Hi,
is there a plan to support the new atmega series 4808,4809 in the AVR compiler ?

I made a quick modification today and it seems doable to add these devices without much change. Compared the code generated for a basic test between modified FPC and avr-gcc with atmega4808 updated from latest update pack and the binaries seem to match quite well. A bit more effort is required to convert the register addresses and bit names from the definition file for the xmega style in the converter I use.
I can share a patch if you want to test the compiler with an actual device or simulator.

That would be nice. I have the chip ( Microchip was so kind to send me
some samples ) so I think that I could do some test after I make a
breakout pcb .
Dimitrios,
I've made a fork of fpc on github so that all the changes can be easily checked out in one go: https://github.com/ccrause/freepascal/tree/avr Note that the changes are in the avr branch.
