Insert the SD card into the card reader, and the card reader into a
USB port on your computer
Run “sudo u2_flash_tool --dev=/dev/XXXX -t s/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
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.
