CARD_WriteAndVerifyFlashSectorAsync

Syntax

#include <nitro/card.h>

static inline void CARD_WriteAndVerifyFlashSectorAsync( u32 dst, const void *src, u32 len, MIDmaCallback callback, void *arg);

Arguments

dst The flash memory address of the transfer destination.
This must be an integer multiple of the value obtained by the CARD_GetBackupSectorSize function.
For more about the sector size for each device, see Overview.
src Transfer source memory address.
len Byte length of the data to write.
This must be an integer multiple of the value obtained by the CARD_GetBackupSectorSize function.
For more about the sector size for each device, see Overview.
callback Completion callback function.
Specify NULL if this is unnecessary.
This callback is called from within the interrupt handler.
arg Arguments to pass to the completion callback function.
This is simply ignored if NULL was specified for callback.

Return Values

None.

Description

This function asynchronously writes data to the FLASH device and performs a comparison on that written data at the sector level.
This function immediately returns control. Use the CARD_WaitBackupAsync function to wait for processing to end. To determine the processing result, call the CARD_GetResultCode function after processing has ended.

This function simply calls a combination of the CARD_EraseFlashSector and CARD_ProgramAndVerifyFlashAsync functions internally. For more information, see the function references for these functions.

To use this function, you must first lock the access bus with the CARD_LockBackup function.

Internal Operation

This function communicates with the ARM7 processor internally via PXI.
The process will not end if PXI interrupts are not enabled.
The function uses an internal thread to execute an asynchronous process. See the description of the CARD_GetThreadPriority function for more information on this thread.
