Schematics of Cora Z7

[thoonky]

Hello there, I do not seem to find the USB for UART/JTAG together with FTDI chip in the schematics for Cora Z7. Can someone share that?

The link pdf that I got is

Hi @thoonky,

Digilent has made the choice not share this page of the schematic for our boards.

Thanks,

OK.. do I need something special? my board does not seem to be able to be detected on the PCB USB bus.  

I tried on my PC and a Raspberry pi.

Hi @thoonky,

I don't know what operating system you are using on your PC, but you can look to see if the board is detected on a Windows system by seeing if the COM port and the USB Serial Converter A and USB Serial Converter B show up in the Device Manager (under COM Ports and Universal Serial Bus controllers, respectively). On Linux, you can use lsusb to see if the board shows up; I also know for Vivado installations on Linux based OS's that you will need to manually download the cable drivers separately. I am not sure about how a Raspberry Pi would detect the board. There are some additional images on how this would look on a Windows system here: https://forum.digilentinc.com/topic/21713-brand-new-basys-3-user-cant-get-vivado-to-see-it/#comment-62685. You can also see if the lightweight Digilent Adept System, https://digilent.com/reference/software/adept/start, properly detects the Cora Z7.

If you haven't already, it may also be a good idea to test a different USB cable; not all cables are set up to do data communication.

Let me know if you have any questions.

Thanks,
JColvin

Thanks JColvin.  I got it resolved.  Somehow most of my micro USB cables do not have the data lines (more of power charging).  I found 1 in the end it is working.
