main

✓ from stm32loader import main

✗ import stm32loader

stm32loader exposes a CLI entry point, not a module with classes. Use the main function for programmatic access.

Flash firmware via USART using main() with CLI arguments as list.

from stm32loader import main # Example: flash firmware.bin to STM32 via USART at /dev/ttyUSB0, baud 115200 # Equivalent CLI: python -m stm32loader -p /dev/ttyUSB0 -b 115200 -e -w -v firmware.bin main(['-p', '/dev/ttyUSB0', '-b', '115200', '-e', '-w', '-v', 'firmware.bin'])

Debug

Known issues

breakingVersion 0.6.x and earlier used different argument parsing. The '-p' flag for port changed behavior.

fix

Use version >=0.7.0. Check CHANGELOG for API changes.

affects: <0.7.0

gotchaThe library is designed for CLI use; programmatic usage via main() replicates the CLI. Do not attempt to import internal modules.

fix

Use from stm32loader import main and pass sys.argv or a list of arguments.

affects: all

gotchaDFU mode requires additional system tools (e.g., dfu-util) and is not fully implemented in this library.

fix

For DFU, use dfu-util directly. This library focuses on USART bootloader.

affects: all

Errors

Common errors & fixes

ImportError: No module named stm32loader

stm32loader is not installed, or you are using a Python environment without it.

fix

Run: pip install stm32loader

Error: Unable to open serial port /dev/ttyUSB0

Port not found or permission denied (Linux).

fix

Check port exists (ls /dev/ttyUSB*). Add user to dialout group or use sudo.
