Hi Youjun,

Could you share your dcsm.asm file?

Thank you,

Luke

Zone2 not used.

thanks

Can you try disabling the "reset target before flash programming operations" option and unlock the DCSM zone before programming and try again?

how to disabe the option?

Hi Youjun,

This is a checkbox in the CCS On-Chip flash tool and/or Uniflash that is checked by default. Are you using Uniflash or the CCS On-Chip flash tool or Uniflash?

Thank you,

Luke

thanks Luke

Hi Luke:

    I have a question.

I have a empty MCU,download the hex(have dcsm start setting) file by uniflash,when power on ,after the mcu reset,at the beginning of main(),read the 128-bits of the CSM password.

the password is default value or setting value?what is timing of  the dcsm working?

Hi Youjun,

I'm not sure whether OTP settings can be programmed via a hex file. Can you check the  memory browser at address 0x78040 after programming?

What do you mean by "what is the timing of the dcsm working?"

Thank you,

Luke
