I found that, even using the STM32 IDE and HAL/CMSIS, I needed to deep dive into the hardware documents, compiler section attributes and linker scripts to build what I wanted (a digital graphic equaliser with optical I/O and a display/control screen on a Nucleo-H753ZI board). DMA and cacheing don't mix! That was my first adventure in ARMland but the experience helped a lot for subsequent hacking on RP24040/2350 kit.
