BL Firmware

tip

Please note that the bootloader has already been pre-flashed at the factory, no need to re-flash

Enter Flash Mode

There are two ways to enter flash mode
Method 1: With the tool board completely powered off, press and hold the BOOT button, then connect one end of a TYPE-C cable that supports data transfer to the main board and the other end to your device
Method 2: After connecting one end of a TYPE-C cable that supports data transfer to the main board and the other end to your device, press and hold the BOOT button, then press the RST button, release the RST button first, and finally release the BOOT button

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
