These examples are intended as a simple starting point for your own projects. You've got the choice to use the HAL provided drivers or write your own and still use the STM32Cube generated initialization like I did for the uart driver. For each board, I've provided a STM32CubeMX project file (*.ioc), a top level Makefile and a simple main() demo creating two ChibiOS tasks (one blinking the LED, the other one sending messages over the uart).
If you want to create a new project, take a deeper look at the code generation settings in one of the example projects. You'll have to clone them manually in your new project to make everything work as expected.
Check the clock source configuration: Some nucleo boards have the 8MHz (MCO solder bridges) installed, others don't. Either read the documentation, or just look at the backside of the board for the solder jumpers labelled "MCO" (one located at the ST-Link part, one located near the controller). If they are open, you must use the internal HSI RC oscillator.
The top level Makefile includes several other makefiles:
All neccessary library files are included in the tarball. You do not need to download or install additional sources to compile the examples. The included sources might not be complete in terms of their original source, get the full Cube HAL sources from STmicro. Some of the HAL source files were modified from their original state to make my uart driver work.
At the time of writing, the STM32F410 was brand new and not yet fully supported by openocd and ChibiOS. I've made some minor modifications to ChibiOS to get it running. Thanks to Uwe Bonnes' patches, STM32F410 support is available for openocd, but since it is not yet merged to the main branch, you'll have to cherry-pick these from the git repository and compile your own openocd. Or just simply wait for the patches to be merged, this is just a matter of time. If you don't like compiling openocd yourself, you may want to check Freddie Chopins website for pre-compiled versions.
If you don't want to use the latest STM32 controllers (STM32F410, STM32F746), the latest stable openocd (0.9.0) should do the job. For STM32F746 you'll need a more recent version (0.10.0-dev).
If you don't like the STM32CubeMX approach, try ChibiOS HAL. The ChibiOS package contains quite a lot of readily compileable examples for many STM32 discovery and nucleo boards. ChibiOS HAL also provides a lot of peripheral drivers for the STM32 family.
