Based on the provided context, it appears that you are asking about the Jetson AGX Orin and its compatibility with different headers and power modes.

The Jetson AGX Orin is a high-performance module that supports various power modes, which can be configured using the nvpmodel command. The power modes determine which CPU cores are used and the maximum frequency of the CPU and GPU.

Regarding the compatibility of the Jetson AGX Orin with different headers, the device tree overlay for a hardware module must define the overlay-name property, the jetson-header-name property, and the compatible property.

The jetson-header-name property specifies the expansion header with which the hardware module is associated. For the Jetson AGX Orin, the supported headers are:

  • 40-pin expansion header (Jetson 40pin Header)
  • M.2 Key E slot (Jetson M.2 Key E Slot)
  • CSI connector (Jetson AGX CSI Connector)

The compatible property indicates which combination of Jetson module and carrier board the overlay supports. For the Jetson AGX Orin, the compatible property values are:

  • nvidia,p3737-0000+p3701-0000
  • nvidia,p3737-0000+p3701-0004
  • nvidia,p3737-0000+p3701-0005

In comparison to the Jetson Orin NX and Nano series, the Jetson AGX Orin has different compatible property values and supported headers.

Regarding the power modes, the Jetson AGX Orin supports various power modes, which can be configured using the nvpmodel command. The power modes determine which CPU cores are used and the maximum frequency of the CPU and GPU.

In summary, the Jetson AGX Orin is a high-performance module that supports various power modes and is compatible with different headers, including the 40-pin expansion header, M.2 Key E slot, and CSI connector. The device tree overlay for a hardware module must define the overlay-name property, the jetson-header-name property, and the compatible property to ensure compatibility with the Jetson AGX Orin.

However, the provided context does not mention anything about the “Jeston AGX Orin40pinuartauarta” specifically. It seems like there might be some typo or missing information. If you could provide more context or clarify what you mean by “Jeston AGX Orin40pinuartauarta”, I would be happy to try and assist you further.

Hi 2595898530,

You can refer to https://elinux.org/Jetson/L4T/peripheral/#Mapping_3 for UART mapping on Jetson device.

The address for UART-A should be 3100000.serial, please check if it is enabled in device tree and listed in dmesg.
