Hi all,

I'm trying to flash my first program, (the initialload.c example code).

It compiled fine, but, when I get to the flashing step, I get:

C:\Documents and Settings\Mbobak\My     Documents\Downloads\NerdKits\Nerdkit_Code\Co
de\initialload>make
avrdude -c avr109 -p m168 -b 115200 -P COM5 -U flash:w:initialload.hex:a

Connecting to programmer: .
Found programmer: Id = "  ""; type =
Software Version =  . ; Hardware Version =  .
avrdude: error: buffered memory access not supported. Maybe it isn't
a butterfly/AVR109 but a AVR910 device?
make: *** [initialload-upload] Error 1

Anyone have an idea what my problem may be?

Thanks,

-Mark

Sure the MCU is set to programming mode? And the COM port is the right one? :)

Hi mbobak,

met_fredrik is exactly right. The error you are getting is a pretty generic error that pretty much means your computer can't talk to your MCU. Make sure all the wires are nice and snug, make sure your battery connections are right, and make sure you are in programming mode.

If you still can't it to work post some good close up pictures, we might be able to help you find the issue.

Hi Guys,

Thanks for your reply. Yes, double checked, I'm on COM5. And the programming mode, that's with the switch 'up', that is, closed on pins 24 and 25, correct?

At this point, I think I'm going to strip it down and recheck all the wiring.

Also, I think the project for tomorrow is going to be to build a mounting board, so I can mount my breadboard, battery, and LCD, so that they are in a fixed position relative to each other. Right now, seems I'm stumbling and pulling wires when reaching for other wires, and I've got a bit of a tangled mess on my hands.

Making progress!

avrdude done.  Thank you.

Yay!

Of course, now I switch program mode off, and power cycled the system, and I get nothing....so, I'm sure it's just a loose connection somewhere. I'll be better off when I get this stuff mounted.

FYI, my bonehead move that was causing my problem? At some point, the battery power became detached, when I plugged it back in, I plugged it in on the right side instead of the left. As soon as I moved it to the left, I was in business!

Thanks for the help, I'm sure I'll have many more questions as I progress.
