I'm trying to program a ATmega328p using the AVR pocket programmer on OSX 10.7.3. The device initializes fine and I can read/write the fuses but reading or writing the flash it won't respond.

Attempting to write:

Code: Select all

avrdude -c usbtiny -p m328p -U flash:w:blink_1MHz.hex -v

Using more verbose output it sends the command "CMD: [4c 00 40 00] [00 4c 00 40]" over and over over...

Any ideas?

Thanks!

Update:

After playing around with it more (while holding back the urge to just throw entire breadboard out the window.) I was able to get it working. Seems the problem is/was the compiled hex. Using the hex file from blink_1MHz.zip or even taking the source code and compiling it myself on my Mac (Using Crosspack: http://www.obdev.at/products/crosspack/index.html) doesn't seem to work. But if I compile it on a separate Linux box and then transfer the .hex onto my Mac, then flash with avrdude everything works as it should. Weird.
