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.
