Re: update: new FX2 firmware / boosted USB bandwidth

Hi Dominik,

Dominik

This is a great achievement. I tested it with an old 2GHz P4 laptop
(but with good USB controller) and was able to reach about 41MB/sec. The
tests were with/without FPGA HB filter in one direction using your
pre-built images.

USRP1 max transfer of 8 Msps in one direction should be from history
now. I hopes your patches applied to the trunk.

Thank you for sharing it with us.

Best Regards,

Firas

Could you try to set different fusb parameters? I observed that, since
the FX2 is less likely to be a bottleneck, tuning of these parameters
may have greater impact than before. E.g. my laptop did an additional 2
MB/s with B = 16384 and N = 1000 (test_usrp_standard_rx -B 16384 -N 1000
etc.).

Thank you for sharing it with us.
Thanks for the feedback.

Best regards
