Where is FSI_PADCTL_A2 register?

I am following Here to change the pinmux.
My goal is to control G11 PAD Control Registers.
In AGX Orin TRM v1.0p page 5345, the description said:

The G11 PAD Control Registers are collectively called FSI_PADCTL_A2 in the System Address Map.

But in System Address Map (TRM Page 28 ~ Page 62), I am not able to find “FSI_PADCTL_A2” register.
Not only FSI_PADCTL_A2, nor FSI_PADCTL_A0 & A1 can not be found.

AGX Orin Dev. Kit, JetPack 5.0.2

Please help.
Thank you very much.

Please directly change the pinmux by using the pinmux spread sheet.

Not everything listed on TRM would be working on jetson as TRM only indicates hardware capability.

Hi WayneWWW
Thank you for your reply.
Can you please provide the tutorial of pinmux spread sheet?
I can now generate device tree from it, but I am not able to find a tutorial about using it.
Thank you very much.


Please go to your Linux_for_Tegra BSP folder.

Check bootloader/t186ref/BCT.

There would be tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi and tegra234-mb1-bct-pinmux-p3701-0000.dtsi.

One of them is the pinmux for your board.



One of them would be the file for GPIO configuration.
