I bought this little board here for 20 bucks
I have an ATMEL AVR JTAG ICEMKII
First , has anyone used these boards? with the JTAG interface?
Please correct anything I have wrong here before I connect it up.
Picture shows layout of JTAG ICE 10 pin connector, On the right is the 10 pin connector I will make. My understanding is I power the ET-AVR-STAMP with a regulated 5V supply and I power up the JTAG ICE with its 9V supply. What I don't know is what pin 7 VSupply and nTRST and nSRST are for on the JTAG ICE. SHould I just leave them unconnected as I show in the diagram?
Do I understand correctly that the JTAG ICE will be able to download programs using AVR studio, set fuses, and step thru code that will execute on the attached mega128 chip.
Are there fuses I can set that will make the board not respond that I would have to use something other than the JTAG ICE interface to reset? (like the ISP programming setting a fuse wrong and having to use high voltage programming) what i am asking, is the jtag ICE similar to high voltage programming?
