Serial AVR JTAG -L and AVR Studio 4.0 - Help Needed Please

Development Boards MicroMod
1

Hardware I am using:

ATMega128: Link - ([ATMega128)

AVR JTAG -L: Link - [AVR JTAG -L

Software:

AVR Studio 4.0 with all the SPs and whatnot.

I am having trouble getting these things to work together. The light on the JTAG turns on when powered up, but then when I try to connect to it, the LED either starts to faintly blink or turns off completely. It eventually gives me the message “Cannont Connect”.

THe platform I set it to is AVR JTAG ICE and I set the device to ATMega 128. I have tried to have it automatically find the com or set it to com 1 and some of the other ports. When connecting to a different board (A motorolla 68HCS) with a different debugger it works fine on COM1 with a serial connect

I really need to get this working as soon as possible since I have a project that really needs to get started. Please if anyone could help I would greatly appreciate it.](http://www.sparkfun.com/commerce/product_info.php?products_id=11)](http://www.sparkfun.com/commerce/product_info.php?products_id=37)

For thos who care or have been reading this. It turns out the voltage regulator on the board was not giving me the correct voltage.

The board needed 5.0V but the voltage regulator was only giving 3.3.

I found this out by connecting a good old fashion power supply to the VCC and GND pins and ran some code through the jtag-l and software and it worked fine.
