too many initializers for struct

Question

I'm currently working on a EEprom file structure which is filled with default values while compiling. All works fine so far except for one structure and i can't seem to find the error..

typedef struct { // ===== instance parameters =====
        BOOL bInstanceActive; 
        BYTE nInstanceGrp[4];
        BYTE nEventFilter;
        BYTE nEventScheme;
        BYTE nEventPriority;
        BYTE nShortMul;
        BYTE nDoubleMul;
        BYTE nRepeatMul;
        BYTE nStuckMul;
        BYTE nDummy[3];
    } InstanceBlock;
#define DEFAULT_INSTANCE_BLOCK  {1, {255,255,255,255}, 244, 0, 2, 15, 5, 10, 30, {0}}

The Types "BOOL" and "BYTE" are both unsigned char.

the different structs are then combined to one EEprom_Mapping struct (but i currently only have this one in it, all others work fine):

typedef struct {
    InstanceBlock xInstance[1];    ** edited should be 1 instead of 0
    } EEprom_Mapping;
#define DEFAULT_EEprom_Mapping { DEFAULT_INSTANCE_BLOCK }

It is then initialized this way:

EEprom_Mapping xEE __attribute__((section(".eeprom"))) = DEFAULT_EEprom_Mapping;

The error message is "too many initializers for 'InstanceBlock [0]'"

Thanks in advance for any help.

Answer 1

For your second hidden question, with 4 elements, you miss some brackets:

// Note double brackets
#define DEFAULT_EEprom_Mapping  {{ DEFAULT_INSTANCE_BLOCK, DEFAULT_INSTANCE_BLOCK, DEFAULT_INSTANCE_BLOCK, DEFAULT_INSTANCE_BLOCK }}

Demo

Indeed, xInstance is an array inside a structure, so you need brackets for initializer list of structure and brackets for initializer list of array.
