CCS/TMS320F28377D: DCSM OTP programming only successfully on CPU1 zone1

Hi,

You have programmed LINKPOINTER3 value 0xFFFFFFF1  which is not valid. What about LINKPOINTER1 and LINKPOINTER2 ? Are these correct and remain to default value of 0xFFFF_FFFF ?

For Zone2 and CPU2 settings, have you checked the map file to confirm that those section are used in map file?

Regards,

Hi Vivek,

LINKPOINTER1 and LINKPOINTER2 remain to default value of 0xFFFF_FFFF.

I didn't use map file to define flash and dcsm otp.  I  downloaded  program API algorithm to RAM  through SCI bootloader.  Then sent data to RAM ,  and  run program API algorithm  in RAM. 

code:

    u32Index = 0x78000;

        for(k=0; k < 0x80; k++)
        {
            for(i=0; i < 8; i++)
            {
                wordData = 0x0000;
                byteData = 0x0000;
                while(SciaRegs.SCIRXST.bit.RXRDY != 1) { }
                wordData = SciaRegs.SCIRXBUF.bit.SAR;
                while(SciaRegs.SCIRXST.bit.RXRDY != 1) { }
                byteData = SciaRegs.SCIRXBUF.bit.SAR;
                // form the wordData from the MSB:LSB
                wordData |= (byteData << 8);
                Buffer[i] = wordData;
            }

       //     if(k==0x40)
        //    {
        //        DcsmCommonRegs.FLSEM.all = 0xA502;
         //   }

            if((k==0x3)||(k==0x43))
            {
                u32Index+= 4;

                Buffer[0] = Buffer[4];
                Buffer[1] = Buffer[5];
                Buffer[2] = Buffer[6];
                Buffer[3] = Buffer[7];

                oReturnCheck = Fapi_issueProgrammingCommand((uint32 *)u32Index, Buffer, 4, 0, 0, Fapi_AutoEccGeneration);

                u32Index+= 4;
            }

            else
            {
                oReturnCheck = Fapi_issueProgrammingCommand((uint32 *)u32Index, Buffer, 8, 0, 0, Fapi_AutoEccGeneration);

                u32Index+= 8;
            }

         //   oReturnCheck = Fapi_issueProgrammingCommand((uint32 *)u32Index, Buffer, 8, 0, 0, Fapi_AutoEccGeneration);
         //   oReturnCheck = Fapi_issueProgrammingCommand((uint32 *)u32Index, Buffer, 16, 0, 0, Fapi_DataOnly);

            // Wait until the Flash program operation is over
            while(Fapi_checkFsmForReady() == Fapi_Status_FsmBusy);

            if(oReturnCheck != Fapi_Status_Success)
            {
              // Check Flash API documentation for possible errors
            //   Example_Error(oReturnCheck);
               while(!SciaRegs.SCICTL2.bit.TXEMPTY) { }
               SciaRegs.SCITXBUF.bit.TXDT = 0x62;
           //    SciaRegs.SCITXBUF.bit.TXDT = oReturnCheck;
            }
            else
            {
                while(!SciaRegs.SCICTL2.bit.TXEMPTY) { }
                SciaRegs.SCITXBUF.bit.TXDT = 0x58;
            }


        //    u32Index+= 8;

        }

When  u32Index = 0x80000;  wirte to flash,  there was  no problem.

Hi,

Are there any other suggestion about why can't program otp successfully on zone2?

Hi Fang,

Can you share the CPU1  Zone2 security setting which you are trying to program? Also if you could connect to CCS and provide the snapshot of CCS memory watch view for Zone2 security setting (0x78200), it'll be helpful.
