AGX Xavier NX platform SPI2_MISO multiplexing function is configured as GPIO, and the pin level cannot be pulled down。
I use the Pinmux tool to Set Pin GPIO3_PCC.01
and Set the pin multiplexing function to GPIO output function and drive the pin to low level in the driver Program. After the system is up, the corresponding pin of cat /sys/kernel/debug/gpio is output low, but through the voltmeter Test, the pin level is always high. I would like to ask the current pin (multiplexed with SPI2_MISO). Does this pin have any special output?

hello guwen,

you should access pinmux spreadsheets through download center, please also update the Filled in by Customers columns for pin configuration.
you may also refer to developer guide, please check Pinmux Changes for the instructions.
thanks
