My new Cora Z7 seems not working. What I must do?

[jfm]

To @Jcolvin I try to run the example 1 (blinking led) on my Cora Z7S board but the last step Harware Manager does not recognize the board. 

I use Windows 10 Pro  , a USB connexion from my laptop to the board, and Vivado 2023.2 software.

I restarted Vivado but no result. 

It seems that the problem exists for many Digilent Zynq boards . At least  @Martin2000 solved this same problem for a Basys 3 board, by reprogramming the chip FTDI  (on the board). So I suppose I must do the same ? But how can I do this ? 

Thanks to Jcolvin for his help.
