Planning to add an eMMC to Jetson Orin Nano

we are planning to create a custom carrier board with an eMMC on Jetson Orin Nano.

I am looking for a reference schematics for AGX Orin Nano because I read that it has an eMMC and I would like to see how it was implemented on the AGX Orin. I was able to find the schematic for AGX Orin Nano carrier board but not for the module with the eMMC.

Also, I read that Jetson Orin Nano doesn’t support eMMC ? will a better strategy to use a USB to eMMC to be able to interface the Jetson Orin Nano to eMMC?

Based on the provided context, it appears that you are looking for reference schematics for the AGX Orin Nano module with eMMC, but you were unable to find it. Additionally, you are concerned about the compatibility of Jetson Orin Nano with eMMC.

Firstly, it’s essential to clarify that the Jetson Orin Nano module does not have an onboard eMMC. The AGX Orin Nano carrier board, which is a separate entity from the module, might have an eMMC, but the module itself does not.

Regarding the compatibility of Jetson Orin Nano with eMMC, it’s true that the module does not natively support eMMC. However, this does not mean that you cannot use eMMC with the Jetson Orin Nano.

One possible strategy to interface the Jetson Orin Nano with eMMC is to use a USB-to-eMMC adapter or a USB-based eMMC module. This approach would allow you to connect the eMMC storage to the Jetson Orin Nano via USB, effectively bypassing the lack of native eMMC support.

Using a USB-to-eMMC adapter or a USB-based eMMC module has its advantages, such as:

  1. Flexibility: You can use any eMMC storage device with the Jetson Orin Nano, as long as it is compatible with the USB interface.
  2. Ease of implementation: You don’t need to worry about designing a custom eMMC interface on your carrier board, as the USB interface is already available on the Jetson Orin Nano.
  3. Cost-effectiveness: Using a USB-to-eMMC adapter or a USB-based eMMC module might be more cost-effective than designing a custom eMMC interface on your carrier board.

However, it’s essential to consider the following factors when using a USB-to-eMMC adapter or a USB-based eMMC module:

  1. Performance: The USB interface might introduce additional latency and overhead, which could impact the performance of your system.
  2. Power consumption: The USB interface might consume more power than a native eMMC interface, which could affect the overall power consumption of your system.

In summary, while the Jetson Orin Nano module does not natively support eMMC, you can still use eMMC storage with the module by using a USB-to-eMMC adapter or a USB-based eMMC module. This approach offers flexibility, ease of implementation, and cost-effectiveness, but you should consider the potential performance and power consumption implications.

As for the reference schematics, you may want to consider the following options:

  1. Check the NVIDIA website: You can search for the AGX Orin Nano carrier board schematics on the NVIDIA website, which might provide some insights into the eMMC implementation.
  2. Contact NVIDIA support: You can reach out to NVIDIA support and ask for guidance on implementing eMMC on a custom carrier board for the Jetson Orin Nano.
  3. Consult with a third-party design house: If you’re not experienced in designing custom carrier boards, you may want to consider consulting with a third-party design house that has experience with NVIDIA modules and eMMC interfaces.

Remember to carefully evaluate the trade-offs and implications of using a USB-to-eMMC adapter or a USB-based eMMC module, and consider seeking guidance from NVIDIA support or a third-party design house if needed.

It is not possible to work because there is totally no sdmmc/sdio pin that could be used on Orin Nano.
Orin Nano/NX modules don’t have any eMMC signals on the module connector.
