Storage use cases
- Boot from the primary storage device: Store the required images to boot up the device by reading the images such as XBL, AOP, Qualcomm Trusted Execution Environment (TEE), and kernel, from storage.
- Save user-specific data: Store customized information such as videos, photos, and documents.
- Support read-only logical unit number (LUN)/region: Store images such as TEE and CDT. LUN is an independent processing unit on a UFS device.
- Stores data in an authenticated, access-controlled, replay-protected manner in RPMB LUN/partition: Replay protected memory block (RPMB) is a well-known LUN (WLUN) in UFS device and a special partition in eMMC.
- See Hardware SoCs that are supported on Qualcomm Linux.
- Configure the device to boot from only one storage source. Use the second source only to store files. If both have bootable files, the system might crash or behave unpredictably.
- Detailed information on the storage hardware architecture is available to licensed developers with authorized access. For more information, see Qualcomm Linux Storage Guide - Addendum.
