C90TFS FLASH操作问题

华夏雄鹰

KDS下使用KSDK库操作FLASH，芯片型号MK22FN1M0A，把数据写入FLASH后，读出来都是0x00，
但是读flashSSDConfig.PFlashBase + PFLASH_IFR中的数据是0xFF
参考的是KSDK1.3中的DEMO
#define LAUNCH_CMD_SIZE         0x100
#define CALLBACK_SIZE           0x80
#define TesetBufferSize        4
/* array to copy __Launch_Command func to RAM */
uint16_t __ram_func[LAUNCH_CMD_SIZE/2];
uint16_t __ram_for_callback[CALLBACK_SIZE/2]; /* length of this array depends on total size of the functions need to be copied to RAM*/
uint8 UserFlashWriteBuffer[TesetBufferSize] = {0};
uint8 UserFlashReadBuffer[TesetBufferSize] = {0};
FLASH_SSD_CONFIG flashSSDConfig =

        }
        else

        ret = FlashReadResource(&flashSSDConfig, destination, UserFlashReadBuffer, 0x0, g_FlashLaunchCommand);//结果是是0XFF
         
        for(i=0; i<TesetBufferSize; i++)

        //read
        FlashReadResource(&flashSSDConfig, destination, UserFlashReadBuffer, 0, g_FlashLaunchCommand);//结果全是0X00,应该是0,1,2,3
        printf("End");
        while(1);
}

没人回答，如何是好

KSDK1.2中是有Flash driver的对应例程的。

~\KSDK_1.2.0\examples\frdmk22f\driver_examples\flash ...

我就是根据KSDK1.3中的这个例程写的，例程里面只是把数据写进去了，没有读出来。
我调用这个函数去读ret = FlashReadResource(&flashSSDConfig, destination, UserFlashReadBuffer, 0, g_FlashLaunchCommand);
操作失败，返回FTFx_ERR_ACCERR

书山有路

这个，还是看你的啦
