A $15 ColorLight ECP5 board, a LiteX SoC with Ethernet, and a cheap relay module: remote power-on/off for an office PC during COVID, built with the fully open-source Yosys/NextPnr toolchain. With a note on reversing boards from the FPGA side.
JavaScript running bare-metal on a RISC-V softcore inside a LiteX SoC, with framebuffer demos and a live browser editor served straight from the FPGA. No host, no transpilation.
LiteX was always command-line and text first, for cost reasons. It turns out that’s exactly what an AI agent needs to drive an FPGA. Here’s the methodology we use now, with LiteNVMe and M2SDR as real examples.
