In order to control the dependence of other components on drivers at a smaller granularity, the original peripheral drivers under the ``driver`` component were split into separate components:
For compatibility, the original ``driver`` component is still treated as an all-in-one component by registering these `esp_driver_xyz` components as its public dependencies. In other words, you do not need to modify the CMake file of an existing project, but you now have a way to specify the specific peripheral driver that your project depends on.
Originally, you may have used **linker.lf** to specify the link location of some driver functions in memory space, but now, because the location of the driver files have been moved, you need to make changes your **linker.lf** file accordingly. For example, a linker.lf file with the following entries:
The ATECC608A secure element interfacing example has been moved to `ESP Cryptoauthlib Repository <https://github.com/espressif/esp-cryptoauthlib/tree/master/examples/atecc608_ecdsa>`_ on GitHub.
This example is also part of the `esp-cryptoauthlib <https://components.espressif.com/component/espressif/esp-cryptoauthlib>`_ in the component manager registry.
