Notice

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

  • Some computers' USB ports may cause unstable flashing due to driver or signal compatibility issues. We recommend that you try connecting using a different USB port.
  • If changing ports doesn't help, an effective solution is to connect via an external USB hub, which often improves compatibility.
  • When the flashing software displays the error message below, try using a hub first. If the problem persists, please check or use the host computer to flash
