Hi, this book is great, but I have an Apple Silicon (M1) computer and brew install gdb fails with:

$ brew install gdb
gdb: The x86_64 architecture is required for this software.
Error: gdb: An unsatisfied requirement failed this build

It seems that gdb is just not supported on Apple Silicon computers.

I'm new to gdb, lldb, and debuggers. It'd be cool if the QEMU chapter showed how to use lldb to debug embedded Rust apps. Thank you!

I'm not sure how it works under the hood, but QEMU and hardware debugging works if you use VS Code + cortex-m-quickstart + these instructions:

Using arm-none-eabi-gdb instead of gdb works for me. It's installed with arm-none-eabi-gcc. See https://docs.rust-embedded.org/book/intro/install/macos.html
