Hi guys,

what is the state of ATmega2561 & Nut/OS ?

I noticed that extended PC byte was added to AVR context switching . 
In NutThreadCreate(), this byte was originally seeded from fn 
address, but now it is zeroized. This limits thread functions to 
start only in lower 128kB of flash.

Can they then call functions in upper 128kB ?
