[Efi332] BDM troubles

[Paul Helmuth]

I'm (reasonably) sure everyone that has done anything with the Phytec 
development board has used the JTAG/BDM port.

Since you are using GDB, I assume that you are using the GCC tool chain. 
Since you are using that, I also assume that you are using the external BDM 
port. This means you have some BDM port interface (like a Wiggler).

So - you need to make sure that all of your pin-outs match between your BDM 
interface and the Phytec BDM port. As an example, two of the pins are 
reversed between the Phytec port and my Macraigor Wiggler. I have a note on 
James' 555 web page about that switch. Also, you need to follow Phytec's 
bulletin on setting the development board jumpers for using the external BDM 
port.

Other than that, everything should work - but I haven't used these tools 
with Linux.
