Add documentation ARM v8 Baseline and Mainline (Cortex-M23/M33/M35P)

Open NZSmartie opened this issue 4 years ago • 0 comments

I'm getting started with a ATSAML10xxxx series project that uses Cortex M23 (ARM v8 baseline)

Since I'm new to Rust development (but already an experienced embedded developer), I've been following The Embedded Rust Book - Installing the tools. Specifically it suggests adding the following targets with rustup target add

  • thumbv6m-none-eabi
  • thumbv7m-none-eabi
  • thumbv7em-none-eabi
  • thumbv7em-none-eabihf

As for ARM v8 baseline, mainline and mainline with extension, the targets are respectively:

  • thumbv8m.base-none-eabi (e.g. Cortex M23)
  • thumbv8m.main-none-eabi (Not sure which arch uses this instruction set specifically 🤷‍♀️)
  • thumbv8m.main-none-eabihf (e.g. Cortex M33, CortexM35P)

Could these be added to README.md and also other places I've yet to come across?

https://github.com/rust-embedded/cortex-m-quickstart/blob/ae6ad14ad45c2b83dd9820628f2e0cddc2c44e32/README.md#L17-L23 and https://github.com/rust-embedded/cortex-m-quickstart/blob/ae6ad14ad45c2b83dd9820628f2e0cddc2c44e32/README.md#L77-L84

Maybe a reference to the Cortex-M comparison table might help with picking out the right instruction set
