Running tests on native

cargo test

The ARM assembly is replaced with an equivalent Rust implementation on non-ARM targets, so the same tests run on any host machine.

Running tests on embedded (QEMU)

Install the Rust targets:

rustup target add thumbv7m-none-eabi thumbv8m.main-none-eabi

Build and run for each supported core:

Cortex-M3

cargo build -p demo-cortex-m3 --target thumbv7m-none-eabi
qemu-system-arm \
  -machine mps2-an385 \
  -cpu cortex-m3 \
  -nographic \
  -semihosting-config enable=on,target=native \
  -kernel target/thumbv7m-none-eabi/debug/cortex-m3-tests

Cortex-M33

cargo build -p demo-cortex-m33 --target thumbv8m.main-none-eabi
qemu-system-arm \
  -machine mps2-an521 \
  -cpu cortex-m33 \
  -nographic \
  -semihosting-config enable=on,target=native \
  -kernel target/thumbv8m.main-none-eabi/debug/cortex-m33-tests

Each test name is printed via semihosting and QEMU exits with success after all tests pass.

Running benchmarks on embedded (QEMU)

Replace the binary name with the -bench variant, e.g. for Cortex-M33:

cargo build -p demo-cortex-m33 --target thumbv8m.main-none-eabi
qemu-system-arm \
  -machine mps2-an521 \
  -cpu cortex-m33 \
  -nographic \
  -semihosting-config enable=on,target=native \
  -kernel target/thumbv8m.main-none-eabi/debug/cortex-m33-bench

Running on STM32H573I-DK

Requires probe-rs. Build and flash from the runtime/stm32h573i-dk directory:

cd runtime/stm32h573i-dk

Tests

cargo build --bin stm32h573i-dk-tests
probe-rs run --chip STM32H573IIKx ../../target/thumbv8m.main-none-eabi/debug/stm32h573i-dk-tests

Benchmarks

cargo build --bin stm32h573i-dk-bench
probe-rs run --chip STM32H573IIKx ../../target/thumbv8m.main-none-eabi/debug/stm32h573i-dk-bench

Output is printed over RTT. probe-rs run flashes the binary and attaches to RTT automatically.
