What is the minimum RAM-Size to run linux? It depends on how much tuning you're ready to make. Without doing a lot of tuning, I would say 8 MB of RAM is really the minimum. And indeed the STM32F4/STM32F7 platforms that can run Linux have 8 or 16 MB of external RAM: https://elinux.org/STM32#STM32F4_based. > 2.)
