no_os_flash_clear_page()

int32_t no_os_flash_clear_page	(	struct no_os_flash_dev *	dev,
		int32_t	page_no
	)

Erase a flash page.

Parameters

[in]	dev	- Pointer to the flash device handler.
[in]	page_no	- Page number.

Returns

0 in case of success, negative error code otherwise.

no_os_flash_init()

int32_t no_os_flash_init	(	struct no_os_flash_dev **	device,
		struct no_os_flash_init_param *	init_param
	)

Initialize flash controller.

Parameters

[out]	device	- Pointer to the driver handler.
[in]	init_param	- Pointer to the initialization structure.

Returns

0 in case of success, error code otherwise.
