Hi Katlynne,

I'm not getting any errors when I run the GUI. The DAC is not getting detected after loading the DXP DAC Exerciser Programmer.

Thanking you

Hi Vivek,

Do you have admin rights on the computer. When you ran the installer did you run as administrator? That might help ensure no files are missed in the install.

During the install, did the WinUSB drivers install on your computer. Make sure the EVM is not connected during any step of the installation.

Do you have the EVM configured per steps 1 & 2:

Hi Katlynne,

I had run the installer as Administrator. The EVM was also not connected. I'm attaching few screenshots of the driver being listed

after loading the DAC Exerciser Programmer.

Best,

Hi Vivek,

I think we have seen this issue before on windows 10. Basically, Windows 10 requires drivers to be "digitally signed". It can be disabled, but there are a number of steps to accomplish that.

Can you try this? It is a bit of a pain, but it is the only workaround we have for the new driver requirements.

We are working on replacing many of the EVM tools and the DXP software. We currently have the DAC8811 EVM being refreshed and we can sample that to you if you like. It is the single channel version of the DAC8814.
