Hi,

 

In code secuirity model suppose the device is secured by some password stored in Password Loacations(PWL).

We need to unlock the same by giving exact password in KEY register. We need to know , is the .out file gets modified or

password gets written to  0x00 0AE0 − 0x00 0AE7 this location.

 

Regards,

Sulochana Kadam

    Sulochana,

    The password in the Password Locations in flash is part of your .out file. The matching value that you write into the KEY register to unlock it is written directly to registers located at 0x0AE0 - 0x0AE7. You can do this manually in CCS, or if you get tired of doing it manually, you can modified the GEL file in CCS to do it automatically on a reset, thereby always unlocking it in your debugger. Just make sure to protect the GEL file from leaving your possession as it is now a record of your password.

    Sulochana, which device are you using ? Checking your history it seems you're working on F28035, if so gel file for this device is available here:
    C:\ti\controlSUITE\device_support\f2803x\v129\DSP2803x_common\gel\ccsv5

    You simply have to edit it i.e. unlock_csm section

    Regards,
