 # Azure RTOS LevelX

-LevelX provides NAND and NOR flash wear leveling facilities to embedded applications. Since both NAND and NOR flash memory can only be erased a finite number of times, it’s critical to distribute the flash memory use evenly. This is typically called “wear leveling” and is the purpose behind LevelX. LevelX presents to the user an array of logical sectors that are mapped to physical flash memory inside of LevelX. Applications may use LevelX in conjunction with FileX or may read/write logical sectors directly. LevelX is designed for fault tolerance. Flash updates are performed in a multiple-step process that can be interrupted in each step. LevelX automatically recovers to the optimal state during the next operation.

+## Getting Started

-Documentation for this library can be found here: https://github.com/azure-rtos/levelx/releases/download/v6.0_rel/Azure_RTOS_LevelX_User_Guide.pdf
+Azure RTOS LevelX as part of Azure RTOS has been integrated to the semiconductor's SDKs and development environment. You can develop using the tools of choice from [STMicroelectronics](https://www.st.com/content/st_com/en/campaigns/x-cube-azrtos-azure-rtos-stm32.html), [NXP](https://www.nxp.com/design/software/embedded-software/azure-rtos-for-nxp-microcontrollers:AZURE-RTOS), [Renesas](https://github.com/renesas/azure-rtos) and [Microchip](https://mu.microchip.com/get-started-simplifying-your-iot-design-with-azure-rtos).

-# Understanding inter-component dependencies
+See [Overview of Azure RTOS LevelX](https://learn.microsoft.com/azure/rtos/levelx/overview-levelx) for the high-level overview, and all documentation and APIs can be found in: [Azure RTOS LevelX documentation](https://learn.microsoft.com/azure/rtos/levelx/).

-The main components of Azure RTOS are each provided in their own repository, but there are dependencies between them--shown in the following graph--that are important to understand when setting up your builds.

+The main components of Azure RTOS are each provided in their own repository, but there are dependencies between them, as shown in the following graph. This is important to understand when setting up your builds.

 ![dependency graph](docs/deps.png)

-# Building and using the library
+> You will have to take the dependency graph above into account when building anything other than ThreadX itself.

-## Prerequisites
+### Building and using the library

-Install the following tools:
+Instruction for building the LevelX as static library using Arm GNU Toolchain and CMake. If you are using toolchain and IDE from semiconductor, you might follow its own instructions to use Azure RTOS components as explained in the [Getting Started](#getting-started) section.

-* [CMake](https://cmake.org/download/) version 3.0 or later
-* [GCC compilers for arm-none-eabi](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
-* [Ninja](https://ninja-build.org/)
+1. Install the following tools:

-## Cloning the repo
+    * [CMake](https://cmake.org/download/) version 3.0 or later
+    * [Arm GNU Toolchain for arm-none-eabi](https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads)
+    * [Ninja](https://ninja-build.org/)

-```bash
-$ git clone https://github.com/azure-rtos/levelx.git
-```
+1. Build the [ThreadX library](https://github.com/azure-rtos/threadx#building-and-using-the-library) as the dependency.

-## Building as a static library
+1. Cloning the repo.

-Each component of Azure RTOS comes with a composible CMake-based build system that supports many different MCUs and host systems. Integrating any of these components into your device app code is as simple as adding a git submodule and then including it in your build using the CMake command `add_subdirectory()`.
+    ```bash
+    $ git clone --recursive https://github.com/azure-rtos/levelx.git
+    ```

-While the typical usage pattern is to include threadx into your device code source tree to be built & linked with your code, you can compile this project as a standalone static library to confirm your build is set up correctly.
+1. Define the features and addons you need in `lx_user.h` and build together with the component source code. You can refer to [`lx_user_sample.h`](https://github.com/azure-rtos/levelx/blob/master/common/inc/lx_user_sample.h) as an example.

-```bash
-$ cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=cmake/cortex_m4.cmake -GNinja .
+1. Building as a static library

-$ cmake --build ./build

+## Security

 Azure RTOS provides OEMs with components to secure communication and to create code and data isolation using underlying MCU/MPU hardware protection mechanisms. It is ultimately the responsibility of the device builder to ensure the device fully meets the evolving security requirements associated with its specific use case.
