Hi,

I am unable to find this info anywhere but what is the value of internal pull-up on the AGX Orin?

Hi al3xh,

Are you using the devkit or custom carrier board for AGX Orin?

Do you mean the resistor of internal pull-up for the pin?

Yes I would like to know the resistor value of internal pull-up for each pin.

I would like to know the internal pull-up resistance value when a pin is configured as PU via the pinmux spreadsheet.

On Jetson AGX Orin, the internal pull-up / pull-down resistors are approximately 50 kΩ.
When you configure a pin as PU in the pinmux spreadsheet, you’re enabling this ~50 kΩ weak pull-up; there isn’t a per-pin resistance table, and for precise biasing you should still use external resistors.
