[En-Nut-Discussion] Error messages while building up Nut/OS

[Helmut Holbach]

Hello,
I get error-messages while building up Nut/OS.
The target cpu is ATMega 2561 on modified Ethernut board 1.3h

Ethernut 4.8.2 GCC  and avr-gcc (WinAVR 20090313) 4.3.2   avr-libc 1.6.6

The message of the Nut/OS configurator:
13:54:34: Loading C:/ethernut-4.8.2/nut/conf/ethernut13h-256gcc.conf
avr-ar: creating libnutarch.a

The extract of the eeprom.h:

static __inline__ void
eeprom_read_block (void *__dst, const void *__src, size_t __n)
{
#if (! (defined(__AVR_ATmega2560__) || defined(__AVR_ATmega2561__)) )
    __eerd_block (__dst, __src, __n, eeprom_read_byte);
#else
    /* If ATmega256x device, do not call function. */
    while (__n--)
    {
        *(char *)__dst++ = eeprom_read_byte(__src++);     // This is 
line 290
    }
#endif
}



Thanks
