Flashing the Firmware​

Important Notice

To ensure successful STM32 flashing, please pay attention to the following:

  • Some computer USB ports may have driver or signal compatibility issues, leading to unstable flashing. It is recommended that you try connecting to a different USB port.
  • 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 message shown below, also try using a hub first. If the problem persists, please check or use the host computer software for flashing.
