Are you a user of Micrium? If so, you will be happy to know that wolfSSL recently updated support and added TLS client and server examples to the wolfSSL embedded SSL/TLS library for Micrium!
We have also run a benchmark of our wolfCrypt/wolfSSL libraries on an NXP Kinetis K70 (Freescale TWR-K70F120M MCU) tower system board with a project built using the IAR Embedded Workbench IDE - ARM 8.32.1 (IAR ELF Linker V126.96.36.199/W32 for ARM). The details can be viewed on the wolfSSL benchmarks page.
For instructions on how to build and integrate the examples on your projects or to see the benchmark results, please see the README located in “IDE/ECLIPSE/MICRIUM”. This support is currently located in our GitHub master branch, and will roll into the next stable release of wolfSSL as well. For any questions or help getting wolfSSL up and running on your environment, please contact us at email@example.com. wolfSSL also now supports the most current version of TLS, TLS 1.3!
