PCIE_CTRL0_PERST_B pin configuration (imx8dx)

[johny_kim]

If specific pin(PCIE_CTRL0_PERST_B) supports both 1.8V and 3.3V, How can I control this voltage level in IMX8DX?

What register supports this voltage level control?

Hello Hyun Kim,

Unfortunately the i.MX8DX, has not been release, so we are not able to share any information since it is subject to change.

My advise it is that you need to check in the PCIE pads, there is going to be a register that can select the power rail
