 Handles Flash Access Result Events declared in pstorage_platform.h.
static uint32_t swap_state_process (cmd_queue_element_t *p_cmd, uint32_t page_number, uint32_t head_word_size, uint32_t tail_word_size)
 Function for handling flash accesses when using swap.
static uint32_t cmd_process (void)

Detailed Description

Utility functions needed for interfacing with flash through SoC APIs. SoC APIs are non blocking and provide the result of flash access through an event.

Note:
Only one flash access operation is permitted at a time by SoC. Hence a queue is maintained by this module.

Function Documentation

static void app_notify ( uint32_t  result ) [static]

Routine to notify application of any errors.

Parameters:
[in]resultResult of event being notified.

Definition at line 396 of file pstorage.c.

static uint32_t cmd_process ( void   ) [static]

Routine called to actually issue the flash access request to the SoftDevice.

Return values:
NRF_SUCCESSon success, else an error code indicating reason for failure.

Definition at line 699 of file pstorage.c.

static uint32_t cmd_queue_dequeue ( void   ) [static]

Dequeues a command element.

Return values:
NRF_SUCCESSon success, else an error code indicating reason for failure.

Definition at line 362 of file pstorage.c.

static void cmd_queue_element_init ( uint32_t  index ) [static]

Initializes command queue element.

Parameters:
[in]indexElement index being initialized.

Definition at line 267 of file pstorage.c.

static uint32_t cmd_queue_enqueue ( uint8_t  opcode,
pstorage_handle_t *  p_storage_addr,
uint8_t *  p_data_addr,
pstorage_size_t  size,
pstorage_size_t  offset 
) [static]

Routine to enqueue a flash access operation.

Parameters:
[in]opcodeIdentifies operation requested to be enqueued.
[in]p_storage_addrIdentiifes module and flash address on which operation is requested.
[in]p_data_addrIdentifies data address for flash access.
[in]sizeSize in bytes of data requested for the access operation.
[in]offsetOffset within the flash memory block at which operation is requested.
Return values:
NRF_SUCCESSon success, else an error code indicating reason for failure.
Note:
All paramater check should be performed before requesting in an enqueue.

Definition at line 312 of file pstorage.c.

Definition at line 282 of file pstorage.c.

void pstorage_sys_event_handler ( uint32_t  sys_evt )

Handles Flash Access Result Events declared in pstorage_platform.h.

Parameters:
[in]sys_evtSystem event to be handled.

Definition at line 428 of file pstorage.c.
