More information here: http://gnuradio.org/redmine/wiki/1/USRP2UserFAQ#How-do-I-change-the-firmware-and-FPGA-code-on-the-SD-Card Try the following: (check with the command "dmesg" to to see which device is used for the SD card, it may change every time you insert the card) $ dmesg You will see something like ... sd 0:0:0:0: [sdd] 3842048 512-byte logical blocks: (1.96 GB/1.83 GiB) usb-storage: device scan complete sd 0:0:0:0: [sdd] Write Protect is off sd 0:0:0:0: [sdd] Mode Sense: 03 00 00 00 sd 0:0:0:0: [sdd] Assuming drive cache: write through sd 0:0:0:0: [sdd] Assuming drive cache: write through sdd: sdd1 sd 0:0:0:0: [sdd] Assuming drive cache: write through sd 0:0:0:0: [sdd] Attached SCSI removable disk athe end of the output when you insert the card, so in this example sdd is correct. Be careful that the device is correct. Then do $ sudo u2_flash_tool --dev=/dev/sdd -t fpga u2_rev3-20100603.bin -w $ sudo u2_flash_tool --dev=/dev/sdd -t s/w xrx_wbx_raw_eth_20100608.bin -w > > Then, you should check if the USRP2 boots properly, > > i.e., if LED "F" is constantly on (power) and LED "D" turns on after a > > short while. > > This indicates that the SD card is working and the USRP2 booted > > successfully. > > Before update, LED D and F is. > But after that only F.

Maybe the device has changed from /dev/sdd to something else. You can check with "dmesg". If $ sudo u2_flash_tool --dev=/dev/sdd1 -t s/w xrx_wbx_raw_eth_20100608.bin -w works, then $ sudo u2_flash_tool --dev=/dev/sdd -t s/w xrx_wbx_raw_eth_20100608.bin -w must also work.
