Precursor + Renode Precursor is an FPGA-based dev platform for secured applications. The reference design runs a VexRiscv CPU core plus a wide range of peripherals. Developing software for an embedded target can be a challenge in the best of circumstances, and when you’re starting out there is no display, no keyboard, not even a serial port – you might have a blinking LED and a few pads you can probe with an oscilloscope.
