Azure RTOS 6.1

About this release

This is an updated release of Azure RTOS that includes multiple bug fixes, as well as adding a number of additional MCU architecture and developer IDE options.

Azure RTOS is based on the industry leading ThreadX RTOS with well over 6.2 Billion deployments – everything from mobile phones and fitness trackers, to security systems and spacecraft. Azure RTOS is a small, fast, reliable, and easy-to-use real-time operating system (RTOS) for connecting deeply embedded sensors, devices, and gateways from the edge to the Internet of Things (IoT). Azure RTOS also represents one of the most comprehensive embedded run-time solutions, including middleware components FileX, GUIX, NetX/NetX Duo, and USBX. Most popular MCU/MPUs (32/64bit) are supported along with most popular development tools.

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.
