Detailed Description

Function Documentation

uint32_t nrf_dfu_mbr_compare	(	uint32_t *	p_ptr1,
		uint32_t *	p_ptr2,
		uint32_t	len
	)

Function for comparing source and target using an MBR command.

Parameters

[in]	p_ptr1	First pointer to data to compare.
[in]	p_ptr2	Second pointer to data to compare.
[in]	len	Length of the data to compare in bytes.

Return values

NRF_SUCCESS	If the content of both memory blocks is equal.
NRF_ERROR_NULL	If the content of the memory blocks differs.

uint32_t nrf_dfu_mbr_copy_bl	(	uint32_t *	p_src,
		uint32_t	len
	)

Function for copying the bootloader using an MBR command.

Parameters

[in]	p_src	Source address of the bootloader data to copy.
[in]	len	Length of the data to copy in bytes.

Returns

This function will return only if the command request could not be run. See sd_mbr_command_copy_bl_t for possible return values.

uint32_t nrf_dfu_mbr_copy_sd	(	uint32_t *	p_dst,
		uint32_t *	p_src,
		uint32_t	len
	)

Function for copying the SoftDevice using an MBR command.

Parameters

[in]	p_dst	Target of the SoftDevice copy.
[in]	p_src	Source address of the SoftDevice image to copy.
[in]	len	Length of the data to copy in bytes.

Return values

NRF_SUCCESS	indicates that the contents of the memory blocks where copied correctly.
NRF_ERROR_INVALID_LENGTH	Invalid len
NRF_ERROR_NO_MEM	if UICR.NRFFW[1] is not set (i.e. is 0xFFFFFFFF).
NRF_ERROR_INVALID_PARAM	if an invalid command is given.
NRF_ERROR_INTERNAL	indicates that the contents of the memory blocks where not verified correctly after copying.

uint32_t nrf_dfu_mbr_init_sd

(

void

)

Function for initializing the SoftDevice using an MBR command.

Return values

NRF_SUCCESS

If the SoftDevice was copied successfully. Any other return value indicates that the SoftDevice could not be copied.

uint32_t nrf_dfu_mbr_vector_table_set	(	uint32_t	address,
		uint8_t	is_temporary
	)

Function for setting the address of the vector table using an MBR command.

Parameters

[in]	address	Address of the new vector table.
[in]	is_temporary	If set to 1 the new forwarding address will not be stored in flash.

Return values

NRF_SUCCESS

If the address of the new vector table was set. Any other return value indicates that the address could not be set.
