Detailed Description

HAL_SPI_FLASH.

Function Documentation

hal_spi_flash_prog_page()

int hal_spi_flash_prog_page	(	uint32_t	addr,
		uint8_t *	data,
		uint32_t	data_len
	)

Programme SPI Flash page.

Note

Now one page is 256 bytes. prog_size should be smaller then 256. This function only programme one page. If user want to write more page, call this function with new page address.

Parameters

[in]	addr	Flash programme address (Starting from 0x0).
[in]	data	Programme data buffer.
[in]	data_len	Flash Programme size. This size shoudle be be smaller than sector size (4K).

Returns

See also

enum flash_error for return code.

hal_spi_flash_read()

int hal_spi_flash_read	(	uint32_t	addr,
		uint8_t *	data,
		uint32_t	size
	)

Flash read function.

Note

Read data from addr. Read data in XIP mode.

Parameters

[in]	addr	Flash read address (starting from 0x0).
[in]	data	Data buffer.
[in]	size	Data size.

Returns

See also

enum flash_error for return code.

hal_spi_flash_read_page()

int hal_spi_flash_read_page	(	uint32_t	addr,
		uint8_t *	data,
		uint32_t	size
	)

Flash read function.

Note

Read data from addr. Read data in non-XIP mode.

Parameters

[in]	addr	Flash read address (starting from 0x0).
[in]	data	Data buffer.
[in]	size	Data size. Max size is 256 bytes.

Returns

See also

enum flash_error for return code.

hal_spi_flash_sector_erase()

int hal_spi_flash_sector_erase	(	uint32_t	addr,
		uint32_t	sector_nb
	)

Erase SPI Flash sector.

Note

Now one sector is 4K bytes. erase_addr should be 4K bytes aligned. This function only erase 4K bytes. If user want to erase more sector, call this function with new sector address.

Parameters

[in]	addr	Flash erase address (Starting from 0x0)
[in]	sector_nb	sector number to erase.

Returns

See also

enum flash_error for return code.

hal_spi_flash_verify()

int hal_spi_flash_verify	(	uint32_t	addr,
		uint8_t *	data,
		uint32_t	size
	)

Verify SPI Flash data.

Note

Read data from addr, and compare data in data buffer. Only work in XIP mode.

Parameters

[in]	addr	Flash read address (starting from 0x0).
[in]	data	Data buffer.
[in]	size	Data size.

Returns

See also

enum flash_error for return code.
