Thank you so much for JColvin's detailed explanation. That is the problem, and after I changed A0 and A1 to Aux4 and Aux5, the problem is solved.

Someone can help on this question? Thanks so much.

I have an Arty A7-100T. My project is to read the A0 to A5 analog inputs into the MicroBlaze microprocessor and send it out via UART. I was firstly trying to use XADC IP to convert the Analog to Digital without the MicroBlaze yet. However, I can never read the correct data from A0 to A5. Please see the following screenshots as the configuration (currently configured as A0 and A1 channels only). Tried many different combinations without any correct results. So have to ask someone here to help. From the warning message in the implementation, looks like it is because the VP/VN Pins are not assigned properly. Can someone give me some hints or experiences on how should I assign these pins to make it work, that is, the A0 to A5 channels connected to the real ADC inside the FPGA? Thanks so much.
