AVR-Chat

Okay, I soldered in the 40 pin socket and plugged an ATmega32 in it.  I did
the firmware upgrade (communication between the PC and the AVR Dragon is
just fine).  But when I go to start debugging and select the AVR Dragon and
Target processor ATmega32 I get this error message:

 

"Failed to identify target.  Would you like to retry with external reset
enabled?"

 

I then click on YES and I get the message:

 

"Unable to find supply voltage on target.  Please verify that the AVR Dragon
is correctly attached to target.."

 

The computer is properly communicating with the AVR Dragon is seems.  What's
wrong? :)

Did you install a 20x2 header connector to the board (which provides
the connections to the 40-pin socket)? Did you connect (with jumper
wires) the ISP or JTAG pins from the dragon to that 20x2 pin connector
so that the Dragon is connected with your 40-pin socket?

So can we assume (bad word) that you have the JTAG wiring
correctly done and all 4 power pins connected?

This says a lot, check the JTAG wiring and holler if you need
to find the pin out.

Also remember that you will need to enable the OCDEN fuse by ISP.
The JTAG fuse is normally already checked but you may want to verify
that too.

John,

 

Okay I tried to set the OCDEN fuse by ISP but the board keeps giving the
error:

 

"Setting device parameters: FAILED!"

What about the supply? Can you read the target voltage from the
Board screen of the programmer? It could not be found before.
If you can read the supply the next thing is to set the ISP
frequency to 250KHz (from the same screen) as the Dragon goes
nuts when it does not find a target supply and may revert
to 1 or 8 MHZ.

Thanks John.  Um.  I fixed it.  Apparently, the prototype area, as they all
it, has to be manually hooked into the JTAG, ISP, Parallel and Serial
Programming, and also the DebugWire thing.  I didn't know that.  It's
working great now thanks :)

Congratulations and happy Dragonning :)
Once you get the idea of the prototype area it's not so
bad. You can understand that Atmel could have not wired
up the socket for any particular type of chip. I have a
40 pin ZIF socket on mine but I haven't needed to use it
yet as I have many boards that I can work with different
types of processors.

Kevin,

 

Fixed days ago just like an hour or so after I posted.  But yes, a common
mistake.  I assumed the prototype area was wired in but it wasn't.  I *love*
my AVR Dragon.  I only wish it worked to 64K or better yet ideally for me to
128K.  Worx good.

 

Thanks.

 

Barry

Yeah, I saw that you got it fixed. For some reason, it took 6 days for my
message to go through the list:

My bad.   Hadn't checked pending messages.
