[En-Nut-Discussion] AVRStudio & JTAG Programmer from ethernut 2.1b dev kit

[amit khandelwal]

Hello Ernst,
    I guess you need to program you JTAG. there must be an upgrade.ebn
file if I remember correctly in the Atmel directory of your
installation on windows. Just write that file on to the jtag device
and you should be able to use JTAG.
