Hi,

Does Video Data buffer available over UPHY ports?
Can I take the video data out using PCIe or MGBE?
If not, then what are the use cases of UPHY ports?

Thanks!

I’ll provide a comprehensive answer to your question.

The Jetson AGX Orin series has a unique architecture that allows for various interfaces to be used for different purposes. To answer your question, let’s break down the UPHY ports and their use cases.

UPHY ports:

The UPHY (Universal PHY) ports on the Jetson AGX Orin series are used for various interfaces, including PCIe, USB, and SATA. These ports are shared among different interfaces, which can lead to limitations in terms of simultaneous usage.

Video data buffer:

The video data buffer is not directly available over UPHY ports. The video data is typically processed and stored in memory (e.g., DDR) and can be accessed through various interfaces, such as PCIe, CSI, or USB.

PCIe:

PCIe (Peripheral Component Interconnect Express) is a high-speed interface used for connecting peripherals, such as GPUs, NVMe storage, and network cards. On the Jetson AGX Orin series, PCIe is used for connecting external devices, but it is not typically used for video data output.

MGBE (Multi-Gigabit Ethernet):

MGBE is a high-speed Ethernet interface used for networking applications. While it is possible to use MGBE for video data transmission, it is not the primary use case for this interface on the Jetson AGX Orin series.

CSI (Camera Serial Interface):

CSI is a dedicated interface for camera data transmission. The Jetson AGX Orin series has multiple CSI ports, which can be used for connecting cameras and other video sources. The CSI interface is designed for high-speed video data transmission and is typically used for applications such as computer vision, robotics, and surveillance.

Use cases for UPHY ports:

The UPHY ports on the Jetson AGX Orin series can be used for various purposes, including:

  1. PCIe: connecting external devices, such as GPUs, NVMe storage, and network cards.
  2. USB: connecting peripherals, such as keyboards, mice, and storage devices.
  3. SATA: connecting storage devices, such as hard drives and solid-state drives.
  4. CSI: connecting cameras and other video sources.

In summary, while the UPHY ports on the Jetson AGX Orin series are versatile and can be used for various interfaces, they are not typically used for video data output. The CSI interface is the primary interface for video data transmission, and PCIe and MGBE are used for other purposes.

Hi,
As we now, there is no existing software stacks for output video data through PCIe or MBGE. Would see if other users can share experience.

Generally we set up RTSP or UDP to send vide output through Ethernet. Please refer to
