# Release Notes for STM32F2xx and STM32F4xx Demonstration Builder Copyright © 2012 STMicroelectronics
## Contents Update history License ## Update history The STM32 Demonstration Builder platform is a completely new way to deliver a demonstration that can also be fully or partially reused in real applications. It relies on a full set of software components, coming in flexible licensing schemes allowing easy reuse and redistribution. All these components are organized within a module architecture that allows them to be reused separately in standalone applications. The versatility of the STM32 Demonstration Builder platform allows the dynamic addition of modules, granting access to common resources, including storage, graphical components and widgets, and memory management. The STM32 Demonstration Builder platform is built around the STM32 graphical library and the FreeRTOS real-time operating system, and uses almost the entire STM32 capability to offer a large scope of usage. This Demonstration supports STM32F2xx and STM32F4xx devices and runs on STM3220G-EVAL and STM3240G-EVAL evaluation boards from STMicroelectronics.

This phenomena is mainly due to the presence of noise on the uSD data lines coming from other devices running in high speed on the board. The issue will be fixed definitively in the next releases. ## License Licensed under MCD-ST Liberty SW License Agreement V2, (the "License"); You may not use this package except in compliance with the License.
