This graph shows which files directly or indirectly include this file:

Macros
#define	CPU_FLASH_BASE (0)
	Per default, we expect the internal flash to start at address 0.

#define	FLASHPAGE_WRITE_BLOCK_SIZE
	For raw writings to the flash, this constant must define the minimum write length allowed by the MCU.

#define	FLASHPAGE_WRITE_BLOCK_ALIGNMENT
	The buffers to be written to the flash MUST be aligned, as well as the address on which the buffer is written to the flash. This variable must be defined for that purpose, according to the MCU align requirements.

Enumerations
enum	{ FLASHPAGE_OK = 0, FLASHPAGE_NOMATCH = -1 }
	Return values used in this interface. More...

Functions
static void *	flashpage_addr (unsigned page)
	Translate the given page number into the page's starting address. More...

static unsigned	flashpage_page (void *addr)
	Translate the given address into the corresponding page number. More...

void	flashpage_erase (unsigned page)
	Erase the given page. More...

void	flashpage_write_page (unsigned page, const void *data)
	Write the given page with the given data. More...

void	flashpage_write (void target_addr, const void data, size_t len)
	Write any number of data bytes to a given location in the flash memory. More...

void	flashpage_read (unsigned page, void *data)

int	flashpage_verify (unsigned page, const void *data)
	Verify the given page against the given data. More...

int	flashpage_write_and_verify (unsigned page, const void *data)
	Write the given page and verify the results. More...
