I have to qualify my expertise by saying I'm a new Mac user. I am successfully programming OpenEVSE within the Arduino IDE which runs the avrdude command. Here is a copy and paste from the log when the Arduino environment runs avrdude successfully programming my kit.
avrdude -C/Applications/Arduino.app/Contents/Java/hardware/tools/avr/etc/avrdude.conf -v -patmega328p -cusbasp -Pusb -Uflash:w:/var/folders/l8/3xv3gg314szdq1zq0qhwgp200000gn/T/build4057303063183718273.tmp/open_evse.cpp.hex:i
I hope that helps a bit.
Thanks - I don't have the same setup with an Arduino IDE on my Mac, but maybe I'll try some of those parameters/arguments you are using.
it seems like my installation of AVRDude is old and just doesn't include the m328p profile. But I'm having a heck of a time finding the updated version for a Mac.
I'm not sure it this will help or not. You can install the Arduino IDE for free. It includes Avrdude. I just poked around my Mac and found the path is
Keep in mind I'm new to Mac, but I'm an old-school-UNIX-fart so I feel comfortable poking around with the Mac Terminal tool.
I imagine you could install Arduino. Then open from the Launchpad the Terminal tool. Then cd /Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin Then you can run avrdude from there from the command line. You can type ./avrdude -help when you get to that directory. To run avrdude from the command line when you are in that directory you can put ./ in front of it since that directory is not in your command path. ./ says "look right here" instead of looking elsewhere in the command path.
I'm sorry my advice is not totally turn-key simple. I'm new to Mac but liking it a lot so far.
Let me know if I can offer more advice,
Are you still having problems with avrdude on mac? I use Mac for all my openEVSE development, have tried different ID platforms and use avrdude without any problems. If you are still having problems, I will investigate it further and help solving it with you
When I am done the device still shows as being on 3.1 firmware....what am I missing.

avrdude done. Thank you.
I looked at your bat file and adapted the commands I missed.

Now it says it is 4.8.0.
>>>I received a question from a Mac User, Does anyone know the answer to John's Question?
I have a Mac, so I can't follow the Windows instructions exactly, though I tried to use the commands in the flash.bat file:
avrdude -c USBasp -p m328p -U flash:w:open_evse-390.hex
I got this error below. Is there another part number that I can use?
