Dear，Jorgen：

Ths，The problem is solved. I found that the Bootloader folder will appear after power-on and will disappear after a while.

Do you see the removable device in bootloader mode? Did you try to reflash the interface MCU firmware? Does the board work with another computer? Is LED 5 blinking, and at what rate?

Dear，Jorgen：

I am sure that my USB cable is data lines and the Interface MCU enters Bootloader mode because the LEDs flash at the correct frequency. But my computer system can't recognize DK Device, win1064 bit, home version

Hi,

To reflash the interface MCU, simply drag and drop the BIN-file to the removable device named BOOTLOADER. If you do not see this device, please make sure you are using a USB cable with data lines (some cables are made for charging only, and will not work correctly).

Best regards,
Jørgen
