Hello Gabriel,

there are many possible reasons why it wouldn't work, but in my experience 
it is most likely an issue with your SD card.

- Did you put both the firmware and the FPGA bitstream on the SD card? Do 
they have matching versions?

       Yes, fpga u2_rev3-20100603.bin firmware 
txrx_wbx_raw_eth_20100608.bin.  This works but if I replace the 
u2_rev3-20100603.bin by my         u2_rev3.bin, nothing work.

- What SD card are you using? SDHC cards do not work, and the USRP2 seems to 
like 2GB cards (only?). When in doubt, use the SD card provided with the 
USRP2.

   SD card only since the USRP2 doesn't support SDHC (I used the one that 
came with the USRP2)

- Did you write the images directly to the beginning of the card without 
filesystem. You have to use /dev/sdX or the likes instead of 
/dev/sdX{1,2,3,4,...}. There are also graphical tools to flash the card 
somewhere.

    I use u2_flash_tool.py that I found on the web site gnuradio.org. The 
exact code line is
   u2_flash_tool.py --dev=/dev/sdb -t fpga 
/path/to/my/bin/file/u2_rev3.bin -w for the FPGA code
   and
   u2_flash_tool.py --dev=/dev/sdb -t s/w 
/path/to/my/bin/file/txrx_wbx_raw_eth_20100608.bin -w for the firmware code. 
(I used a WBX daughter     board)
   Can you provide me the graphical tools to flash my SD card ?


There is also some info here if you haven't found it yet:
http://gnuradio.org/redmine/wiki/1/USRP2UserFAQ

The second LED lights up when the firmware has successfully initialized the 
lowest level the device (before the ethernet handlers), so without it you 
will definitely not be able to find the USRP2. The first one just shows that 
it is powered up.
