Interfacing jtagulator to mega2560

Hello,

I want to learn about interfacing to a mega2560 via jtagulator. Ive connected to the jtag ports (A7-A4) and also ground. Ive set the jtagulator into OCD mode and established the conection

Interfacing with telnet also seems to work, but when I just try to halt the system it doesn`t work

Fuses for OCD and jtag are set

Anyone got a clue?

Regards Eddie
