Detailed Description

Function Documentation

void nrf_dfu_validation_init

(

void

)

Function for module initialization.

Function checks if there is a valid init packet in DFU settings written in flash.

nrf_dfu_result_t nrf_dfu_validation_init_cmd_append	(	uint8_t const *	p_data,
		uint32_t	length
	)

Function called on reception of fragment of init command.

Parameters

[in]	p_data	Init command fragment.
[in]	length	Init command fragment size.

Returns

Operation result. See nrf_dfu_result_t

nrf_dfu_result_t nrf_dfu_validation_init_cmd_create

(

uint32_t

size

)

Function called on reception of init command creation request.

Parameters

[in]

size

Size of incoming init packet.

Returns

Operation result. See nrf_dfu_result_t

nrf_dfu_result_t nrf_dfu_validation_init_cmd_execute	(	uint32_t *	p_dst_data_addr,
		uint32_t *	p_data_len
	)

Function for validating init command.

If init command is successfully validated Bank 1 details are written to out parameters.

Until nrf_dfu_validation_init_cmd_create is called, this function can be called again after the first time without side effects to retrieve address and length.

Parameters

[out]	p_dst_data_addr	Bank 1 start address if validation is successful.
[out]	p_data_len	Bank 1 length if validation is successful.

Returns

Operation result. See nrf_dfu_result_t

bool nrf_dfu_validation_init_cmd_present

(

void

)

Function for inquiring whether a valid init command has been received.

Returns

true if there is a valid init command. This can be true at boot time if the device was reset during a DFU operation.

void nrf_dfu_validation_init_cmd_status_get	(	uint32_t *	p_offset,
		uint32_t *	p_crc,
		uint32_t *	p_max_size
	)

Function for getting init command status.

Parameters

[out]	p_offset	Current offset.
[out]	p_crc	Current CRC.
[out]	p_max_size	Maximum size of init command.

nrf_dfu_result_t nrf_dfu_validation_post_data_execute	(	uint32_t	dst_data_addr,
		uint32_t	data_len
	)

Function for postvalidating the update. Function is called once all data is received.

Parameters

[in]	dst_data_addr	Bank 1 start address.
[in]	data_len	Bank 1 length.

Returns

Operation result. See nrf_dfu_result_t
