AVR Flashforth ATmega 168p only, error: Overlap in .cseg: addr=0x1c01 conflicts with 0x1000:0x1c24

Hi All,

I'm attempting to build flash forth 5.0, daily for the ATmega 168 p. Get's a fury of errors.

Assembly failed, 18 errors, 7 warnings

The other chips seem to build Ok. Ideas?

Thanks,

Try changing KERNEL_SIZE from 0x0c00 to 0x0c80
on line 356 in ff-atmega.asm

I forgot to check that for 16 Kbyte chips the last time I reorganized the kernel.

That's the ticket! Compiled perfectly.
