Board & reproducibility method
Establish a known-good programming baseline.
STMicroelectronics NUCLEO-G431RB uses its own board, serial or programming tools. Header7F’s reproducibility method helps preserve the firmware, wiring and exact stimulus around a failure.
- Check the target voltage, pinout, firmware and supported programming software. Confirm a small known-good board example first.
- Record the source revision, tool version, wiring and exact command or input that reproduces the symptom.
- Apply Header7F’s run-manifest approach to keep the logs, setup and failing case together; if your design includes AXI logic, use its separate handshake guides.
Header7F does not connect to USB/UART, flash firmware, debug JTAG/SWD or decode SPI/I2C. Its protocol examples apply only to the interfaces they describe.
