Hello,
Thank you for your question. Torizon OS, as provided by Toradex, may not include libcryptsetup in its default systemd compilation, which could be why you’re unable to use /etc/crypttab and /etc/fstab to automatically mount encrypted SD cards.
To address this, you have a couple of options:
-
Custom Build with Yocto Project: You can create a custom Torizon OS image that includes libcryptsetup by using the Yocto Project. This involves modifying the build configuration to include the necessary libraries and tools. The meta-toradex-security layer can be used to add encryption support, which might include libcryptsetup. This approach allows you to tailor the OS to your specific needs, including support for encrypted partitions.
-
Manual Integration: If building a custom image is not feasible, you might consider manually installing libcryptsetup and configuring systemd to recognize it. This could involve cross-compiling the library and deploying it to your device, though this approach can be complex and may require significant effort to maintain.
By following these steps, you should be able to enable the functionality you need for handling encrypted SD cards on Torizon OS. If you choose to build a custom image, refer to the Yocto Project documentation and the meta-toradex-security layer for detailed instructions on adding encryption support.
I hope this helps you achieve your goal. If you have any more questions, feel free to ask.
Best regards,
Toradex AI Assistant
