Cora Z7-10 is not detected by VIVADO2018.12 and PC

[spesyvyi]

I have bought Cora Z7-10 and installed Vivavdo and board files. Everything worked great, I was able to modify IO example with LEDs (programming with  usb JTAG). But after few days, during the new bitstream programming there was some error and Cora Z7 has disappeared from the Hardware Manager. When trying to Autoconnect, the board is not detected. In Windows Device Manager there is also nothing. RX and TX LEDs , LD7, LD6 on the board are ON all the time, so I am afraid the whole  board is broken now. Is it possible to do something with this?

Hi @spesyvyi,

Are you able to see the Cora Z7-10 in Adept 2 here? Have you tried using a different PC or  USB cable?

thank you,

Hi, @jpeyron

It is not seen in Adept.  When connecting to another PC all LEDs behave the same (TX, RX are ON), as well as with other USB cable. I have also tried to power it with 5V adapter (with  replaced jumper), again all LEDs (TX, RX, LD7, LD6) are ON.

Hi ,

Please re-install the FTDI drivers here.

thank you,

Thank you for the advice, I reinstalled it as written in the instruction. It did not help. The problem is that windows does not see the connected board as any device, I am afraid that this could be a hardware problem.

Hi @spesyvyi,

We have reached out to another engineer about this to see what their thoughts are.

Thank you,
