BL Firmware

Tip
  • Note that the factory has pre-flashed the bootloader, so no need to flash again.

Entering Flash Mode​

  • There are two methods to enter flash mode
  • Method 1: With the toolboard completely powered off, press and hold the BOOT button, then connect one end of a TYPE-C cable with data transmission to the mainboard and the other end to your device.
  • Method 2: After connecting one end of a TYPE-C cable with data transmission to the mainboard and the other end to your device, press and hold the BOOT button, then press the RST button, release the RST button, and finally release the BOOT button.

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.
