.\Library\

• CMSIS
  Cortex® Microcontroller Software Interface Standard (CMSIS) V6.1.0 definitions by Arm® Corp.

  M3351 CMSIS-Drivers do not guarantee thread safety and Cache coherence. The source and RTE_Device header files are in the "Driver\Source" sub-folder. Please add source files and copy RTE_Device header files into your project. Projects can define PRJ_RTE_DEVICE_HEADER macro to include the private RTE_Device.h.

• Commu
  Helper functions of communication protocols, e.g., XMODEM.

• CryptoAccelerator
  Crypto accelerator source code for mbedtls.

• Device
  CMSIS compliant device header files.

• LlsiYcableLib
  LLSI library source code.

• StdDriver
  All peripheral driver header and source files.

• Storage
  Disk I/O modules for FatFs.

• UsbHostLib
  USB host library source code.

.\Sample Code\

• Crypto
  Crypto sample code using Mbed TLS library.

• FreeRTOS
  Simple FreeRTOS™ demo code.

• Hard_Fault_Sample
  Show hard fault information when hard fault happened.

  The hard fault handler shows some information including program counter, which is the address where the processor is executed when the hard fault occurs. The listing file (or map file) can show what function and instruction that is.

  It also shows the Link Register (LR), which contains the return address of the last function call. It can show the status where CPU comes from to get to this point.

• ISP
  Sample code for In-System-Programming.

• NuMaker-M3351KI
  Sample code for NuMaker-M3351KI board.

• PowerManagement
  Sample code for power management.

• SecureApplication
  Sample code for secure application.

  VS Code projects require Python 3.12 at least for post-build.

• StdDriver
  Sample code to demonstrate the usage of M3351 series MCU peripheral driver APIs.

• Template
  Project template for M3351 series MCU.

• TrustZone
  Demo of secure code and non-secure code.

• XOM
  Demonstrate how to create XOM library and use it.

.\ThirdParty\

• FatFs
  An open-source FAT/exFAT file system library. A generic FAT file system module for small embedded systems.

• FreeRTOS
  Real-time operating system for microcontrollers.

• mbedtls
  Mbed TLS offers an SSL library with an intuitive API and readable source code, so you can actually understand what the code does.

.\Tool\

• imgtool.exe
  Used to perform the operations that are necessary to manage keys and sign images.
