If the TFTP server is running on linux, you need to create an empty file in the TFTP root called `badboot.bin` - and give it write permission by running `CHMOD 777 badboot.bin` - this allows the JTAG unit to write to this file. if you are using a windows TFTP server, this shouldn't be necessary.

Now very carefully connect the other end of the power brick to the BDI2000 (the power brick should not be plugged into the wall yet) - plug it into the top set of power pins, matching the red and green stripes. MAKE SURE TO GET THIS RIGHT! See the following picture for the correct way:

Now plug in the power supply to the BDI2000. Be gentle and make sure the key on the plug is facing the correct way - I had to hack up that power supply out of parts as it did not come with one.
