Longan Nano: Can't install dfu, what are the Zadig usb configuration parameters?

I am using Win7 64 bit.



I am trying to run the blink.cpp example for the Sipeed Longan Nano and am stuck on step 6:

6. Install drivers using Zadig

PIO has a built-in dfu-util download tool. To use this tool, you need to install the libusb driver for the development board. (Note: different from GD official driver)

It is recommended to install the winusb driver via Zadig. download link



The “GD32 device in dfu mode” does not appear in the Zadig drop down list.

The Longan nano board does not appear as a USB device in Windows device manager.

Zadig has a work around if a preset device config file can be created but I don’t know the VID, PID, and MI parameters.



Need help getting past this point.

Hi There

mabey you should click Options -> List All Devices ,as below :smiley:

Did you try to press BOOT0 and keep while for short time pres RESET?



I miss this step and no device was visible in device manager in WIN10.



I found this trick, but I moved to another computer with Ubuntu, compile blink and program with dfu-util.



But no blinking was visible. Now I back to Windows computer and Unknow device is visible in Win Device Manager



Zadig software still don’t see the board on the list

Well, it is 11 months later and I am having the same problem. Zadig doesn’t see the device. This is under Window 10 Pro. When I do the boot reset sequence I get an unknown device showing up under device manager and a couple of new entries in Zadig, but they are not “GD32 Device in DFU mode”. I have read of a couple of people who fixed their machine, but it was a load of work with tools I don’t have. Surely someone has fixed this by now, or is everyone just giving up and using linux?

One other thing, when I went to download the USB DFU tool as in step six of getting to blinky, I got a json message saying that it was a big file, but no download.

Hi,
i would like to debug over USB (DFU). How can I make it in Eclipse or Nuclei Studio IDE?

many greetings
