ST25R3916 discovery board, DFU not found GUI problem "not working"

[ADSB]

Dear ST Community,

I hope you are doing great.

I am having a trouble to run the GUI of ST25R3916 discovery board on my machine, I have windows 10 operating system, I tried to reinstall the included drivers (with the GUI), but the GUI is not able to recognize that the reader is connected to my PC. In the device manager when I connect the board I am getting the following drivers in my list:

• Universal Serial Bus Devices --> ST-link debug
• Ports (COM and LPT) --> STMicroelectronics STLink Virtual COM Port

Also I have used dfu-util to check if my system can identify the DFU, but It can not. I tried different PCs, but all have windows 10 OS. I am getting the same problem in all of them.

I would really appreciate your help.

Thank you very much.

Hi,

you need to connect the micro-USB plug and press the User button while powering. Only then it enters USB mode. This is also described in the user manual.

Thank you very much,

this worked out.

I just wanted to mention that it is not clear in the user manual that the user button has to be pressed.

Many thanks again for your help.

Hi to all,

i have a similar problem: i want to connect the STEVAL-25R3916B  to the discovery gui but, but this doesn't find /recognise the eval board.

I connect the mini-USB , and during the power on , i press the user button and the display shows me that the board is in USB mode. Then i launch the SW but it isn't connected to the eval..

In the device manager i find only a virtual com STlink, no more... is it enought?

i just already try to use micro-USB, mini-USB, then also togheter, changing the JA settings but without any good results

please help me 

thanks

Hey,

Got the same error (ST-Link detected instead of STM device on DFU mode) and still can't get any solution on my 2 day researchs.

Is there someone who know how to resolve this issue ?

@logantenna do you have the solution now ?

Oh and I tried using the ST-link utility to make some test but I'm still not able to switch of device mode 
And yes I am only connected with the USB port and the board's screen show the USB mode

Thanks,

Antoine, for Kuvee
