Pin connection differences between P3701-0000 and P3701-0005?

Hello,

I would like to ask whether there are any differences in pin connections between P3701-0000 and P3701-0005.

We have successfully set up and verified a sensor on the Jetson AGX Orin 64GB (P3701-0005). However, the same sensor does not operate on the Jetson AGX Orin Developer Kit (P3701-0000).

We applied the exact same DT overlay (DTSO) configuration on both platforms.

We suspect that the SPI communication is not working properly.
Are there any physical pin connection differences between these two modules that could affect SPI?

Thank you in advance for your support.

Based on the provided context, I couldn’t find any specific information about the pin connections between Jetson AGX Orin and Jetson Xavier NX series. However, I can provide some general information about the differences between these two modules.

The Jetson AGX Orin and Jetson Xavier NX series are both part of the NVIDIA Jetson family, but they have different hardware configurations and features. The Jetson AGX Orin is a more recent and powerful module, while the Jetson Xavier NX series is an older generation.

In terms of SPI communication, it’s possible that there are differences in the pin connections or configuration between the two modules. However, without specific information about the pin connections, it’s difficult to say for certain.

That being said, here are some potential differences to consider:

  1. SPI pinouts: The SPI pinouts may be different between the two modules. You can check the datasheets or documentation for each module to confirm the SPI pinouts.
  2. SPI configuration: The SPI configuration may also be different between the two modules. You can check the device tree overlays (DTSO) and configuration files to see if there are any differences in the SPI configuration.
  3. Hardware differences: There may be hardware differences between the two modules that affect SPI communication. For example, the Jetson AGX Orin may have a different SPI controller or clocking scheme than the Jetson Xavier NX series.

To troubleshoot the issue, you can try the following:

  1. Check the datasheets: Check the datasheets for each module to confirm the SPI pinouts and configuration.
  2. Compare device tree overlays: Compare the device tree overlays (DTSO) and configuration files for each module to see if there are any differences in the SPI configuration.
  3. Use a logic analyzer: Use a logic analyzer to capture the SPI signals and compare them between the two modules.
  4. Contact NVIDIA support: If you’re still having trouble, you can contact NVIDIA support for further assistance.

In summary, while I couldn’t find specific information about the pin connections between Jetson AGX Orin and Jetson Xavier NX series, there may be differences in the SPI pinouts, configuration, or hardware that affect SPI communication. By checking the datasheets, comparing device tree overlays, and using a logic analyzer, you may be able to identify the issue and resolve it.

There are no different.
