap
with log file in crash-none.log.
After each of the crashes, the uhd_find_devices still finds my USRP2, so the
firmware/FPGA is still running strong. Pinging 192.168.10.2 results in request
timeouts for icmp_seq. The firewall is turned off.
Am I getting it wrong here, how should the driver be used? Or are there some
Mac-specific issues?
Thanks,
