This is the configuration for the XADC Wizard for the Digilent´s Base system. I have built it without problems with version 2021.1 of Vivado ML

I'm sorry you're having so much trouble with your devices. During this program I have had several moments of frustration like this but I think I have become hooked on the program and the desire to prove to myself that I was capable of continuing has been stronger.

With the current thermal camera project that I am trying I have begun to have problems with Vivado, the project is already very large and there are times that you have to try several times to generate the bitstream despite not making any changes at the end after several attempts it manages to generate. I suspect it must be some job that sometimes gets stuck and is needed for a next step.

I also have had to increase the internal memory to 128K in addition to passing the data to the DDR3 memory from the linker options in Vitis. The thermal sensor and the animation on the VGA screen require a lot of memory.

I haven't tried the XADC yet, but the project that is initially loaded on the Arty includes the configuration of the analog inputs for the Arty S7 50.
