DEMO program with ATECC608A on ESP-WROOM-32SE

Overview

Running demo programs with ATECC608A on 32SE by setting WOLFSSL_ESPWROOM32SE definition

Including the following examples:

  • simple TLS client/server
  • crypt benchmark

The user_settings.h file enables some of the hardened settings.

Requirements

  1. ESP-IDF development framework: https://docs.espressif.com/projects/esp-idf/en/latest/get-started/

  2. Microchip CryptoAuthentication Library: https://github.com/MicrochipTech/cryptoauthlib

Setup

  1. Comment out #define WOLFSSL_ESP32 in /path/to/wolfssl/IDE/Espressif/ESP-IDF/user_settings.h
    Uncomment out #define WOLFSSL_ESPWROOM32SE in /path/to/wolfssl/IDE/Espressif/ESP-IDF/user_settings.h
    • Note: crypt test will fail if enabled WOLFSSL_ESPWROOM32SE
  2. wolfSSL under ESP-IDF. Please see README.md
  3. CryptoAuthentication Library under ESP-IDF. Please see README.md

Configuration

  1. The user_settings.h can be found in /path/to/esp-idf/components/wolfssl/include/user_settings.h

Build examples

  1. See README in each example folder
