Nexys A7: target device not detected by Vivao Hadware Manager

[luca-c]

Dear experts,

I'm getting started with a Nexys A7 board and I'm trying to set up the firmware programming via the USB-JTAG interface using Vivado 2019.2 running on CentOS 7.

When I open the hardware manager and try to add a new target, I simply don't see the board in the available targets, and upon trying to auto connect there is a warning "No hardware target exist on the server [localhost:3121]"

I checked the position of the jumper JP1, and tried a couple of different cables without any change.
I do see the device connected with lsusb [1], and it looks like it is recognized by the system when I plug the cable (the output of dmesg is below [2], though I am unsure if the last line "device disconnected" relates to the problem).

Other ways to load the fw (from a USB stick and from the Quad SPI) just work fine, but I'd like to have also the USB-JTAG working.

Could it be a simple problem of configuration, or some step that I have overlooked?

Thank you very much in advance for your help!
Luca
