Hi all,
Just ran into a confusing situation.
On ZCU104's documentation (ug1267), it claims that ZCU104 supports SD1-3.0; but this conflicts with two things.
1. It conflicts with Vivado default setting, Vivado says “MIO45-51" and SD 2.0
2. It conflicts with the shcematic, MIO39-44 are not connected, thus SD 3.0 should not be possible. More over, does SD2.0 also requries level shifter?
Also attached, Vivado SD 3.0 interface selection:
What is going on?
Thanks ahead.

Although, there are a couple of confusion I still have:
1. Why does boot mode 1110 (SD1-LS) still works without the necessary pin connected, and
2. Why does boot mode 0101 (SD1-2.0) does not work, since it uses essentially the same pin as the zcu104 SD pin?
