An experiment in bare-metal programming using the Zig programming language on Raspberry Pi 3B+.
Untested on real hardware.
To build (tested with Zig 0.9.0):
$ zig build
To run it in QEMU, you will need a compiled device tree (dtb) for the Raspberry
Pi 3B+. One can be obtained from the Linux kernel source by running make ARCH=arm dtbs and having a look in arch/arm/boot/dts.
Then, run it, supplying the device tree:
$ qemu-system-aarch64 -M raspi3b -kernel zig-out/bin/kernel8.img -dtb bcm2837-rpi-3-b-plus.dtb
