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

This means that the SD card is wrong, the USRP2 cannot boot correctly.

I think it should work with 3.2.2, the problem is the SD card.

What error does it give? 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.
