Texas Instruments TMS320C6000 manual FLASHwrite, To write from writeBuffer to pages 1

Page 47

 

FLASH_write

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);
