[Discuss-gnuradio] X310 firmware questions

[David Miller]

Hi,

I have two questions about X310 firmware, please.

1.
I want to use two 10GigE ports, so need the XGS image. When I download 
this with uhd_images_downloader.py, I get the error that indicates a 
firmware mismatch (Expected FPGA compatibility number 0x4, but got 
0x3.0). I am using the latest live GNURadio DVD based on GNURadio 
v3.7.4.  I think this indicates to me that the XGS firmware downloaded 
is not the latest. Where can I get the latest, or one that is compatible 
with GR 3.7.4 please?

2.
Using the HGS image from the live DVD (GR 3.7.4, it is happy about the 
compatibility, being 0x4) burned onto the X310, the example applications 
mostly seem to work OK, except rx_samples_to_file. When this is run, it 
works fine (with the 1GigE port), except it will only run once when 
using the 10GigE port.  When run again is complains about a recoverable 
error, then won't run thereafter. A power cycle is required, as the X310 
seems to lock up completely and cannot be detected by any of the example 
applications again. I am using an Intel X520 based adaptor as 
recommended in the manual, and a copper passive direct attach SFP+ 
cable. Other example apps such as rx_timed_samples and benchmark_rate 
work fine. I am also using a recent XGE driver as provided with Centos 6.3.

Thanks for any help,
David
