[En-Nut-Discussion] Problems using global variables and/or floating point numbers on Nut/Os (using ethernut 5)

[Vegard Aaker]

Yes,

I am using Ethernut 5 board and nut/os version 4.10.

Do anyone have another os config file for the ethernut 5 board which
utilize the floating point unit on the processor? Even better would be if
anyone has both a code example and a config file I could try :)

Thanks for the help!
