Hi Marc!

Have a look at http://www.ethernut.de/en/portarm/gbaxport2.html

Maybe you can use this information as a kind of template for your port.

Good luck

Betreff: [En-Nut-Discussion] NutOS on AVR Hardware < 128K flash

Hi alltogether,

I'm checking the possibility to use NutOs on an ATMega64/32/8

I tried to compile it with a hardcoded MCU-Setting, after I used the
STK501 setting with an ATMega103.

First problem is that these little flash cpus do not have the RAMPZ
register. My first approach was to include some #ifdefs
in the relevant files, but there seems to be more to do, because next
thing is, that uart1 is missing and so on.

Is there a generic approach on how I could get on with this task - some
kind of minimal hardware setting I could base my work on?
And after getting the minimal hardware running add one working driver
after another?
