Setup:
Vivado 2017.1
Zynq 7Z045FFG676
Zynq reports pin conflict when SD0 card detect is mapped to MIO46 even when no peripheral is using MIO46.
Pls refer to screen cap below. It shows Card detect at MIO46 having red color. I have narrowed down the problem to I2C peripheral. Once I disable I2C pheripheral, MIO46 turns green. I2C is not using MIO46.
Pls ignore "Background task is running..." message as I have started recompile when I did the screen cap.
