Agenda

• Announcements
  • alloc-cortex-m 0.4.3 released
  • svd2rust 0.27.2 released
  • riscv-rt 0.10.0 released
  • cortex-a crate renamed aarch64-cpu and released at v9.0
• cortex-m-interrupt now with const registration and M:N interrupt:driver connections, feedback welcome
  • https://github.com/datdenkikniet/cortex-m-interrupt/blob/const-approach/cortex-m-interrupt-examples/examples/register_interrupt.rs
• critical-section on msp430 bloat:
  • can be worked-around by putting the msp430 impl inside the c-s crate and removing the 'extern rust' calls
    • https://github.com/rust-embedded/critical-section/compare/main…cr1901:msp430-cs:msp430-cs
    • But it's not clear yet how to fix this longer-term, it seems like most likely a bug in LLVM or Rust's inliner
