HID Flash

supported in English and Chinese

Enter the HID bootloader method:

1. Hold down the <KEY>, power on or reset again, and the C13 LED will blink to release
2. APP enters the bootloader reference stm32f401_test_APP 0x8004000.zip project
3. More instructions

How to enter ISP mode

• Method 1: When the power is on, press the BOOT0 key and the reset key, then release the reset key, and release the BOOT0 key after 0.5 seconds
• Method 2: When the power is off, hold down the BOOT0 key, and release the BOOT0 at 0.5s after the power is on
• DFU Mode: Use the data line to connect to the computer. If there is an unrecognized problem, you can heat the chip appropriately (25°C) and then re-enter the ISP mode
• Serial Port Mode: Connect PA9 and PA10 of core board with USB serial port
• Soft: STM32CubeProg。
