You might consider "remoting" using something like an Odroid XU4, which
has a fair amount of compute capacity, and supports USB 3, and has a
1GiGe port.

I'd like to to be able to load the firmware over this link too.  Recompiling the firmware to not use USB 2 looks like the most promising path right now, I just still am not quite fully sure how to do that and if it will work.

I am told by Icron tech support that because the B210 seems to first enumerate as a USB 2.0 device, it will not work.  They say that the USB2.0/1.1 data channels are not connected on the Spectra 3022.  Is there any way to make the B210 enumerate as only a USB 3.0 device?  Looking at the B200 FX3 firmware, it looks like there is a config flag for disable_usb2.  Would this do what I need?  How do I build with this flag?  Any help is much appreciated.

Preface: all this talks about uhd+gnuradio, uhd itself has far more slim
deps.

Last I used PyBOMBs (grcon last year) it didn't work too well on C6.
Things
may have changed.
I know it was pushed pretty hard at grcon. I have gotten GR installed
thanks to Ben Hilbern's back port[1 [1]], but always built uhd 3.9 for
the
Cent6/7 installs.

At a minimum I think you'll need newer python + a few modules, newer
gcc(or
clang/icc?), C++11 is only partially implemented on C6 stock gcc, not
sure
if uhd requires it (yet), possibly boost, though 1.48 might work.

CentOS 7 I think I still had to source build some deps, but I might be
mistaken. Either way it will be a much better experience getting it
going.

I believe Ubuntu 16.04 LTS is the most tested. If your security folks or
whatever are willing that would probably be the best experience.

You could try to follow the building steps in Ben's blog for uhd, (sub
in
same cmake arguments) and if it doesn't work, try Cent 7, or if RHEL
isn't
a hard requirement, just install latest LTS Ubuntu.

Note: We lock down the requirements per release, which means any 3.10.*
release will have the same requirements.

I think that CentOS 6.5 doesnt' meet all the requirements (maybe Boost
is too old or something), but I'm pretty sure that people have built UHD
on older CentOSes. Which Python version do you have? Maybe you can use
PyBOMBS which'll automate building everything from source.

Dear Martin,

So, CIC's status is a binary one. For example if the ratio is 3, 3%4 = 3
and because there is a remainder, the CIC is enabled. If the ratio is
20,
both half-bands will be enabled and CIC is disabled as 20%4 = 0. Did I
understand correctly?

Regards,
Altug

Hello Altug,

The CIC can be programed to decimate by a range of integer amounts. If
the
ratio is 20 (50 MHz sampling rate, 2.5 MHz output rate) then both half
bands will be used (divide by 2*2) and the CIC will decimate by 5. Odd
CIC
rates have poor filter roll off compared to even rates.

Hello all,

The release candidate of UHD version 3.10.2.0 has been tagged and is
available for testing. There have been no API breaking changes necessary
since the last release but a small ABI change means we are incrementing
the
ABI number. Updated FPGA and firmware images have been uploaded.

The tag for this release:
https://github.com/EttusResearch/uhd/releases/tag/003_010_002_000_rc1

There have been 83 commits since the last release which can be viewed
here:
https://github.com/EttusResearch/uhd/compare/release_003_010_001_001...003_010_002_000_rc1

## 003.010.002.000

* multi_usrp: Fixed get_normalized_tx_gain.
* E300: Fix for streamer recreation issue. Reduced minimum timeout,
fixed
potential race condition.
* X300: Fix for network discovery, will now return early when correct
serial is found. Fixed issue with DAC sync. All async messages now go
through single DMA channel on PCIe. Improved TX performance. Fixed page
size acquisition for PCIe. Fixed some FW communication errors. Improved
flow control. Removed MTU throttling. Legacy compat falls back to min
spp
for mixed transport types.
* CBX: Fixed LO LPF behaviour in 1.5-2 GHz range.
* UBX: Fixed dtor SIGABRT issue. Better error handling for various
dboard
clock rates.
* TwinRX: Added LO reimport feature.
* GPSDO: Improved detection. Improved query_gpsdo sensor.
* RFNoC: Fixed issue with DDC and DUC command tick rate.
* UHD: Fixed potential memory leak in tasks. Fixed
get_normalized_tx_gain(). Fixed default socket buffer size to honor MTU.
* Examples: Added channel param to samps to/from file. sync_to_gps exits
instead of uncaught throw. latency_test improved output. Use next_pps in
test_clock_synch. Added TwinRX FHSS example.
* Utils: Modified behaviour of uhd_images_downloader so it won't delete
dirs when using -i
* Tools: Updates to CHDR dissector. Added set_time_source_out(). Fixed
LO
API.
* C API: Fixed some missing fields in USRP info.
* Docs: Many minor fixes. Fixed Doxygen warnings related to /* in files.
* CMake: Fixed GCC 4.4 compilation issue. Added ability to specify
package
names.

Best regards,
Derek

 Hi,

Is there any example codes or reference on how to configure the B210 to
TDD mode? Thanks.
