Re: [Discuss-gnuradio] Trying to find a stable copy of the FPGA code for the USRP2

[Matthias Wilhelm]

Hello, 

you can find the newest code (for the UHD driver) here:
http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki

You can also find a tool with graphical user interface in host/utils to flash 
the card.

The link
git.ettus.com/ettus/fpga.git
should be correct with the "raw ethernet" host driver, but I think it is 
included in the UHD repo above as well, so the UHD repository is recommended.

LED "D" indicates that the firmware is up and running, if it does not light up 
it means that (i) the FPGA is not set up or (ii) that the firmware is not 
running.

The problem is probably an error on the SD card. Several issues come to mind 
here:
- both firmware and FPGA bitstream must be flashed on the card. That is, 
txrx.bin and u2_rev3.bin. You have to use the flash tool twice.
- SDHC card are not supported, they must be SD.
- you must flash directly to the beginning of the card, so use /dev/sdX instead 
of /dev/sdX{1,2,3,4,...}. This nukes the filesystem and (possibly) the master 
boot record, so you cannot have other data on the SD card, and old data will 
disappear.
- mismatch between FPGA and firmware version (but this leads mostly to strange 
behavior)

I have posted more info some weeks ago, and there is a wiki page with more info:
