Is the BDI1000/2000 the least expensive way to use the JTAG/COP?

OK, now you can program your boot device. You plug it in, power on, and you are lucky: no magic smoke to be seen. But your code doesn't run (and I guarantee you that it will not run on first attempt). I bet you'd like to have a debugger then... > Or: Leave the EEPROM on RCS0 all the time.

Yes, two: find some working hardware which already has the firmware running, or get yourself the neccesary tools.
