UNUSED pin DT file setting

[netkerl]

In the DT file, the pin-map is defined in the existing DT file for the UNUSED pin (ex: L19pin: PEX_C6_CLKREQ_N: GPIO3_PAF.02 Input No Enable Disable
) Should I select “unused PEX_L6_CLKREQ_N” for this?

Hi netkerl,

Are you using the devkit or custom board?
What’s your Jetpack version in use?

I’m not clear about what do you mean about “unused”.
Could you help to provide the DT file you are modifying?

I’m using the custom board (my own H/W design board using NVIDIA-provided schematic)
Linux is not ported yet, and I’m preparing Linux porting.

I changed to unused xxx for not using CVM connector pin as following

		AO_HV (3.3V Capable)	VDDIO_C
D59	CAN0_DOUT	CAN0_DOUT	GP17_CAN0_DOUT	19.5K +/- 35%	z	unused_CAN0_DOUT	Not Assigned	Int PU
F58	CAN0_DIN	CAN0_DIN	GP18_CAN0_DIN	19.5K +/- 35%	z	unused_CAN0_DIN	Not Assigned	Int PD	No
H61	CAN1_DOUT	CAN1_DOUT	GP19_CAN1_DOUT	19.5K +/- 35%	z	unused_CAN1_DOUT	Not Assigned	Int PU
B61	CAN1_DIN	CAN1_DIN	GP20_CAN1_DIN	19.5K +/- 35%	z	unused_CAN1_DIN	Not Assigned	Int PD	No
E59	GPIO06	CAN0_STB	GP21	19.5K +/- 35%	pd	unused_CAN0_STB	Not Assigned	Int PD	No

If you are developing a custom carrier board for AGX Orin, please just using pinmux spreasheet to configure them or just configure them as GPIO instead of CAN usage (in your case).
