Re: [Amforth-devel] Help getting started with a atmeg644PA

[Leon N M. <leo...@gm...>]

I've used pd2amforth to generate the files, and I switched to a different usart 
file. That got rid of one error, but I still have the other one:

devices/atmega644pa/device.asm(13): error: Overlap in .cseg: addr=0x1 conflicts 
with 0x0:0x2

Any other advice?

Thanks.
