Eval board, STEVAL-25R3916B for ST25R3916B chip

[biotillion]

Hi,

This is my first post in the ST Community.  

We bought an evaluation board for the 25R3916B reader chip. It successfully reads tags when working on its own as we can clearly see on the local eval board display. We also downloaded the latest PC software from the ST website and the software successfully runs on a PC.

We cannot, however, get the eval board to talk to the PC in any way, form or fashion. Does anyone have any idea what might be wrong?

Hi,

just press the blue user button (4) and keep it pressed while pressing the reset button (3). See buttons location on figure 3 in UM3033 Getting started with the STEVAL-ST25R3916B. Once in USB mode, it should be displayed "USB mode" on the LCD..

Thanks BT,

I forgot to mention that we could get the eval board to be in the USB mode without issue.  The PC software, however does not see the eval board at all.  We had 3 senior engineers working on this for a while and could not get the PC software to recognize the eval boarding any way.  We tried this on 3 PCs. We are obviously missing something. 

Thanks, 

Hanan

Hi,

there are 2 USB connectors on the board, one is dedicated to the STLink and the second one to the communication with the GUI. make sure to use the "MCU USB" not the STLink USB".
