Hi,Everyone

I have a question.We use AM335x.

GPIOs of AM335x are Hi-Z when GPIO is input ?
I wanna make sure AM335x can be set Hi-Z on GPIO pin

Hi,

You can find parameters in section 5.7 of the AM335X Datasheet Rev. I. Look for data for "All other LVCMOS pins"

Hiroyasu,
Biser gave you the electrical characteristics of Hi-Z inputs: he refers to the am335x datasheets as the characteristics depends on VDDSHVx.
For pin mux configuration, refer to the latest version of the Technical Reference Manual (TRM) in "Control Module" / "Pad Control Registers" chapter.

Regards.
