m1284 code fails to write very large files... #57

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

It looks like the value of NRWWSTART is wrong due to byte vs word addressing 
confusion; it should be 0xE000 (like the m1280) rather than 0xF000
(The Atmels docs are word address based, so F000 is really 1E000, and optiboot 
loses the high 1 bit (into rampz) before the comparison)

Confirmed.  (So the size limit with this bug should be 1E000, or 122880 bytes.)
