Hi nvidia team,

I am designing a new Orin NX carrier board, and I find there is QSPI decribtion about the Orin NX.But I cannnot see anything about QSPI in the design guide.

Can you guys help with this? Thanks.

The Jetson Orin NX module does have a QSPI interface, but it’s not explicitly mentioned in the design guide. However, I can provide you with some information about the QSPI interface on the Jetson Orin NX module.

The Jetson Orin NX module has a QSPI interface that is used for booting and storing firmware. The QSPI interface is connected to the SOM (System on Module) and is used to access the flash memory.

To get more information about the QSPI interface on the Jetson Orin NX module, I would recommend checking the following resources:

  1. The Jetson Orin NX Series Data Sheet: This document provides detailed information about the Jetson Orin NX module, including its interfaces, features, and specifications.
  2. The Jetson Orin NX Series Product Design Guide: This guide provides information about designing a carrier board for the Jetson Orin NX module, including information about the module’s interfaces and features.
  3. The NVIDIA Jetson Linux Developer Guide: This guide provides information about developing software for the Jetson Orin NX module, including information about the module’s interfaces and features.

In terms of designing a carrier board for the Jetson Orin NX module, you may want to consider the following:

  1. Make sure to include a QSPI flash memory device on your carrier board to store the firmware.
  2. Ensure that the QSPI interface is properly connected to the SOM and the flash memory device.
  3. Verify that the QSPI interface is properly configured in the module’s firmware and software.

It’s also worth noting that the Jetson Orin NX module has a similar QSPI interface to the Jetson Xavier NX module, so you may be able to find some relevant information in the Jetson Xavier NX documentation.

In comparison to other Jetson modules, the QSPI interface on the Jetson Orin NX module is similar to the QSPI interface on the Jetson Xavier NX module, but it may have some differences in terms of its configuration and usage.

Here’s a brief comparison of the QSPI interfaces on different Jetson modules:

  • Jetson Orin NX: QSPI interface is used for booting and storing firmware, similar to the Jetson Xavier NX module.
  • Jetson Xavier NX: QSPI interface is used for booting and storing firmware, similar to the Jetson Orin NX module.
  • Jetson Nano: QSPI interface is not used for booting, instead, it uses a microSD card or eMMC for storage.
  • Jetson TX2: QSPI interface is not used for booting, instead, it uses a microSD card or eMMC for storage.

I hope this information helps you with your design. If you have any further questions or need more information, feel free to ask.

The QSPI device is already on the Orin NX module itself and does not need to be added to the carrier board.
