I bought a STM32F4 - DISCOVERY board to play with, and I succeeded to compile and run a lot of simple, led / LCD / audio project I found online. I was using the Sourcery arm compile chain for that. But my next ambition is little harder, I would like to adapt one of my existing program, based on a plugin-mechanism, on my stm32. So, I was looking for an RTOS being able to manage a simple system, in the Flash memory, or in an external SD card. I tried to set up the compilation environnement described in the big pdf describing eCos, and on the Download & Installation section on the website, I tried all the day, without any result. Do you have some good links / tuto / advices to share ? My questions are : Is it possible to use the compilation chain generated by summon-arm-toolchain, to compile eCos itself ? What about the programs I would like to run on top of eCos ? If I store my programs in the Flash, how can I reprogram the flash to change only the program, and not the kernel ? IYO, is eCOS the best OS to choose for my project ? // Are its dynamic loading mechanism easy to use ? Thank you by advance :) Valentin B -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
