🚀 New Features

  • MbedTLS Upgrade
    • Upgraded MbedTLS CAL wrapper APIs for compatibility with Mbed TLS v3.6.3.1 (previously v2.28.4)

🛠 Fixes & Improvements

  • Certificate & Key Handling

    • Fixed atcacert_verify_ APIs to use correct key size macros and cal_buffer members
    • Fixed atca_mbedtls_cert_add() to correctly read public key using is_genkey check
    • Modified buffer size setting to use P256 signature size before calling atcacert_set_signature(), ensuring correct WPC certificate reads from ECC608 devices
    • Fixed ATCA_MBEDTLS guards to exclude MbedTLS code when disabled

  • HAL (Hardware Abstraction Layer)

    • Enhanced error handling for initialization (halinit) failures by adding appropriate hal_release calls
    • Updated hal_kit_hid_send() to flush any pending data from HID device input buffer before writes
    • Added validation of input parameters in hal_free_shared() and updated access permissions for shared memory in hal_linux.c
    • Updated Zephyr I2C HAL wrapper
      • Integrated latest I2C driver configuration updates from Zephyr 3.6.0
      • Now utilizes word_address parameter in hal_i2c_send() even when transmit buffer is empty (e.g., device wake-up)
    • Updated hal_esp32_i2c.c to support latest ESP-IDF library
      • Maintained backward-compatible I2C initialization and command methods
      • ⚠️ Note: i2c_config_t fields and i2c_driver_install API may be deprecated in future ESP-IDF releases. Refer to ESP-IDF official documentation.

  • Initialization & Configuration

    • Updated atcab_init_ext() to read ECC608 config zone only with ATCA_NO_POLL configuration
    • MPLAB Harmony Configurator updates
      • Added device_conf.json to define feature sets per secure element, used as base configuration for device selection
      • Updated TNG device selection to also generate Tester module files

  • Code Quality & Compliance

    • Replaced memset with pkcs11_util_memset in PKCS#11 implementation (for structure handling)
    • MISRA C:2012 & CERT C compliance
      • Addressed more REQUIRED category violations
      • Added file-based suppression lists for maximum MISRA check coverage with MPLAB Analysis tool suite

  • Build System

    • Replaced CMAKE_INSTALL_FULL_<dir> with CMAKE_INSTALL_<dir> to ensure proper handling of --prefix and cpack
