Adept loses connection to devices

[Leon.k]

Hello.

My project includes cmod-s7 and HS3 connected to the XC7A35T.

I work on windows 10.

Everything worked correctly, but sometimes the system lost connection to the devices.

Reinstalling the Digilent drivers helped.

The last time (today), this happened, and the reinstallation had no effect.

These devices appear in the device manager, but Adept2 does not detect them.

Replacing USB cables is also not effective.

Any help would be greatly appreciated.

After several times re-installation with full erasing the Digilent folder it started to work again.

I afraid that it can happen on the customer site.

Please check the issue and fix the problem.

Hi@Leon.k,

I apologize for the long delay.

I presume that the XC7A35T is the Arty A7 board that you mentioned in your otherthread? When you mention that the boards are not detected, are you referring to just the Cmod S7 or both the Cmod S7 and the Arty A7 that is downstream of the JTAG HS3?

Thanks,
JColvin

Hello JColvin,

No, in this case the XC7A35T installed on customer board.

As you can see on the first picture, any device was not recognized.

Hi@Leon.k,

Is Vivado (or more specifically, the Xilinx Hardware Manager) or some other software that works with the JTAG chain/FTDI chips open and running while you are attempting to connect to/detect the two FPGAs?

Also, it looks like the FPGAs are correctly detected in the Windows Device Manager (USB Serial Converter A and B). In the interest of me not presuming the wrong thing, what is the Bus Reported Device Description in the Driver Details for those (in Properties)?

Thanks,
JColvin
