If my bootloader speed is at 38K that indicates my bootloader is pre 0023r4.

And since INT2 support was introduced in r4 this also explains why my INT2 isn’t working…

Will burn a new bootloader on the chip and try again.

Thanks for your time!

I verified INT2 works a couple days ago, I happen to use INT2 on one of my boards and didn’t have an issue. Using the older bootloader shouldn’t effect INT usage though.

The upload speed lines should read:
atmega644.upload.speed=57600
to
atmega644.upload.speed=38400

My x-tal is 16MHz
In IDE 0023 I used the same settings.
Note: The bootloader on my chip was burned with IDE 0023.
perhaps that is the reason that I had to use modified settings for IDE 1.0.1.

Any info about int2 ?

Also you changing one line from one chip to another, that doesn’t make any sense.

Installed the Arduino 1.0.1 IDE and Sanguino-0101r1 files but had to patch boards.txt before I was able to upload sketches:
Changed
atmega644.upload.protocol=stk500
to
atmega644.upload.protocol=arduino

atmega1284.upload.speed=57600
to
atmega644.upload.speed=38400

Have you tested int2 on this relaese?
Int0 and int1 work just fine, but I can’t get int2 to work.

Suggestions?

As for compiling, I was able to get it to compile after defining thoes macros, TX works but RX doesn’t due to the PCINT stuff being broken.

I had problems compiling SoftwareSerial, I added these lines from mighty-1284p:

#define digitalPinToPCICR(p) (((p) >= 0 && (p) < NUM_DIGITAL_PINS) ? (&PCICR) : ((uint8_t *)0))
#define digitalPinToPCICRbit(p) (((p) <= 7) ? 1 : (((p) <= 15) ? 3 : (((p) <= 23) ? 2 : 0)))
#define digitalPinToPCMSK(p) (((p) <= 7) ? (&PCMSK2) : (((p) <= 13) ? (&PCMSK0) : (((p) <= 21) ? (&PCMSK1) : ((uint8_t *)0))))
#define digitalPinToPCMSKbit(p) ((p) % 8)

But I don't know, if they are correct.
I'm trying to compile http://timewitharduino.blogspot.de/2012/03/wise-clock-4-with-atmega1284.html
but it isn't working yet.

Here I got compiler warnings:
