[En-Nut-Discussion] Ethernut 3.9.9 - error on build

[William Basser]

If the EEPROM base address is moved from 0 in the config file, an error is
generated in file

Nut/os/confoos.c, line 76.  the code exceprt is shown below.   It complains
that the second argument in eeprom_read_block is not properly cast.

 

I added the specific cast, int* to the function and got a clean build.

 

ASIS:

 

int NutLoadConfig(void)

{

#if !defined(__linux__) && !defined(__APPLE__) && !defined(__CYGWIN__) &&
!defined(__arm__)

    eeprom_read_block(&confos, (CONFOS_EE_OFFSET), sizeof(CONFOS));

    if (confos.size != sizeof(CONFOS) || confos.magic[0] != 'O' ||
confos.magic[1] != 'S') {

        return -1;

    }

#endif

    return 0;

}

 

MOD:

int NutLoadConfig(void)

{

#if !defined(__linux__) && !defined(__APPLE__) && !defined(__CYGWIN__) &&
!defined(__arm__)

    eeprom_read_block(&confos, ((int*)CONFOS_EE_OFFSET), sizeof(CONFOS));

    if (confos.size != sizeof(CONFOS) || confos.magic[0] != 'O' ||
confos.magic[1] != 'S') {

        return -1;

    }

#endif

    return 0;

}
