Tool/software:

Hello,

As describle in this thread, Setting for DCSM in Sysconfig, we want to write a function to program OTP area, include CMAC key, JTAGENABLE, JTAG Unlock KEY and other value.

Are there some advice or examples you could provide?

    Hello,

    The easiest way to configure all of these fields is through the DCSM module in SysConfig. I would suggest programming JTAGENABLE last and programming with the "verify" option disabled in the CCS On-chip flash tool.

    Thank you,

    Luke

    Because we want to enable the JTAG Lock in the final step of offline. And the JTAG PSWD is different from each device.

    In that case I would suggest programming a .out file containing the DCSM settings with JTAGLOCK disabled first. Once your settings have been finalized, enable JTAGLOCK in SysConfig and program the same .out file again.

    Deciding on how to program different JTAG passwords on each device is up to you.

    Let me know if you have additional questions.

    Thank you,

    Luke
