Appendix A: ARM64 reference

This appendix is a “cheat-sheet” reference, not a tutorial. We recommend that you consult the plentiful online materials and your favorite AI (or ask course staff!) to figure out questions about ARM64 that go beyond what’s described here.

Appendix B: Hardware Manuals

Appendix B: Reading the hardware manuals

You will need two kinds of documentation.

1. The Raspberry Pi peripheral manual, “BCM2835 ARM Peripherals”. This is the authoritative source for the device registers you program in Quest 2.

Appendix C: Testing & Debugging

Note: Kernel and bare-metal programming is unforgiving: a single wrong address can hang or silently corrupt the emulated machine with no error message. Start early, build and test in the small increments suggested in each task’s Hints, and lean on gdb. When you’re stuck, the first question to ask is almost always “what address is this, and what does the manual say lives there?”
