HI:

    Thank you for your answer , These do not help me .

     The following is the code :  

//=================================================================

     uint8_t LPC8xx_Sector_Write(uint32_t FlashAddr, uint8_t *dat,uint32_t Size)
{
 uint32_t SectorN;
 rtv=swd_write_block(CopyRamAddr,dat,Size);
 if (rtv>0) return 1;
 SectorN=FlashAddr>>10;
 cmddat[0]=50;cmddat[1]=SectorN;cmddat[2]=SectorN;
 Flash_cmd(cmddat,3);
 rtv=LPC_FLASH_Busy();
 if (rtv>0) return 1; 
 cmddat[0]=51;
 cmddat[1]=FlashAddr;
 cmddat[2]=CopyRamAddr,;
 cmddat[3]=Size;
 cmddat[4]=12000;
 Flash_cmd(cmddat,5);
 rtv=LPC_FLASH_Busy();
 if (rtv>0) return 2; 
 return rtv;
}

//=====================================================================

1. Of course  ,first erase sector,  read this  sector   flash   is all 0xff.  flash have  data  before.

2.  then  Sector_Write,  Confirm return CMD_SUCCESS,  if  I use  error  flash address,  return  DST_ADDR_ERROR,  if I use error Size it return COUNT_ERROR, I think   this  "uint8_t LPC8xx_Sector_Write(uint32_t FlashAddr, uint8_t *dat,uint32_t Size)"   code  no error.  I don't know  it is return CMD_SUCCESS,  Why no data is written ?

3.   All data are also verified by Jlink tool
