README.md

Rowley CrossWorks ARM Project for wolfSSL and wolfCrypt

This directory contains a CrossWorks solution named wolfssl.hzp.

Inside are three projects:

  1. libwolfssl: This generates a library file named "libwolfssl_ARM_Debug/libwolfssl_v7em_t_le_eabi.a"
  2. benchmark: This is a sample benchmark application. It runs the "benchmark_test" suite repeatedly until a failure occurs.
  3. test: This is a sample test application. It runs "wolfcrypt_test" suite suite repeatedly until a failure occurs.

Prerequisits

You will need to install the "Freescale Kinetis CPU Support Package" in the Rowley Package Manager under Tools -> Pacakge Manager.

Harware Support

All hardware functions are defined in kinetis_hw.c and are currently setup for a Freescale Kinetis K64 Coretx-M4 microcontroller. This file can be customized to work with other Kinetis microcontrollers by editing the top part of the file. Testing for this project was done with the Freescale Kinetis MK64FN1M0xxx12 using the TWR-K64F120M.

To create support for a new ARM microcontroller the functions in hw.h will need to be implemented.

Also you will need to configure the ARM Architecture and ARM Core Type in the "Solution Properties" -> "ARM". Also the "Target Processor" in each of the projects ("Project Properties" -> "Target Processor")

Hardware Crypto Acceleration

To enable Freescale MMCAU:

  1. Download the MMCAU library.
  2. Copy the lib_mmcau.a and cau_api.h files into the project.
  3. Enable the FREESCALE_MMCAU define in user_settings.h and make sure its value is 1.
  4. Add the lib_mmcau.a file to Source Files in the application project.

Project Files

  • arm_startup.c: Handles startup from reset_handler. Disabled watchdog, initializes sections, initializes heap, starts harware and starts main.
  • benchmark_main.c: The main function entrypoint for benchmark application.
  • hw.h: The hardware API interface. These hardware interface functions are required for all platforms.
  • kinetis_hw.c: The most basic hardware implementation required for Kinetis.
  • test_main.c: The main function entrypoint for test application.
  • user_libc.c: Defines stubs for functions required by libc. It also wraps hardware functions for UART, RTC and Random Number Generator (RNG).
  • user_settings.h: This is the custom user configuration file for WolfSSL.

Functions required by the WolfSSL Library

If you are writting your own application, the following functions need to be implemented to support the WolfSSL library:

  • double current_time(int reset): Returns a doulbe as seconds.milliseconds.
  • int custom_rand_generate(void): Returns a 32-bit randomly generated number.
