Getting Started with the PIC32CM LS00/LS60 TrustZone Projects Using

MPLAB X IDE and MCC

PIC32CM LS00/LS60 Security Concept Overview
Using the PIC32CM LS00/LS60 requires familiarity with different security features and concepts that involve TrustZone® for ARMv8-M devices. The TrustZone technology is a System-on-Chip (SoC) and MCU system-wide approach to security that enables Secure and Non-Secure code to run on an MCU. It enables creating of multiple software security domains that restrict access to selected memory, peripherals, and I/O to trusted software without compromising the system’s performance.

The user can consider the following deployment approaches:

• Single-developer approach (Customer A)
• Dual-developer approach (Customer A + Customer B)

The single-developer approach involves a unique developer (Customer A), which oversees the following:

• Developing, deploying, and protecting the Secure code
• Developing and deploying the Non-Secure code

In the dual-developer approach, the first developer (Customer A), oversees developing the secure application and its associated non-secure callable library. The secure application must be loaded in the PIC32CM LS00/LS60 NVM and protected areas. A different developer (Customer B) will then start the non-secure application development on a preprogrammed PIC32CM LS00/LS60 with limited access to secure resources (call to non-secure API only).

Figure 4-1. Single-Developer Approach

Figure 4-2. Dual-Developer Approach

This document describes how to debug an MPLAB project composed of two sub- projects (Secure and Non-Secure).

Note:
Refer to the PIC32CM LS00/LS60 Security Reference Guide (DS00003992), which describes the security features available in the Microchip PIC32CM LS00/LS60 microcontroller, which fulfill the security requirements of most embedded systems.

Compiling and Programing a First Application
Follow these steps to use the PIC32CM LS00/LS60 Curiosity Pro evaluation kit based on MPLAB X Environment.

Note:
The following steps are demonstrated based on the PIC32CM LS00 Curiosity Pro board, but are fully reproducible with a PIC32CM LS60 Curiosity Pro board.

1. Launch MPLAB X IDE.

2. Connect the evaluation kit through the DEBUG USB connector to the PC using a micro-USB cable (Standard-A to Micro-AB). When the Curiosity Pro evaluation kit is connected to the computer for the first time, the operating system will install the software drive.
   Note:
   The software driver file supports both 32-bit and 64-bit versions of Microsoft Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, and Windows 11.
   Figure 4-3. Windows Messages

3. When the Curiosity Pro board is powered, the green power LED (PWR) will glow and the MPLAB X IDE will auto-detect the connected Curiosity Pro MCU.
   Note:
   The PIC32CM5164LS00100 and PIC32CM5164LS60100 devices are programmed and debugged by the on-board embedded debugger (EDBG), therefore no external programmer or debugger tool is required.

4. From the Toolbar, select File > Open Project, or click (the project icon).
   Figure 4-4. MPLAB X IDE – Open Project

5. For example, navigate to C:\H3\csp_apps_pic32cm_le_ls\apps\trustZone\tc and open the secure_tc_ls00 projects group, which contains the secure_tc_ls00_NonSecure and secure_tc_ls00_Secure projects.

6. Open Secure and Non-Secure projects by double-clicking on each of the project.
   Note: A prompt message may appear to upgrade the DFP. Upgrade it if is requested.

7. Select Connected Hardware Tool:

   • To set the Non-Secure project as the main project: Right-Click and select Set as Main Project
     Important: When the Non-Secure project is set as the main project in a TrustZone project group, the Secure project is built first and then comes the Non-Secure project. This is possible using the project’s Loadable feature which will load all projects defined in this section before the main project as shown in the figure below. If the Secure project is set as the main project, only this project and its related memory regions will be built and programmed.
     Figure 4-5. Secure Project Under Non-Secure Loadable Project Section

   • To open the non-secure project properties: Right-Click and select Properties.

   • Select the connected PIC32CM LS00 Curiosity Pro board from the Connected Hardware Tool drop-down menu.
     Figure 4-6. Project Properties – Connected Hardware Tool

   • Click Apply, and then click OK.

8. To set breakpoints to debug the complete secure_tc solution, follow these steps:

   • Add a breakpoint on the nsc_TC0_DutyCycle_Set (duty_cycle) line in the Non-Secure project main.c file.
     Figure 4-7. Setting Breakpoint in Non-Secure main.c File
     Note:  In this case, the breakpoint is placed at the line nsc_TC0_DutyCycle_Set that calls the Non-Secure callable function named TC0_Compare8bitMatch0Set. This function is declared in the
     pic32cm_ls00_cpro_Secure_sg_veneer.lib file, which is generated once the Secure project is built.
     The call to the Secure function TC0_Compare8bitMatch0Set is done in the veneer (Secure gateway).
     

   • Add a breakpoint on the TC0_Compare8bitMatch0Set function call in the Secure project nonsecure_entry.c file, which is located at secure_tc_ls00_NonSecure > Source Files > trust zone in MPLAB X IDE. Click on the number to the left of the line to put a breakpoint.
     Figure 4-8. Setting Breakpoint in Secure nonsecure_entry.c File

   • Add a breakpoint on the bool status = false line in the Secure project plib_tc0.c file located at secure_tc_ls00_Secure > Source Files > config > pic32cm_ls00_cpro > peripheral > tc in MPLAB X IDE project tree.
     Figure 4-9. Setting Breakpoint in Secure plib_tc0.c File
     CAUTION
     When debugging the secure application veneers, only hardware breakpoints must be used to stop code execution on a Secure Gateway (SG) instruction. Using software breakpoints implies the addition of a breakpoint (BKP) instruction before an SG instruction, which triggers a Secure fault during the code execution. This behavior is normal, as the first instruction to be executed when accessing the Non-Secure Callable (NSC) region must be an SG instruction.

9. To compile and run the application, follow these steps:

   • To build and program the projects: Select Production > Make and Program Device Main Project, or click (the build icon).
   • To debug the project, select Debug > Debug Main Project, or click (the debug icon).
   • The application is programmed and the debugger breaks in the Non-Secure project at nsc_TC0_DutyCycle_Set.

10. Continue the debugging session by clicking the button.

11. As a result, the debugger will stop successively on:

    • The nsc_TC0_DutyCycle_Set (duty_cycle) function call (Non-Secure project).
    • The TC0_Compare8bitMatch0Set function call (Secure project).
    • The bool status = false line (Secure project).

12. Open MCC and update MCC Core:
