FLASH_erase

FLASH_erase Erases specified segment of Flash memory

Function

void FLASH_erase(

 

Uint32 locator,

 

Uint32 length

 

);

 

Arguments

locator

Addressing and page information for location in Flash

 

 

memory.

 

 

C6711 DSK

 

 

- FLASH_START_ADDR

 

 

- FLASH_PAGE_ADDR(x) :(x)– page number

 

 

- 32-bit Flash address

 

length

Length in bytes of data to be erased. This is limited by

 

 

the size of the Flash memory.

 

 

C6711 DSK

 

 

- length in bytes

 

 

- FLASH_ERASE_ALL – erase entire FLASH

Return Value

none

 

Description

Erases the specified segment of 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 )

 

Note: On 5x boards, 16-bit addressing is used and page information is

 

included in the upper half-word of the address argument.

Example

To erase page # 0 and # 1 in the Flash:

 

FLASH_erase(FLASH_PAGE_ADDR(0), FLASH_PAGE_SIZE*2);

To erase the entire FLASH:

FLASH_erase(0, FLASH_ERASE_ALL);

Note: When erasing the entire Flash memory, the locator argument becomes a dummy parameter.
