  • Framework Laptop feature requests – RISC-V Mainboard

    I'd also vote for an FPGA Mainboard, ideally Lattice, ideally iCE40, and ideally compatible with Project IceStorm (Yosys, Arachne-pnr, and IceStorm) open source tools:

    Think something similar to MiSTer FPGA -- but in a laptop form factor, and able to run all sorts of "soft" CPUs, i.e.:

    As others have already mentioned the Lattice ice40 family is supported by OSS chains through project icestorm [0].

    There were some nice boards floating around though you may have to watch out for supply chain issues still plaguing this market. Examples:

    - icoboard: has the 8k LUTs chip, comes with soldered PMODs[1], if you get it watch out as you either need a RaspberryPI with GPIOs soldered to program it, or you purchase their USB FTDI interface in addition. See: http://icoboard.org/

    - iCEBreaker, comes with the 5k LUTs chip, has the USB-FTDI interface built-in, but you need to solder the PMODs yourself. See: https://www.crowdsupply.com/1bitsquared/icebreaker-fpga#prod...

  • Thoughts on OSFPGA?

    You know the best part about Lattice FPGAs? The iCE40 bitstream has been reverse-engineered. As a result, you can delete Diamond and use a completely open-source toolchain instead. It's so much cleaner, easier, and less bloated that it just shows how awful all the vendor tools have gotten.

  • J2 open processor: an open source processor using the SuperH ISA

    >The rest of this page explains how to compile and install a "bitstream" file to implement this processor in a cheap (about $50) FPGA board, then how to build Linux for that board and boot it to a shell prompt.

    >Numato: The cheapest usable FPGA development board ($50 US) the j2 build system currently targets is the Numato Mimas v2 (also available on amazon). It contains a Xlinux "Spartan 6" LX9 FPGA that can run a J2 at 50mhz, 64 megs of SDRAM, USB2 mini-B, and a micro-sd card slot.

    Nice!

    But, it would be an additional serious "would be nice" -- if this could run on Lattice FPGA's / IceStorm Open Source Toolchain:
