 Hello and welcome on the session. My name is Sirius Wilczek and I would like to show you how to create an external loader. As you know today's application required more and more memory space. This session show you how to integrate additional QuadSPA memory to your embedded system. This presentation is split into two parts. In the first part we will touch a bit of theory and in the second part we will create an external loader for ST Discovery board. In the theory we will have a look to the main question. What is the external loader? Then I will present you few slides about QuadSPA interface and external memory command definition. The hand zone is split into three parts. Firstly we will create and set up project in Cubemix Perspective. Then we will implement and validate QuadSPA functionality in project running from main flash of the processor. And after that when we have working code in main flash we will add needed files and change basic projects to external loader. Pre-requisites for this session are ASTEM32Cube IDE Developing Tool ASTEM32Cube Programming Tool Your Hardware ASTEM32F769 Discovery Board In my case an external memory data sheet.
