I am designing customized carrier board for NVIDIA Jetson AGX Orin AGX 64GB. I am referring document “Jetson AGX Orin Series Modules
Design Guide” but in this document, it is mentioned that we cannot use the same Debug MCU circuit. I am only willing to have UART and JTAG debug can I use the Orin Module JTAG Pins and UART Pins Directly for debugging purpose?

Thanks,

Based on the provided context, I’ll address your question regarding designing a customized carrier board for the NVIDIA Jetson AGX Orin 64GB module.

The Jetson AGX Orin Series Modules Design Guide indeed mentions that the same Debug MCU circuit cannot be used. However, it does not explicitly prohibit the use of the Orin Module JTAG Pins and UART Pins directly for debugging purposes.

In fact, the guide suggests that the JTAG and UART interfaces can be used for debugging, but it recommends using the Debug MCU circuit for more comprehensive debugging capabilities.

Since you are only interested in using UART and JTAG for debugging, you can use the Orin Module JTAG Pins and UART Pins directly. However, please note the following:

  1. JTAG Pins: The Orin Module JTAG Pins can be used for debugging, but you need to ensure that the JTAG signals are properly routed and terminated on your custom carrier board.
  2. UART Pins: The Orin Module UART Pins can be used for debugging, but you need to ensure that the UART signals are properly routed and terminated on your custom carrier board.

To confirm, you can refer to the Jetson AGX Orin Series Modules Design Guide, specifically the sections on JTAG and UART interfaces. Additionally, you can consult the Jetson AGX Orin module datasheet and the NVIDIA Jetson Linux Developer Guide for more information on debugging and using the JTAG and UART interfaces.

In comparison to the Jetson Orin NX module, the Jetson AGX Orin 64GB module has similar debugging capabilities, including JTAG and UART interfaces. However, the specific implementation and routing of these interfaces may differ between the two modules.

In summary, you can use the Orin Module JTAG Pins and UART Pins directly for debugging purposes on your custom carrier board, but ensure proper routing and termination of these signals. Consult the relevant documentation and guides for more information on debugging and using these interfaces.

Hi,
You may refer to design of Orin Nano carrier board, so that you can get uart log by connecting to host PC through USB to TTL cable.

May refer to the pages:
Jetson/General debug - eLinux.org

Hi,

Is there any validated JTAG Debugger there for Jetson Orin AGX 64GB? Could you please suggest some suitable Debuggers?

Thanks,
