There was a problem hiding this comment.
since core::error::Error is now stable it might make sense to impl it here? since you already have impl core::fmt::Display this should be straight-forward?

CI failed because the ubuntu-latest label migrated to ubuntu 24.04 (https://github.blog/changelog/2024-09-25-actions-new-images-and-ubuntu-latest-changes/), and it looks like there the qemu package is no longer available. A quick fix would be to change the runner image to Alternatively, CI could use |
That was easier than I had expected: #562 |

This PR ports some of the ongoing work in the RISC-V ecosystem to Cortex-M targets. Namely, I adapted the
riscv-paccrate to the newcortex-m-paccrate.The main purpose of this crate is to isolate fundamental traits and data types from potential breaking changes in
cortex-m. Namely, it currently contains traits for enumerating exceptions, interrupts, priorities, and core IDs. It also provides a basic fallible function support for Cortex-M devices, with an error enum with some of the most typical issues developers may face.Related PRs in RISC-V: #222 and #223
Related PRs in Cortex-M: #488
Once this is merged, I plan to continue porting new functionalities from RISC-V to Cortex-M (e.g., new syntax for interrupt and exception macros)
