This video introduces the TrustZone®-based security on PIC32CM LSx Microcontrollers. There are two microcontrollers based on LSx that are PIC32CM LS00 and LS60. In this video, we will show you how to create a simple TrustZone®-based application on Microchip's PIC32CM LS60 and LS00 based on Cortex®-M23 32-bit microcontroller using MPLAB Code Configurator. This application demonstrates the TrustZone® feature on the PIC32CM LS60 and LS00 microcontroller (MCU). The application has two projects pertaining to Secure and Non-Secure modes of PIC32CM LS60/LS00 that work together on the same MCU and offers security isolation between the trusted and the non-trusted resources in the device. The Secure mode application reads the current room temperature from the temperature sensor on the I/O1 Xplained Pro Extension Kit every 500 milliseconds. Further, the application writes the temperature readings to EEPROM and reads when a request is received from the Non-secure mode application. Also, a green LED (LED0) is toggled every time the temperature display request is received from the Non-secure mode application. The periodicity of the temperature values reading can be changed to 1 second, 2 seconds, 4 seconds, and back to 500 milliseconds whenever the user presses the switch SW0 on the PIC32CM LS60 Curiosity Pro Evaluation Kit. The temperature readings are transferred to the Non-secure mode application when it requests to Secure the application through Non-Secure Callables (NSC). The Non-secure mode application requests the Secure mode application the temperature values and prints them on a serial console once it receives from the Secure mode application. Further, when it gets a request from the user (in the form of a key press on the serial console), it will request the Secure mode application to retrieve the last five stored temperature values in the EEPROM. The Non-secure application prints the last five stored temperature values on the console. Also, a red LED (LED1) is toggled every time the temperature values are read from EEPROM. Note: The difference between the PIC32CM LS00 and LS60 MCU is that the LS60 is having a TrustZone® and TrustFLEX ECC608 Secure Subsystem whereas the LS00 just has the TrustZone® Technology. The remaining features are the same in both MCUs.
