Hi,

Please check the below threads,

LPC812 IAP Copy Command not Affecting Destination

LPC 822 ISP Write to RAM echoes correctly, but OK response never received!

Have a great day,

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
