Function Documentation

wiced_result_t wiced_hal_eflash_erase	(	uint32_t	offset,
		uint32_t	length
	)

Function wiced_hal_eflash_erase.

Erase the eflash. Erase is performed page-wise. eflash page size is 0x1000 bytes. eflash page count is 0x100.

Parameters

[in]	offset	:start offset of eflash page to be erased.
[in]	length	:length of data in byte's to be erased, erase performed page-wise.

Returns

: wiced_result_t

wiced_result_t wiced_hal_eflash_erase_whole

(

void

)

Function wiced_hal_eflash_erase_whole.

Erase the whole eflash

Returns

: wiced_result_t

uint32_t wiced_hal_eflash_get_size

(

void

)

Function wiced_hal_eflash_get_size.

Gets the sizeof the eflash

Returns

: eflash size

wiced_result_t wiced_hal_eflash_init

(

void

)

Function wiced_hal_eflash_init.

Initializes the embedded flash

Returns

: wiced_result_t

wiced_result_t wiced_hal_eflash_read	(	uint32_t	offset,
		uint8_t *	p_buffer,
		uint32_t	length
	)

Function wiced_hal_eflash_read.

Reads the data from eflash

Parameters

[in]	offset	:start offset of eflash from which data to be read, offset should be word aligned
[in]	p_buffer	:Pointer to the buffer to which data is to be read, buffer should be word aligned
[in]	length	:length of data in byte's to be read.

Returns

: wiced_result_t

wiced_result_t wiced_hal_eflash_write	(	uint32_t	offset,
		uint8_t *	p_buffer,
		uint32_t	length
	)

Function wiced_hal_eflash_write.

Writes the data to eflash.Interrupts will be locked for the duration of the write. And only writes to an already erased location is valid.

Parameters

[in]	offset	:start offset of eflash to be written, offset should be word aligned
[in]	p_buffer	:Pointer to the buffer from which data will be written, buffer should be byte, half-word, or word aligned.
[in]	length	:length of data in byte's to be written, length should be word aligned

Returns

: wiced_result_t
