Jetson Agx Orin 32G模组使用Jetpack5.1.5,pcie@14180000 作为PCIE打开(dts status=okey)后,phy初始化失败

报错信息如上,在论坛上看到有相关的帖子解决办法参考Jetson AGX Orin Platform Adaptation and Bring-Up — NVIDIA Jetson Linux Developer Guide

但是在jetpack5.1.5的kernel源码中没有找到tegra234-p3737-0000+p3701-0000.dts,请问下要如何修改

Based on the provided context, it appears that you are looking for information related to the Jetson AGX Orin platform, specifically the image file “990233” with a size of 192 KB.

The context suggests that this image file is related to the Jetson AGX Orin Platform Adaptation and Bring-Up process, which is a part of the NVIDIA Jetson Linux Developer Guide.

Here’s a comprehensive overview of the information that can be gathered from the context:

  1. Jetson AGX Orin Platform: The Jetson AGX Orin is a high-performance AI computing platform designed for edge AI applications. It is part of the NVIDIA Jetson family of products.
  2. Platform Adaptation and Bring-Up: The Platform Adaptation and Bring-Up process is a critical step in setting up the Jetson AGX Orin platform. This process involves configuring the platform’s hardware and software components to work together seamlessly.
  3. Image File: The image file “990233” with a size of 192 KB is likely a firmware or software image file that is used during the Platform Adaptation and Bring-Up process.
  4. Jetpack 5.15: The mention of “jetpack515” suggests that the image file is related to Jetpack 5.15, which is a software development kit (SDK) provided by NVIDIA for the Jetson platform.
  5. Kernel: The mention of “kernel” and “tegra234” suggests that the image file is related to the Linux kernel that runs on the Jetson AGX Orin platform. Tegra234 is likely a reference to the Tegra X1 processor, which is used in the Jetson AGX Orin platform.
  6. Device Tree: The mention of “dts” suggests that the image file is related to the device tree, which is a data structure that describes the hardware components of the platform.

In comparison to other Jetson platforms, the Jetson AGX Orin platform is a more powerful and feature-rich platform, with a focus on edge AI applications. The Platform Adaptation and Bring-Up process for the Jetson AGX Orin platform is likely to be more complex and involved compared to other Jetson platforms.

Overall, the image file “990233” with a size of 192 KB is likely a critical component of the Jetson AGX Orin Platform Adaptation and Bring-Up process, and is used to configure the platform’s hardware and software components for optimal performance.

請你就看一下你flash的log裡面是用哪一個kernel dtb. 然後再去改那個對應的dts檔案就行了
從來就不用去背該改哪一個檔案.

按照文档修改后pcie的打印信息有增加

测量这个PCIE的100M时钟信号,没有测量,现在不确定哪里有问题

請確認pinmux有沒有修改.

imagePINMUX中更改了

線接錯了吧… E14/E15是給PCIe C7用的

有相关配置手册吗?

硬體部分請參考design guide

好的;顺便问一下,在更改完PINMUX和设备树后重新烧录 使用命令sudo ./flash.sh -k A_MB1_BCT jetson-agx-orin-devkit mmcblk0p1是否正确?

請做整機燒機. 不要單燒一個partition.

整机烧录有没有比较快的方法?用命令sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1烧录等待的时间要很久

请问下ORIN 32G的PCIE的CLK和RESET是不是必须按照设计手册上的指定引脚,是否可以更换引脚?现在飞线不太好处理,有没有什么补救办法?

無法更換. 得照上面使用指定的

PCIE设备的PCIE CLK能否使用外部的CLK BUF生成,不使用AGX本身的?

This is not supported.
