Detailed Description

Device Firmware Update Bank handling module interface.

This header is intended for shared definition and functions between single and dual bank implementations used for DFU support. It is not supposed to be used for external access to the DFU module.

Macro Definition Documentation

#define APP_TIMER_PRESCALER   0

Value of the RTC1 PRESCALER register.

#define DFU_TIMEOUT_INTERVAL   APP_TIMER_TICKS(120000, APP_TIMER_PRESCALER)

DFU timeout interval in units of timer ticks.

#define IMAGE_WRITE_IN_PROGRESS

(

)

(m_data_received > 0)

Macro for determining is image write in progress.

#define IS_UPDATING_APP

(

START_PKT

)

((START_PKT).dfu_update_mode & DFU_UPDATE_APP)

Macro for determining if a Application update is ongoing.

#define IS_UPDATING_BL

(

START_PKT

)

((START_PKT).dfu_update_mode & DFU_UPDATE_BL)

Macro for determining if a Bootloader update is ongoing.

#define IS_UPDATING_SD

(

START_PKT

)

((START_PKT).dfu_update_mode & DFU_UPDATE_SD)

Macro for determining if a SoftDevice update is ongoing.

#define IS_WORD_SIZED

(

SIZE

)

((SIZE & (sizeof(uint32_t) - 1)) == 0)

Macro for checking that the provided is word sized.

Typedef Documentation

typedef uint32_t(* dfu_bank_activate_t)(void)

Type definition of function used for activating of the software image received.

Returns

NRF_SUCCESS If the image has been successfully activated any other NRF_ERROR code in case of a failure.

typedef void(* dfu_bank_prepare_t)(uint32_t image_size)

Type definition of function used for preparing of the bank before receiving of a software image.

Parameters

[in]

image_size

Size of software image being received.
