Notice

To ensure successful STM32 flashing, please note the following:

• The USB port on some computers may cause unstable flashing due to driver or signal compatibility issues. It is recommended to try a different USB port for connection.
• If changing ports does not work, an effective solution is to connect via an external USB hub, which often improves compatibility.
• When the flashing software reports the error shown below, please also prioritize trying a USB hub. If the issue persists, check or use the host computer for flashing.
