FlashArrayIntegrity problem(MPC5744P)

Dear all:

when i test FlashArrayIntegrityCheck this function on our mpc5744p board, i found this function will crash. I don't know why this is happen, is parameters problem ? or others? is there any similar example to show me how to use this function? please?

static uint32_t FlashArrayIntegrity_Check(PSSD_CONFIG pSSDConfig,
            UINT32 lowEnabledBlocks,
            UINT32 midEnabledBlocks,
            UINT32 highEnabledBlocks,
               N256K_BLOCK_SEL n256KEnabledBlocks,
            UINT8 breakOption,
            UINT8 addrSeq,
            PMISR pMisrValue,
            PCONTEXT_DATA pCtxData)
{
           UINT32 returnCode;
          UINT32 demoResult;

returnCode = pFlashArrayIntegrityCheck(pSSDConfig,
            lowEnabledBlocks,
            midEnabledBlocks,
            highEnabledBlocks,
            n256KEnabledBlocks,
            breakOption,
            addrSeq,
            pMisrValue,
            pCtxData);

    if(C55_OK == returnCode)
    {
           demoResult = WaitOperationFinish(pSSDConfig, C55_MODE_OP_PROGRAM, pCtxData);
     }
    else
    {
        demoResult = DEMO_FAIL;
    }

return (demoResult);

}

Hi,

what does it mean that "this function will crash"?

Notice that the FlashArrayIntegrityCheck() function must be executed from RAM. I guess that this could be the reason. From reference manual:

If this doesn't help, let me know and I can create some simple SW example.

Regards,

Lukas

thanks ,

can you create one similar example for us ?

this function will crash means : this function will lead to the entire program crash.

Ok, I will try to find some time to do that tomorrow or on Monday.
