How to config SPI7_SCK/SPI7_MISO/SPI7_MOSI/CAN2_DIN four pins as GPIO in Jetson AGX Orin

[allen_tsai]

Hello,
Our HW design use the four pins as GPIO pins.
● SPI7_SCK F37,(FSI_GPIO12)
● SPI7_MISO F36,(FSI_GPIO13)
● SPI7_MOSI E35,(FSI_GPIO14)
● CAN2_DIN G39,(FSI_GPIO08)
I found I can’t use the excel “Orin_Jetson_Series_Pinmux_Config_Template_2.0.xlsm” config them as gpio.
E35 RSVD SNN_GP197_FSI_SPI7_MOSI
F36 RSVD SNN_GP196_FSI_SPI7_MISO
F37 RSVD SNN_GP195_FSI_SPI7_CLK
G39 RSVD SNN_CAN2
Could the four pins be as gpio pin?
If yes,how to config them as gpio pins.

Thank you.

Hi allen_tsai,

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

Do you mean the above pins?
If so, they are un-used by default and can only be used as SPI which you can find them in column E to J.

Hi Kevin,
We bought SOM and customized circuit for our AGX Orin POC project.
I use the devit and my Jetpack version is JetPack_6.2.
We will jump wire to the other GPIO pins and avoid to choice FSI_GPIO pins.
Thank you for your reply.
