Building the Firmware

Releases

The release tarballs contain pre-built firmware, emulators for windows and *nixes, documentation, and examples/demos of BASIC, C, and assembly programs. - Release archives

Compilation

Sources

Note that to build the firmware, additional third-party sources are required. If not supplied, these will be downloaded automatically at build-time. These are not needed to build the emulators however. The automatic downloads, and the 'git' dependency may be avoided by collecting these sources manually.

Then explode the tarballs and set the following variables in the environment:

$ export PICO_SDK_FETCH_FROM_GIT=OFF
$ export PICO_SDK_PATH=/path/to/picosdk_sources
$ export PICO_TINYUSB_PATH=/path/to/tinyusb_sources
$ export PICO_DVI_PATH=/path/to/picodvi_sources
$ export PICO_FATFS_PATH=/path/to/picofatfs_sources

Dependencies

  • 'build-essential', 'base-devel', or equivalent (GCC for *nix binaries)
  • 'x86_64-w64-mingw32-g++' or equivalent (GCC for windows binaries)
  • 'gcc-arm-none-eabi' (GCC for ARM binaries)
  • 'arm-none-eabi-newlib' (C stdlibs for bare-metal ARM target),
  • 64tass (6502 assembler)
  • 'cmake'
  • SDL2 development library
  • 'python3'
    • 'pillow'
    • 'gitpython'
    • 'pyserial' (optional for uploading files via serial port, not needed to build)

All of the sources and dependencies are freely available. Most distros have the dependencies packaged.

  • Arch-based distros:
    NOTE: '64tass' is in the AUR (https://aur.archlinux.org/packages/64tass).
