Re: [Flashforth-devel] building flashforth with avra?

[Mikael N. <mik...@fl...>]

Hi Chris, 

Here is the link for the answer I got from Microchip. They modified the
XC8 suite somehow. Maybe both AVR-AS and AVR-LD.

It is possible use a custom linker script instead, but I did not want to
maintain linker files for FlashForth. 

If you come up with the linker scripts for the supported Atmegas, I can
add them into  FlashForth.

Seems like I should be able to get something equivalent to .NRWW directive with some combination of a named section and a section address in a linker script.
