Hi, Daniel,

I think that you first must entry to the bootloader. I dont know where
the enter point but you may load nut\bin\basemon.hex back to board by JTAG
ICE and try  to enter to bootloader pressing "J" . If enter than
bootloader alive :) .

DK> Hi,

DK> I'm quite new and just bought the ethernut starter kit with ethernut 2.1. Everything is working just fine. I used the 'J' option and downloaded a .bin file from my tftp in the basemon program.
DK> Now the nut start this new app after every reboot. I guess the bootloader is still left in the memory but the processor start on "wrong" address. I read something about changing fuse-bits. Can
DK> someone please explain how to do this in an easy and reliable way using the JTAG connection. I use the newest WinAVR and also downloaded the AVR studio.

DK> Thanks!
