Hi Enoch, as Ian has mentioned, there is discussion on the avra-u...@lists.sourceforge.net list, too.
avra is currently missing correct handling of "forward references". -> change "jmp_" to "jmp" in amforth.asm to work around that. avra is also not using the parameter "ram_start", which is given in the device information. See the workaround given in http://sourceforge.net/mailarchive/forum.php?thread_name=50684CCD.9070001%40nassur.net&forum_name=avra-user With these in place I was able to produce working .hex files for atmega644p controllers (amforth-4.9). Help to improve avra is certainly welcome. Cheers, Erich On 10/02/2012 10:51 PM, Enoch wrote: > Thanks for your work, Matthias.
