ST25R3916 discovery board, DFU not found and ST-link showed on device manager

Hey,

I started using the ST25R3916 discovery board and I have this error:
a ST-Link is detected instead of an "STM device on DFU mode"

I tried using the ST-link utility to make some test but I'm still not able to switch of device mode 
Now I am only connected with the USB port and the board's screen show the USB mode, only my PC doesn't recognise it correctly.

Is there someone who know how to resolve this issue ?


Thanks,

Antoine, from Kuvee

Hi Antoine,

no idea, whatsoever. It is also the first time hearing that it does not work at all. 

Maybe an issue with the device detection in Windows such that the GUI does not get notified.... You could try first connecting the board and then open the GUI - AFAIK on startup of the GUI it will always try to connect. 

BR, Ulysses

Hey Peter,

 

Thanks for replying
Unfortunately I don't have this issue so it doesn't help me.
My board is not telling me to fix my firmware as I already updated it and it perfectly show me that it is in USB mode, but my PC can't find it.
In USB mode there is no device detected, but in ST-link mode it is perfectly detected.

Hi Antoine,

you need to plug the micro-USB to have PC comm mode operational!

Only it goes to STM32L4. The mini-USB just connects the ST-Linkv2.
