Kos_Legacy_Codespace

Simple repo to launch Kos with legacy toolchain in Codespaces

To launch it from github, just click on the "<> Code" button, then "Codespaces" - "Create codespace on main".

Notes for KallistiOS:

  • kos: the latest version has been downloaded and compiled.
    • To go to the kos folder:
      • cd /opt/toolchains/dc
    • To compile a kos example, eg the hello example:
      • source /opt/toolchains/dc/kos/environ.sh
      • cd /opt/toolchains/dc/kos/examples/dreamcast/hello
      • make
  • kos-ports: the latest version has been downloaded, but needs compiling - this takes 3-4 minutes:
    • cd /opt/toolchains/dc/kos-ports/utils
    • source /opt/toolchains/dc/kos/environ.sh
    • ./build-all.sh
  • dc-tool-ip: the latest version has been downloaded and compiled.
    • By default, Codespaces can only access your Dreamcast's Broadband Adapter (BBA) if it is reachable via the internet (ie, addresses like 192.168.0.xxx, 192.168.1.xxx or 10.0.0.xxx, ... are not reachable)
    • If you want Codespaces to be able to access the BBA when it is only reachable via your internal network, check this link
    • to send an .elf executable to a BBA:
      • dc-tool-ip -t 1.2.3.4 -x hello.elf
      • (with 1.2.3.4 being the ip address of your BBA)

Tips:

  • Helper commands to launch in the Terminal (inside your codespace: File-View-Terminal):
    • To add the Kos examples to your VSCode workspace:
      • code -a /opt/toolchains/dc/kos/examples
  • When you have finished working with your codespace, click on the green "Code" button again, and on the 3 dots next to your codespace to stop your container from running. This will save you some free execution minutes (default idle timeout is 30 minutes, and you get 120 free core hours per month).
  • When launching your codespace for a 2nd time, be sure to do a git pull at the start inside your codespace to be in line with your repo, it will save you some problems.

If you want to use Codespaces in your own github repository

  • Copy the contents of the ".devcontainer" folder into your repo:
    • at least the "devcontainer.json" file,
    • and if you want to add extra stuff to a pre-built Docker image, also add the Dockerfile.
