Tomek, as I clarified, porting NuttX to a FPGA will require a soft-core CPU. I don't envision an opertaing system without a CPU, I see that like a bad design choice if possible at all Using a soft core and custom peripherals seems more valuable, even including video output and USB host for mouse/keyboard handling. I've done that for Micropython
