hello , thesesdays im trying to make some flash residence bootloader for mpc5674f

i found some reference pdf and project which is for mpc5634m and ssd driver

and below code is reference things... but it's not working

however, 5634m code is working.. i dont why and how it is working...

is there a someon who can explane to me?

/* Erase all blocks (except area occupied by bootloader) in low and mid addr space of flash array 0 */
// it is a 5634m code

// lowEnabledBlocks = 0x000003F8;
// midEnabledBlocks = 0x00000003;
// highEnabledBlocks = 0x00000000;

/* Select all blocks in low addr space except block 0 */
   #if (!RUN_IN_FLASH)
    lowEnabledBlocks = (0xFFFFFFFF >> (32 - ssdConfig.lowBlockNum));
   midEnabledBlocks = 0x00000000;
   highEnabledBlocks = 0x00000000;

returnCode = pFlashErase( &ssdConfig,
                            shadowFlag,
                           lowEnabledBlocks,
                           midEnabledBlocks,
                           highEnabledBlocks,
                           (tpfNullCallback)NULL_CALLBACK );
if ( C90FL_OK != returnCode )
{
      return(FlashEraseError);
}
#endif

    lowEnabledBlocks = 0x00000000;
    midEnabledBlocks = (0xFFFFFFFF >> (32 - ssdConfig.midBlockNum));
    highEnabledBlocks = 0x00000000;
    returnCode = pFlashErase( &ssdConfig, shadowFlag, lowEnabledBlocks, midEnabledBlocks, highEnabledBlocks, (tpfNullCallback)NULL_CALLBACK );
    if ( C90FL_OK != returnCode )
    {
        return(FlashEraseError);
    }

    /* Select all blocks in high addr space */
    lowEnabledBlocks = 0x00000000;
    midEnabledBlocks = 0x00000000;
    highEnabledBlocks = (0xFFFFFFFF >> (32 - ssdConfig.highBlockNum));
    returnCode = pFlashErase( &ssdConfig, shadowFlag, lowEnabledBlocks, midEnabledBlocks, highEnabledBlocks, (tpfNullCallback)NULL_CALLBACK );
    if ( C90FL_OK != returnCode )
    {
        return(FlashEraseError);
    }

Hi, could you explain "it's not working"? What issue you are facing?

For MPC5674F, following SSD is supposed to be used:
