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

[Angel - Arrakis]

Hello Joel

I have made a particular implementation of ethernut:
    - I made 3 groups: CRT, NET & OS, with the information of the same 
directories
    - I compile this whith gnu, optimisation level 1, code ARM (not Thumb)
    - After include all this in my code, the sizes ocupied was:
        CRT: 6368 bytes
        OS: 9992 bytes
        NET: 19720bytes
    I don't know if all the modules of the libraries are included, but at 
least the aplication use almost all the facilities
of ethernut, so I suppose that the difference will be small

Hope thas this help you
