[Discuss-gnuradio] UHD issues on Mac

[Matthias Wilhelm]

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
> 
> Abort trap


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, 
Matthias
