[En-Nut-Discussion] Nut/Net ARM port

[Henrik Maier]

William,

what is your experience with the memory configuration? Would you think 
the 256 Kbyte Flash and a 64 Kbyte SRAM of the AT91SAM7X256 is 
sufficient for an ARM Nut/OS?

Compared to the AVR I would expect that ARM version requires much more 
resources.

Cheers
