FLASH_write

6-7

FLASH API Module

Description Writes data to the Flash address (locator) from a source address (src).

This function is limited by the page length of the Flash memory.

Note: This function does not affect unspecified segments of Flash. For

example, altering the lower half of a page of Flash memory does not

change the value of the upper half page.

C6711 DSK

- Locator contains 32-bit address of Flash location

-FLASH_START_ADDR is 0x9000000

- Flash address range: 0x90000000 to 0x90020000

- FLASH_PAGE_SIZE = 0x80: 128 bytes

- Page number range: 0 to 1023

-FLASH_PAGE_ADDR(x) = FLASH_START_ADDR +

x*FLASH_PAGE_SIZE )

- If the source address begins in the middle of a page, the write will

invalidate all other data on the page.

Example To write from writeBuffer to pages 1 and 2:

char writeBuffer[FLASH_PAGE_SIZE*2];

FLASH_write((Uint32)writeBuffer,

FLASH_PAGE_ADDR(1),

FLASH_PAGE_SIZE * 2);

1 2 ... 42 43 44 45 46 47 48 49 50 51 52 ... 61 62
