I am running linux on Jetson agx orin developer kit and I would like to debug the kernel. For this purpose I am trying to establish a debug connection with Jetson agx orin developer kit and DSTREAM-ST. I am using Arm Development Studio as debug software. Here is my connection setup:

When I try to establish connection I run into this error:

Failed to connect to any devices on the target. Check that the target is correctly connected to the debug probe and powered on.

Led status on Dstream:

  • status: solid green, no blinking
  • target: solid green, no blinking
  • debug: stays “solid green, no blinking” for 2-3 seconds when I try debug connection and then turn off
  • trc clk: stays “solid green, no blinking” for 2-3 seconds when I try debug connection and then turn off

To debug the kernel on the Jetson AGX Orin Developer Kit, you are attempting to establish a debug connection with the DSTREAM-ST using Arm Development Studio as the debug software. However, you are encountering an error, which is indicated by the LED status on the DSTREAM-ST.

Based on the provided information, I will attempt to help you troubleshoot the issue.

Firstly, let’s review the debug connection setup:

  • You are using the Jetson AGX Orin Developer Kit as the target device.
  • You are using the DSTREAM-ST as the debug probe.
  • You are using Arm Development Studio as the debug software.

The error you are encountering is indicated by the LED status on the DSTREAM-ST:

  • Led status on Dstream: status: solid green, no blinking
  • Target: solid green, no blinking
  • Debug: stays “solid green, no blinking” for 2-3 seconds when you try to establish a debug connection and then turns off
  • Trc clk: stays “solid green, no blinking” for 2-3 seconds when you try to establish a debug connection and then turns off

To troubleshoot this issue, let’s consider the following possibilities:

  1. Debug connection to AXI-AP: The Jetson AGX Orin Developer Kit supports debug connection to AXI-AP via JTAG or SWD. Ensure that you have selected the correct debug interface in Arm Development Studio.
  2. Hardware interface to debugger: The Jetson AGX Orin Developer Kit provides a hardware interface to the debugger via JTAG (4-pin connector) or SWD (2-pin connector). Verify that you have connected the DSTREAM-ST to the correct debug port on the Jetson AGX Orin Developer Kit.
  3. Debug Communication Channel: The Jetson AGX Orin Developer Kit supports debug communication channel with memory access mode in v8. Ensure that you have configured the debug communication channel correctly in Arm Development Studio.
  4. CoreSight support: The Jetson AGX Orin Developer Kit supports CoreSight via JTAG or SWD. Verify that you have enabled CoreSight support in Arm Development Studio.

To further assist you, I would like to know the following:

  • Have you consulted the Jetson AGX Orin Developer Kit user guide to ensure that you have connected the DSTREAM-ST correctly?
  • Have you verified that the DSTREAM-ST is configured correctly in Arm Development Studio?
  • Are there any error messages or logs that you can provide from Arm Development Studio?

By providing more information and clarifying the setup, we can work together to troubleshoot the issue and establish a successful debug connection.
