TMS320F280025: 280025 The program cannot run after the dcsm password is set

Part Number: TMS320F280025


Hello, I have used dcsm function of 280025. After using the first password area to configure a password and burning the program, the program cannot start, as shown in the picture above

The program will work only if the LINKPOINTER is linked to the next security configuration area 0xFFFFFFFE,Password not written to security zone 2

the adcsm password function is disabled

  • How to set the password function of dcsm and the program can run normally

  • Hi,

    It's not clear what are you trying to do here. You have only programmed the password but left all other setting to default which is not good because with default settings of GRABRAM and GRABSECT, the RAMs and Flash sector becomes inaccessible hence it will not work. Please refer the RAM/Flash accessibility table in device TRM for more detail.

    Regards,

  • Thank you for your guidance. Could you please tell me how to set the password with Z1OTP and all ram and flash, GRABRAM and GRABSECT registers? Is B0-ZIOTP-GRABSECT 0XAAAAAAAA, and B0-ZIOTP-GRABRAM how to set to include all RAM, thank you

  • Hello, I have reviewed the detailed document and carried out the following operations again, but there will be an exception, as follows

    Use the first safety zone

    Set the password of the first security zone. I cannot start the program when I power on again

    Modify the next two registers and click the program GRABSECT1 button

    Powering back on after operation can run the program, but my XDS100V2ISO emulator can no longer connect to my hardware

    I have confirmed that the emulator connection failure is caused by my above operations,

    Do I have any other registers not set correctly

    please help me how to solve this problem, thank you

  • You have secured all the flash sectors and RAM hence you can not connect to CCS. This is ECSL feature of the device. Please refer the TRM for more detail about ECSL feature. You need to boot device in WAIT BOOT to be able to connect to CCS.
