Hi Harald,

How about doing some research before posting such rubbish?

The Nut/OS API clearly states, that "r+" updates an existing file.
http://www.ethernut.de/api/group__xg_crt_stdio.html

Thus, changing

         case '+':
             mflags &= ~(_O_RDONLY | _O_WRONLY);
             mflags |= _O_RDWR | _O_CREAT | _O_TRUNC;
             break;

to

         case '+':
             mflags &= ~(_O_RDONLY | _O_WRONLY);
             mflags |= _O_RDWR;
             break;

as it had been before CVS file rev-1.2 should fix it.
