Using the Service
The first step is to find the address of the open service method
the ROM Entry Service.
1. Allocate one instance of
2. Initialize the
3. Configure the DataFlash structure with its correct features and link it to the device
4. Now the different methods can be used. Following is an example of a Page Read of 528
// Allocate the service and a device structure.
AT91S_SvcDataFlash svcDataFlash;
AT91S_Dataflash Device; // member of AT91S_SvcDataFlash service
Then initialize the
function:
// Initialize service
pAT91->OpenSvcDataFlash (AT91C_BASE_PMC, &svcDataFlash);
// Initialize the SPI Interrupt
at91_irq_open ( AT91C_BASE_AIC,AT91C_ID_SPI,3,
,AT91F_spi_asm_handler);
// Example with an ATMEL AT45DB321B DataFlash
Device.pages_number = 8192;
Device.pages_size = 528;
Device.page_offset = 10;
Device.byte_mask = 0x300;
// Link to the service structure
svcDataFlash.pDevice = &Device;
// Result of the read operation in RxBufferDataFlash
unsigned char RxBufferDataFlash[528];
svcDataFlash.PageRead(&svcDataFlash,
