By the way, with fpc trunc compiler you can target your board directly:

ppcrossarm -WpDISCOVERYF407VG (see ppcrossarm -i for other Discovery boards)

You should also refrain from using optimizations > -O1 as there are some issues with the compiler that make your compiled binary unusable.

I have built the crosscompiler and the rtl for the STM32F429xx controller. Basic functions seem to work.

By default, the rtl is compiled with optimization -O2. Should the rtl be better compiled with optimization -O1 too, if there are issues with the compiler? Or is the rtl not affected?

What is recommended by the developers? Where bug reports accepted, if I use optimization -O2?
