Message-ID:

Content-Type: text/plain; charset="iso-8859-1"

Hi,
??? I am wondering if there is a way to retrieve in realtime A/D loading data 
(i.e. crest factor) for the N210 et.al (so the RX path).?? This would be the 
loading of the 100 Msps A/D, before it goes into to the tuners.? Otherwise, I 
may not be able to tell if my input is overloading the A/D. 
Thanks,
David

You might find this link to code examples for the various options useful:

In a gui, you may want to direct the error messages into a pop up window
of some sort:

Josh:

I am having the same problem as Ken with the "S"s while transmitting from the 
USRP-E110.  I thought I would get your latest FPGA fix a try downloading 
usrp_e100_fpga_v2.bin to /usr/local/share/uhd/images, saving the original E110 
bin file, and renaming it to usrp_e110_fpga.bin. I thought that would be too 
easy to fix the problem and it didn't. I got the following error:

linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500; 
UHD_003.005.001-25-ge134b863
Creating the usrp device with: ...
-- Loading FPGA image: /usr/local/share/uhd/images/usrp_e110_fpga.bin... done = 
1
ERROR: EnvironentError: OSError: INIT_B went high, error occurred.


I am guessing that there are some differences in the FPGA builds between the 
E100 and E110.  Do you have a version with the fixes for the E110???

Hi Josh,

I replaced the file and the problem still remained.  However, it seemed to take 
a bit longer before the sequence errors kicked in.

Thanks,

Subject: [USRP-users] Libertas driver for the W2CBW003
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi,

For our application, we wish to decode 802.11 packets on a consumer 
grade wifi module.  I'm reaching out to anyone who has replaced the 
Gumstix Overo board in the E100-series machine with a wifi-enabled 
Gumstix board, namely the Overo FireSTORM.  I have already replaced the 
board in our machine, but have been unable to get the wifi module to 
work (Everything else seems to work perfectly).

The FireSTORM has the exact same configuration as the packaged Gumstix 
board, but with the addition of a wifi module soldered on. I see no 
reason why reason it shouldn't work, and suspect it is a driver problem.

Namely, in my driver log, I found the following error:

lib80211: common routines for IEEE802.11 drivers
lib80211_crypt: registered algorithm 'NULL'
cfg80211: Calling CRDA to update world regulatory domain
libertas_sdio: Libertas SDIO driver
libertas_sdio: Copyright Pierre Ossman
libertas_sdio: failed to find firmware (-2)
libertas_sdio: probe of mmc1:0001:1 failed with error -2

Has anyone else attempted to do this?  I've tried downloading the 
relevant linux-firmware files and placing them in /lib/firmware, but 
that didn't seem to work (same error).

Regards,

Michael Yan

Correction:  I downloaded the tested your second build:
http://files.ettus.com/binaries/e100-misc/usrp_e100_fpga_v2_timing.bin

not the first one:

http://files.ettus.com/binaries/e100-misc/usrp_e100_fpga_v2.bin

The Overo FireSTORM uses the WI2Wi W2CBW003 - 802.11 b/g +Bluetooth part. using 
the  Marvell 88W8686 SDIO/GSPI chip.  The chip vendor recommends you use their 
WIFI driver and not the libertas_sdio driver supplied with the unit.  I would 
start with sales @ WI2WI:
