Updating this example's dependencies

When you feel like modifying any of this example's dependencies (Mbed Crypto, Cryptoauthlib), for example to update the secure element driver interface, you'll need to make your changes across a handful of different components.

  1. Update SE driver interface (and tests) in Mbed Crypto (mbed-crypto)
  2. Save the changes to a branch in your fork of Mbed Crypto (mbed-crypto)
  3. Update Mbed OS (mbed-os) with your Mbed Crypto fork's SE driver changes
  4. Save the changes to a branch in your fork of Mbed OS (mbed-os)
    1. cd features/mbedtls/mbed-crypto/importer
    2. Within the Makefile, edit CRYPTO_RELEASE to point to your branch
    3. Within the Makefile, edit CRYPTO_REPO_URL to point to your fork
    4. make update; if you have an mbed-crypto in a different repo already checked out, this command can fail. Use rm -rf TARGET_IGNORE/mbed-crypto/ and run make update again
    5. make all
    6. Commit your changes on a branch in your fork
  5. Update the ATECC608A driver for Mbed OS (mbed-os-atecc608a) for the interface changes
  6. Save the changes to a branch in your fork of mbed-os-atecc608a
  7. Update the Mbed OS example for ATECC608A (mbed-os-example-atecc608a)
    1. For each example subfolder you want to update:
      1. Point the mbed-os.lib file at the branch in your fork
      2. Point the mbed-os-atecc608a.lib file at the branch in your fork
      3. mbed deploy
