This section is a step-by-step instruction on how to implement encryption debugging functions.

Materials used:

  • CCS IDE
  • One code project
  • Two customized CCS scripts
  • XDS110 hardware

The customer's own application is in main.c. The specific application connects to the MCU functional software mentioned in Section 3.2.2, and are in the startup file. Also, note that the .cmd file is also changed.

The CCS script is used to set the debugger to send the related mailbox message to support the whole connection work flow and the password sending.

Note: TI has provided the code project and CCS scripts which have the demo code to achieve password-protected debug function. If users need further assistance, then contact a TI representative.
