A work-in-progress multiplayer arcade game that runs directly on the Raspberry Pi 3 B+ hardware, written entirely in Zig.
"Hello World" OS using the MiniUART.
Tested and working on real hardware.
It has regressed on real hardware, and I haven't fixed it yet.
zig build qemu
Debugging with GDB
zig build qemu -Dgdb
In another terminal:
gdb zig-cache/clashos-dbg -ex 'target remote localhost:1234'
Sending a New Kernel Image via Serial
While the Raspberry Pi is running, you can use
zig build upload -Dtty=/dev/ttyUSB0
If using QEMU, use
zig build qemu -Dpty and note the tty path.
In another terminal window,
cat the tty path.
In yet another terminal window, you can use the
zig build upload
command above, with the tty path provided by QEMU.
This is compatible with using GDB with QEMU, just make sure to pass
-Dgdb to both
zig build commands.
- Mount an sdcard with a single FAT32 partition.
For further changes repeat steps 3 and 4.
- Interface with the file system
- Get rid of dependency on binutils objcopy
- Interface with the video driver
- Get a simple joystick and button and use GPIO
- Sound (should it be the analog or over HDMI)?
- Make the game
- Build arcade cabinets

How to view the serial data
/dev/ttyUSB0 is the device that represents the serial-to-USB cable:
sudo screen /dev/ttyUSB0 115200 cs8
