Function Details

int ext_fat_config_snapshot ( elxu_device_t * device )

Issue configure EFD snapshot mailbox command.

Description: The OPCODE_COMMON_EXT_FAT_CONFIGURATION_SNAPSHOT mailbox command is issued. The command returns total log entries in the snapshot buffer.

Parameters

device Device descriptor.

Returns: Returns the length of snapshot EFD log entries on success; negative error code on failure.

Definition at line 268 of file elxu_sky.c.

int ext_fat_read_string_table	(	elxu_device_t *	device,
		mbox_ext_fat_read_string_params_t *	tblinfo,
		uint32_t	tbl_info_len,
		uint32_t	bytes_to_read,
		uint32_t	bytes_read
	)

Issue EXT_FAT_READ_STRING_TABLE mailbox command.

Description: The OPCODE_COMMON_EXT_FAT_READ_STRING_TABLE mailbox command is issued. The upper layer has to provide a number of bytes to be retrieved and the number of bytes already retrieved. The function returns the response param part of ioctl_common_ext_fat_read_string_table_t structure.

Parameters

device	Device descriptor.
tblinfo	Pointer to the param response structure.
tbl_info_len	Param response structure length.
bytes_to_read	Bytes to read.
bytes_read	Bytes already read.

Returns: Returns 0 on success; or a negative error code value on failure.

Definition at line 387 of file elxu_sky.c.

int ext_fat_retrieve_snapshot	(	elxu_device_t *	device,
		uint8_t *	buf,
		uint32_t	len,
		uint32_t	numlogs
	)

Issue retrieve EFD snapshot mailbox command.

Description: The OPCODE_COMMON_EXT_FAT_RETRIEVE_SHAPSHOT mailbox command is issued. Because of BSG limitations only 32 logs are requested per read. Upper layer executing OPCODE_COMMON_EXT_FAT_CONFIGURATION_SNAPSHOT mailbox command already knows the total number of log entries.

Parameters

device	Device descriptor.
buf	The EFD snapshot data buffer.
len	The buffer length.
numlogs	The number of logs to retrieve.

Returns: Returns 0 on success; or a negative error code value on failure.

Definition at line 304 of file elxu_sky.c.

int fat_info ( elxu_device_t * device )

Return length of FAT.

Description: Issues MANAGE_FAT mailbox command and returns the length of the FAT.

Parameters

device Device descriptor.

Returns: Returns the length of the FAT on success; negative error code on failure.

Definition at line 156 of file elxu_sky.c.

int fat_read	(	elxu_device_t *	device,
		uint8_t *	buffer,
		uint32_t	bufferLength
	)

Read FAT.

Description: Reads FAT into buffer.

Parameters

device	Device descriptor.
buffer	Read buffer.
bufferLength	Read buffer length.

Returns: Returns the number of bytes read on success; negative error code on failure.

Definition at line 175 of file elxu_sky.c.

int get_ext_fat_capabilities	(	elxu_device_t *	device,
		uint32_t	parameter_type,
		ext_fat_config_params_t *	params,
		uint32_t	paramsLength
	)

Issue EFD get capabilities mailbox command.

Description: The COMMON_GET_EXT_FAT_CAPABILIEIS mailbox command is issued. WARNING: this command will return a variable amount of data based on the configuration. There are BSG limitations that may keep all data from being correctly returned.

Parameters

device	Device descriptor.
Parameter_type	parameter type (0 for default, 1 for current set).
params	Pointer to ext_fat_config_params_t structure.
paramsLength	Length of parameters structure.

Returns: Returns 0 on success; or a negative error code value on failure.

Definition at line 236 of file elxu_sky.c.

static int image_load_common	(	elxu_device_t *	device,
		dir_t	direction,
		uint32_t	op_type,
		uint8_t *	buffer,
		uint32_t	bufferLength
	)

Description: Read or write UFI flash image. The request is broken up into a series of requests.

Parameters

device	Pointer to device descriptor.
direction	Of transfer.
op_type	UFI flash component to update.
buffer	Pointer to memory buffer with flash data.
bufferLength	Length of flash data.

Returns: Returns 0 on success; or a negative error code value on failure.

Definition at line 109 of file elxu_sky.c.

int ufi_image_download	(	elxu_device_t *	device,
		uint32_t	op_type,
		uint8_t *	buffer,
		uint32_t	bufferLength
	)

Description: The flash image given by 'buffer' for 'bufferLength' is passed to the flash. 'op_type' defines which flash image component is to be written.

Parameters

device	Pointer to device descriptor.
op_type	flash component to update.
buffer	Pointer to memory buffer with flash data.
bufferlength	Length of flash data.

Returns: Returns 0 on success; or a negative error code value on failure.

Definition at line 67 of file elxu_sky.c.

int ufi_image_upload	(	elxu_device_t *	device,
		uint32_t	op_type,
		uint8_t *	buffer,
		uint32_t	bufferLength
	)

Description: The flash image 'op_type' is read into 'buffer'

Parameters

device	Pointer to device descriptor.
op_type	flash component to update.
buffer	Pointer to memory buffer with flash data.
bufferLength	Length of flash data.

Returns: Returns 0 on success; or a negative error code value on failure.
