USRP2 SD Card rewrite

usrp2/firmware/txrx.bin -w”
/dev/XXXX has to be replaced with the device for the SD card
"

This needs some small corrections I think.

The correct instructions seem to be

cd usrp2/firmware
Run “sudo ./u2_flash_tool --dev=/dev/XXXX -t s/w ./apps/txrx.bin -w”

with the rest which I emphasize again. If you get the wrong XXXX for
the device, you can wipe out your hard drive. Most people will have
their hard drive as /dev/sda and on my computer it seems the device
is, like Matt’s computer, to be /dev/sdb.

Surely the kernel would prevent you writing to a disk that is opened by
it for
the FS. (It does in FreeBSD anyway)
