Custom External Quad SPI Loader

Actually lessons code have a test harness. I implemented this section to my project like this;

 	uint8_t buffer_test[MEMORY_SECTOR_SIZE];
 uint32_t var = 0;
 
 	CSP_QUADSPI_Init();
 
 	for (var = 0; var < MEMORY_SECTOR_SIZE; var++) {
 		buffer_test[var] = (var & 0xff);
 	}
 
 	for (var = 0; var < SECTORS_COUNT; var++) {
 
 		if (CSP_QSPI_EraseSector(var * MEMORY_SECTOR_SIZE,
 				(var + 1) * MEMORY_SECTOR_SIZE - 1) != HAL_OK) {
 
 			while (1)
 				; //breakpoint - error detected
 		}
 
 		if (CSP_QSPI_WriteMemory(buffer_test, var * MEMORY_SECTOR_SIZE,
 				sizeof(buffer_test)) != HAL_OK) {
 
 			while (1)
 				; //breakpoint - error detected
 		}
 
 	}
 
 	if (CSP_QSPI_EnableMemoryMappedMode() != HAL_OK) {
 
 		while (1)
 			; //breakpoint - error detected
 	}
 
 	for (var = 0; var < SECTORS_COUNT; var++) {
 		if (memcmp(buffer_test,
 				(uint8_t*) (0x90000000 + var * MEMORY_SECTOR_SIZE),
 				MEMORY_SECTOR_SIZE) != HAL_OK) {
 			while (1)
 				; //breakpoint - error detected - otherwise QSPI works properly
 		}
 	}

When I debug code with this, code stopped to last "while". My quad spi configuration like this;

Thanks for reply.
