Building instructions

Requirements

• OSS CAD Suite (FPGA core)
  • Requires a modified version of icepack, see below for more information
• Wonderful Toolchain (IPL1, recovery, updater)
• CMake (MCU firmware)
• NASM (IPL0)
• Nim 2.0+ (FPGA core, IPL0)
• Ninja (MCU firmware)
• Python 3.x (SPI images, updater)
  • • crc library
• dd, dosfstools, mtools (emulator images)

icepack

For the FPGA to be ready in time, the bitstream needs to be loaded at the highest speed possible. I created a PR for icepack which adds a setting to change this. Without it is not possible to compile the FPGA bitstream.

Compiling

1. Make sure to fetch the Git submodules: git submodule update --init --recursive.
2. Run make help to read what build options are possible.
3. Run make (or make ...) to build the requested components.
