Commands#

Use the commands below to install the targets you need.

# M0/M0+ core; common chips: STM32F0xx, PY32F0xx, ...
rustup target add thumbv6m-none-eabi

# M3 core; common chips: STM32F1xx, ...
rustup target add thumbv7m-none-eabi

# M4 and M7 cores; common chips: STM32F4xx, ...
rustup target add thumbv7em-none-eabi

# M4F and M7F cores; F means hardware floating point. Common chips: STM32F4xx, STM32G4xx, STM32H7xx, ...
rustup target add thumbv7em-none-eabihf

# M33F core; common chips: STM32U5xx, ...
rustup target add thumbv8m.main-none-eabihf

Summary#

Every chip covered by this site uses one of the target values listed above. Installing all of them is convenient.

Troubleshooting#

• If compilation reports can't find crate for core, the chip's target is usually missing.
• If you are unsure which core a chip uses, check its datasheet and select the matching target.
• Prefer an eabihf target for hardware floating-point chips. A mismatch between the project and chip can fail at build or run time.
