Thread: warning: cast to pointer from integer of different size

Hi

I'm sure this is a simple problem but I'm quite stuck, when ever I compile my code I get the "warning: cast to pointer from integer of different size" warning. Could someone show me how to cast/point or address the variable to stop it, thanks

The WriteUserData function requires a uint8_t data array type to work.

Code:

typedef struct {
  
	uint64_t MacAddress;
	uint64_t RootMacAddress;
	uint16_t PANId;
	uint8_t device_Type;

} PACK configData_t;

Code:

int setConfigData(configData_t *cfg_dta) {

	uint8_t success = 0;

	if (WriteUserData(0, (uint8_t*)cfg_dta->MacAddress, 8, (void*)WriteCallback) != SUCCESS) {
		success = -1;
	} // if

return success;
}
