arm64-baremetal-course

A repo to setup a working environment for experimentation

The code provided as part of this repository is ONLY for learning purposes!

TODO: Add course link

Instructions

1. Create a code space (reuse if already created):
   1. code -> codespaces -> + button!
   2. Wait for codespaces to initialize fully (might take 2-3 minutes)
   3. You should see a working vscode code environment
   4. Don't worry about the dependencies. Toolchains, headers, build-essentials, QEMU environment setup everything is setup for you :)
2. Compile the bare-metal kernel for Raspberry Pi-3b for a particular assignment/lab-exercise:
   1. Create a new folder e.g. cd sample-assignment
   2. Create necessary files and copy over the source code from the files attached in the course's assignment/lecture sections
   3. Once all the files are copied, your directory structure should contain -
      1. Source - .c / .S files
      2. Headers - .h files
      3. Makefile - Makefile
      4. Linker Script linker.ld
   4. Run make to compile the kernel (You should see kernel8.img file being generated)
3. Run the generated image on QEMU
   1. qemu-system-aarch64 -M raspi3b -kernel kernel8.img -serial null -serial stdio
   2. Ctrl + c to quit QEMU
