Field Documentation

uint32_t(* ROBOOT_FLASH_Operations_T::FlashUnlock)(uint32_t page_address)

Unlocks FLASH memory for subsequent erase (once) and write (many) operations. This function is called ONCE before erasing and writing of the FLASH content for a given page (sector).

Parameters:

page_address

address of FLASH region for requested unlock operation

Returns:

non zero value if unlock operation failed

Referenced by ROBOOT_InitProcessing().

void(* ROBOOT_FLASH_Operations_T::FlashLock)(uint32_t page_address)

Locks FLASH memory after bootloader finished erase and write operations. This function is called ONCE after erasing and writing of the FLASH content is completed for a given page (sector).

Parameters:

page_address

address of FLASH region for requested lock operation

Referenced by ROBOOT_InitProcessing().

uint32_t(* ROBOOT_FLASH_Operations_T::FlashErasePage)(uint32_t page_address)

Erases a FLASH page (sector) at the specified address.

Parameters:

page_address

address of FLASH page (sector) for requested erase operation

Returns:

non zero value if erase operation failed

Referenced by ROBOOT_InitProcessing().

uint32_t(* ROBOOT_FLASH_Operations_T::FlashWriteData)(uint32_t write_addr, const uint8_t *chunk, uint32_t chunk_len)

Writes a supplied buffer content into FLASH at the specified address. This function should check (verify) if written data is equal to requested one.

Parameters:

	write_addr	address of FLASH page for requested write operation
	chunk	content to write
	chunk_len	length (in bytes) of the content requested for write

Returns:

non zero value if write operation failed
