wolfTPM/zephyr

Zephyr Project Port

Overview

This port is for the Zephyr RTOS Project, available here.

It provides the following zephyr code.

• modules/lib/wolftpm
  • wolfTPM library code
• modules/lib/wolftpm/zephyr/
  • Configuration and CMake files for wolfTPM as a Zephyr module
• modules/lib/wolftpm/zephyr/samples/wolftpm_wrap_caps
  • wolfTPM test application
• modules/lib/wolftpm/zephyr/samples/wolftpm_wrap_test
  • wolfTPM test application

How to setup as a Zephyr Module

Follow the instructions to setup a zephyr project.

Modify your project's west manifest

Add wolfTPM as a project to your west.yml:

manifest:
  remotes:
    # <your other remotes>
    - name: wolftpm
      url-base: https://github.com/wolfssl

  projects:
    # <your other projects>
    - name: wolftpm
      path: modules/lib/wolftpm
      revision: master
      remote: wolftpm

Note: wolfTPM has dependencies with wolfSSL so you need to also need to add wolfSSL into the west.yml like shown above.

Update west's modules:

west update

Now west recognizes 'wolftpm' as a module, and will include it's Kconfig and CMakeFiles.txt in the build system.

Build and Run Tests

Build and Run wolfTPM wrap Test Application

If you want to run build apps without running west zephyr-export then it is possible by setting the CMAKE_PREFIX_PATH variable to the location of the zephyr sdk and building from the zephyr directory. For example:

CMAKE_PREFIX_PATH=/path/to/zephyr-sdk-<VERSION> west build -p always -b qemu_x86 ../modules/lib/wolftpm/zephyr/samples/wolftpm_wrap_test/

build and execute wolftpm_wrap_test

cd [zephyrproject]
west build -p auto -b qemu_x86 modules/lib/wolftpm/zephyr/samples/wolftpm_wrap_test
west build -t run

Build and Run wolfTPM wrap Capabilities Application

build and execute wolftpm_wrap_caps

cd [zephyrproject]
west build -p auto -b qemu_x86 modules/lib/wolftpm/zephyr/samples/wolftpm_wrap_caps
west build -t run
