    YEP.

    To use JTAG you must use the USB blaster rev B. There are some problems when you are using the rev A.

    If you are using a custom board, pay a real attention on the JTAG connection : pullups, wire size.

    To make my JTAG working I had to change pullups from 10KR to 1KR and add a 32R serial on the JTAG clock.

    I use the ByteBlaster II (LPT) and it seems to work fine most of the time (download, debug...). For more information you really should read the errata.txt.
