Common problems of the STM32F407 discovery board (STM32F407ZGT6)

1.Can’t find the USB to serial port.

There may be several reasons for this problem:

1)The discovery board is not powered.

   In this case, please check whether the blue power light in the lower right corner of the discovery board is on, if not, press the power switch. The power indicator must be on for the computer to find the USB to serial port. In addition, the STM32F407 discovery board (STM32F407ZGT6) does not support JLINK power supply, and it is not recommended that you use ST LINK to power the STM32F407 discovery board (STM32F407ZGT6).

Q1.1

2) The wrong USB port is inserted.

   To use USB to serial port, the USB cable must be plugged into the USB_232 interface in the lower left corner of the STM32F407 discovery board (STM32F407ZGT6). As shown in Figure Q1.1:

3) The USB driver is not installed.   

Please install the CH340G driver. The CH340 driver is in the CD data: 6, software data\software\CH340 driver (uSB serial port driver)_XP_WIN7 shared folder.

2. flymcu cannot download the code.

Common reasons are as follows:

 1) The DTR and RTS settings of the flymcu software are wrong.      

   The correct setting is: the low level of DTR resets, the high level of RTS enters the BootLoader, as shown in Figure Q2.1: 

As shown in the figure: do not check: use Ramlsp, do not check: write option bytes when programming to FLASH, DTR, RTS should not be set incorrectly, the serial port number should be selected correctly, and the maximum baud rate cannot exceed 76800.

2) The serial port is wrong.   

   This must be checked, which is the USB to serial port of your discovery board. In the device manager, you can check the type of USB to serial port, as shown in Figure Q2.2:

Q2.2

As shown in the figure, you can see that the computer has a total of 2 COM ports, and obviously we can know that the USB to serial port of the STM32F407 discovery board (STM32F407ZGT6) is COM3. Because the STM32F407 discovery board (STM32F407ZGT6) is a USB to serial port, it must be USB-SERIAL, and the CH340G chip is used, so it must be COM3.

Special attention: your computer is not necessarily COM3, but the string of USB-SERIAL CH340 must be the same, please choose according to the specific situation!
