I'm developing a board for an automotive application and desire to use the ATmega32M1. Having not found any Arduino bootloader or accompanying files on the internet for the ATmega32M1, I tried to write my own files for the ATmega32M1, but I seem to be missing something. Therefore I thought I'd ask if there was anyone here who has or knows where I can get the files to run Arduino on an ATmega32M1.
Thank you!
You can try here:

32M1 looks like a nice chip with some interesteing IO variations, comparable memory-size wise to Atmega644P.
Well, I guess more like a '328P:
32KB (16K x 16) FLASH, 1K x 8 EEPROM, 2K x 8 SRAM
Thank you, CrossRoads, for the link. I will check it out and see if I can use the information there.
I find the ATmega32M1 attractive for its CAN capability and it's small size (7mm x 7mm)! I've been using the AT90CAN128 which has been great, but I want this board to fit easily inside some heat-shrink tubing, so the smaller form of the ATmega32M1 is better suited.
Okay, I've tried coping the core folders and files as suggested at avr-developers.com. I then updated the board.txt file, pins_arduino.h, avrdude.conf, etc. for the ATmega32M1.
Now I'm back to the same problem as I had posted earlier: Trying to run Arduino on an ATmega32M1. Compiles, uploads, but doesn't run. - Microcontrollers - Arduino Forum. Arduino IDE recognizes the chip, compiles without error, uploads without error, but then the chip doesn't seem to run the sketch!
Can you connect something like LED's and blink them or is the core locking up?
Riva, thanks for the inquiry. I've tried my own code, but something isn't quite right. I cannot get an LED to blink! That side of the attempt can be found in this thread: http://forum.arduino.cc/index.php?topic=265078.0. That is why I was asking if anyone else out there had the code already written.

As the LED is not blinking that makes me think the core is not correct and either not setting system up correctly on power one or crashing/ locking up.
The site Crossroads linked to does not seem to have a core to support your 32M1 so maybe someone who knows how (not me BTW) will be able to change/write a core. Another option might be to use a different development environment to Arduino and port code/libraries to suit it.
