[En-Nut-Discussion] Nut 3 keeps booting from TFTP at reboot

[Jesper Hansen]

Okay I see.
It works fine with just downloading, but is it normal that it takes 
about 10 seconds from entering the  name of the file to load before the 
download starts ?
Same if I just reset the board, it takes 10 seconds or so before it 
requests the file from TFTPD.

Is the code for BootMon available somewhere ?
