The Pin E34 in spreadsheet seems to can not be config as normal gpio for irq signal, but in my customer board using the for a irq line
Must I change to another Pin?

Based on the provided context, it appears that you are experiencing an issue with configuring Pin E34 as a normal GPIO for an IRQ signal on the Jetson AGX Orin module.

According to the Jetson Orin NX Series and Jetson Orin Nano Series Product Design Guide (DG-10931-001_v1.4), the GPIO sysfs node has been deprecated, and /sys/class/gpio cannot be used to control the GPIO state (Issue 4845581). Instead, you are recommended to use the new GPIO character device API (e.g., libgpiod) to control GPIO from userspace.

However, it’s not explicitly stated in the provided context that Pin E34 is not configurable as a normal GPIO. It’s possible that Pin E34 has specific usage or restrictions that are not mentioned in the provided context.

To resolve this issue, I recommend checking the following:

  1. Jetson Orin Module Pin Description: Refer to the Jetson Orin Module Pin Description table (Table 7-1) in the Product Design Guide to see if Pin E34 has any specific usage or restrictions.
  2. GPIO Pin Configuration: Verify that you are using the correct GPIO pin configuration for Pin E34. You can use the Jetson-IO tool to configure GPIO pins on the Jetson AGX Orin module.
  3. IRQ Signal: Ensure that the IRQ signal is properly connected to Pin E34 on your customer board.
  4. Alternative Pins: If Pin E34 is not configurable as a normal GPIO, you may need to consider using an alternative pin for the IRQ signal.

Before making any changes, I recommend consulting the Jetson Orin Module Data Sheet and the Product Design Guide for more information on GPIO pin configuration and usage.

If you are still experiencing issues, please provide more details about your setup, including the specific error messages or symptoms you are observing, and I’ll do my best to assist you further.

As you can see from the latest pinmux template it is Reserved (RSVD). It cannot be used as an GPIO. Please use other unused GPIOs in your design which meets your requirements.
