7.5 Set SWD Password

The SWD interface can be configured to be disabled, enabled, or enabled with a 128-bit password by writing the BOOTCFG0 and SWDPW registers in NONMAIN. See the device Technical Reference Manual and Cybersecurity Enablers in MSPM0 MCUs for more information about NONMAIN and SWD password. Users can follow the steps to add password on SWD.

  1. Enable and input SWD Password through sysconfig.
  2. Enable Nonmain configuration.
  3. After repowering, the device is locked.
Enable SWD PasswordFigure 7-8 Enable SWD Password
Note: SBW security only works after repowering.

Here are the steps to reprogram MSPM0 with the password. This action does not erase NONMAIN, so the password remains active unless NONMAIN is modified.

  1. In the CCS project, select targetConfigs → MSPM0xxxx.ccxml. Input password in .ccxml file. Ctrl+S to save .ccxml file.
  2. Right-click the .ccxml and select Start Project-less Debug. First select DebugAccessPasswordAuthentication. After the GEL output shows Command execution completed, select Factory Reset. For more about factory reset, refer to Section 7.1.
  3. Now, the device returns to empty and is ready to reprogram a new firmware.

Note: Enabling a password can work with CCS, IAR and Keil. Clearing passwords can only work on CCS.
