E110 problem executing simple code

GNU Radio

Hi list,

when I try to execute a simple code in my new USRP E110, it gives me the
following error:

uhd_sink = uhd.usrp_sink(device_addr = “serial=MY_USRP_SERIAL”,
stream_args=uhd.stream_args(‘fc32’))
File “/usr/lib/python2.6/site-packages/gnuradio/uhd/init.py”, line
116, in constructor_interceptor
return old_constructor(*args)
File “/usr/lib/python2.6/site-packages/gnuradio/uhd/uhd_swig.py”, line
2654, in usrp_sink
return _uhd_swig.usrp_sink(*args)
RuntimeError: RuntimeError: fifo ctrl timed out looking for acks

Besides that, if I dont force a device address, the E110 utilizes a N210
USRP in the same network.

Any suggestions ?

Have you run opkg update; opkg upgrade?

What happens if you try this with the network dos connected? (So it
doesn’t see the N210)

Hi,

I executed am opkg update; opkg upgrade. Now all is working (a LOT of
packages were update).

I had updated all two days ago, probably some problem happened and I did
not
notice.

Thanks.
