## Developer Guide
|
|
|
|
> [!TIP]
|
|
> You should use the pre-configured dev container in VSCode to ensure easy development.
|
|
|
|
Expected pre-requsites:
|
|
* [Docker](https://docs.docker.com/engine/install/) or [Podman](https://podman.io/docs/installation) container environment (for dev container support).
|
|
* [VSCode](https://code.visualstudio.com/download).
|
|
|
|
### A quick start video tutorial on how to set up your environment
|
|
[](http://www.youtube.com/watch?v=h05ufOsRgZU "Docker Devcontainer quick start guide").
|
|
|
|
### How to debug
|
|
Within the code, use the `debugf` command, and then deploy using a debug build e.g. `make run-debug`.
|
|
|
|
```c
|
|
debugf("joybus_rtc_detect_async: %s %s %s %s\n",
|
|
detected ? "detected" : "not detected",
|
|
status.stopped ? "stopped" : "running",
|
|
status.crystal_bad ? "crystal:BAD" : "crystal:OK",
|
|
status.battery_bad ? "battery:BAD" : "battery:OK"
|
|
);
|
|
```
|
|
The output will then be shown within the console.
|
|
|
|
For the future:
|
|
`ms-vscode.makefile-tools` will hopefully help (installed automatically in dev container).
|
|
NOTE: it does not yet work with `F5`: see [this blog post](https://devblogs.microsoft.com/cppblog/now-announcing-makefile-support-in-visual-studio-code/).
|

|
### How to deploy and/or debug to the SC64
|
|
Make sure that your firmware is compatible (currently v2.20.2+).
|
|
See: [here](https://github.com/Polprzewodnikowy/SummerCart64/blob/v2.20.2/docs/00_quick_startup_guide.md#firmware-backupupdate)
|
|
|
|
You will need to download a copy of the `sc64deployer` from [here](https://github.com/Polprzewodnikowy/SummerCart64/releases/download/v2.20.2/) or build your own depending on the scenario.
|
|
|
|
> [!TIP]
|
|
> Toggle the N64 POWER switch to load and run the ROM.
|
|
|
|
#### From within the devcontainer
|
|
##### To the native OS
|
|
It is not currently possible to directly communicate with USB devices from a devcontainer. BUT, you can use a proxy TCP/IP connection as a workaround.
|
|
To set up a "proxy", open a terminal window on the native OS, then `cd ./tools/sc64` and then `./sc64deployer.exe server`.
|
|
Keep this terminal window open.
|
|
|
|
Then, in the dev container, use `make run` or `make run-debug`.
|
|
|
|
##### To a remote LAN device
|
|
If you want to Deploy and debug to a fully remote target (over your LAN)
|
|
Make sure that the remote target device (i.e. the one with the carts USB connected) has the server running (similar as specified in To the native OS, but):
|
|
|
|
> [!TIP]
|
|
> Make sure you specify its accessible IP and port.
|
|
|
|
```
|
|
./sc64deployer server [THE_LAN_IP_ADDRESS]:9064
|
|
```
|
|
|
|
|
|
The following commands can then be run from the docker environment terminal:
|
|
|
|
To upload and run the ROM (requires power toggle):
|
|
```
|
|
REMOTE=[THE_LAN_IP_ADDRESS]:9064 make run
|
|
```
|
|
|
|
To debug the ROM (requires power toggle):
|
|
```
|
|
REMOTE=[THE_LAN_IP_ADDRESS]:9064 make run-debug
|
|
```
|
|
|
|
To debug the ROM with upload and auto reboot:
|
|
(note: the current debugging session menu may not be the same as the file uploaded. you need to `make all` first to ensure the latest menu is uploaded).
|
|
```
|
|
REMOTE=[THE_LAN_IP_ADDRESS]:9064 make run-debug-upload
|
|
```
|
|
|
|
#### Directly From your host (Windows) OS
|
|
* Download the deployer [here](https://github.com/Polprzewodnikowy/SummerCart64/releases/download/v2.20.2/sc64-deployer-windows-v2.20.2.zip).
|
|
* Extract and place `sc64deployer.exe` in the `tools/sc64` directory.
|
|
* Then use `make run` or `make run-debug` in the terminal.
|
|
|
|
|
|
#### To an SD Card
|
|
NOTE: A "release" version of the SC64 menu is called `sc64menu.n64` and can be generated by running `make all` or running `make sc64`. You can then copy the resulting `sc64menu.n64` file to your SD card.
|
|
|
|
|
|
### How to deploy and/or debug to other flashcarts/emulators
|
|
#### Ares Emulator
|
|
For ease of development and debugging, the N64FlashcartMenu ROM can run in the [Ares emulator](https://ares-emu.net/) (without most flashcart features).
|
|
|
|
* Ensure you have the Ares emulator on your computer.
|
|
* Load the `N64FlashcartMenu.n64` ROM.
|
|
|
|
#### Others
|
|
* Add the required file to the correct folder on your SD card.
|
|
|
|
|
|
### How to add debug code
|
|
Within the code, use the `debugf` command, and then deploy using a debug build e.g. `make run-debug`.
|
|
|
|
```c
|
|
debugf("joybus_rtc_detect_async: %s %s %s %s\n",
|
|
detected ? "detected" : "not detected",
|
|
status.stopped ? "stopped" : "running",
|
|
status.crystal_bad ? "crystal:BAD" : "crystal:OK",
|
|
status.battery_bad ? "battery:BAD" : "battery:OK"
|
|
);
|
|
```
|
|
The output will then be shown within the terminal.
|
|
|
|
### Using feature flags
|
|
To enable features that are not build by default, you can input flags as part of the build.
|
|
i.e. the current notible flags are:
|
|
```
|
|
FEATURE_AUTOLOAD_ROM_ENABLED
|
|
FEATURE_PATCHER_GUI_ENABLED
|
|
BETA_SETTINGS
|
|
FEATURE_DEPRECATED_FUNCTIONALITY
|
|
```
|
|
An example build command would be:
|
|
`make clean && FLAGS="-DFEATURE_PATCHER_GUI_ENABLED -DFEATURE_DEPRECATED_FUNCTIONALITY" make all`
|
|
|
|
|
|
### Update submodules
|
|
To update to the latest version, use `git submodule update --remote` from the terminal.
|
|
|
|
#### libdragon
|
|
This repo currently uses the `preview` branch as a submodule at a specific commit.
|
|
* To ensure your local instance is building against it, use `cd ./libdragon && make clobber -j && make libdragon tools -j && make install tools-install -j && cd ..`
|
|
|
|
### Generate documentation
|
|
Run `doxygen` from the dev container terminal. Make sure you fix the warnings before creating a PR!
|
|
Generated documentation is located in the `output/docs` folder and auto-published to the `gh-pages` branch when merged with `main`.
|
|
|
|
Once merged, they can be viewed [here](https://polprzewodnikowy.github.io/N64FlashcartMenu/).
|
|
|
|
#### Test generated docs in the dev-container
|
|
Testing the documentation locally allows you to preview changes and ensure everything renders correctly before submitting your changes.
|
