调用Fapi_issueProgrammingCommand（）,不报错，但是数据没有存储进去，之后Fapi_getFsmStatus（）,报0x30错误，但是flash区域我看过全是0xffff，没有数据
用Fapi_doBlankCheck（）函数也校验过这片区域全是0xffff，不应该写入不进去

// each loop iteration until the whole buffer is programmed.
//
// Remember that the main array flash programming must be aligned to
// 64-bit address boundaries and each 64 bit word may only be programmed
// once per write/erase cycle. Meaning the length of the data buffer
// (3rd parameter for Fapi_issueProgrammingCommand() function) passed
// to the program function can only be either 4 or 8.
//
// Program data in Flash using "AutoEccGeneration" option.
// When AutoEccGeneration option is used, Flash API calculates ECC for the
// given 64-bit data and programs it along with the 64-bit main array data.
// Note that any unprovided data with in a 64-bit data slice
// will be assumed as 1s for calculating ECC and will be programmed.
//
// Note that data buffer (Buffer) is aligned on 64-bit boundary for verify
// reasons.
//
// Monitor ECC address for Sector6 while programming with AutoEcc mode.
//
// In this example, 0x100 bytes are programmed in Flash Sector6
// along with auto-generated ECC.
