错误日志 RxErr 表示接受数据时出错。

Jetson Orin NX和Jetson Orin Nano虽然接口类似，但PCIe支持的速率和通道配置可能不同。 Orin NX支持PCIe Gen4，而Orin Nano仅支持PCIe Gen3。

参考设计指南 https://developer.download.nvidia.cn/assets/embedded/secure/jetson/orin_nx/docs/Jetson-Orin-NX-Nano-Design-Guide_DG-10931-001_v1.4.pdf?__token__=exp=1743566016~hmac=0654382574d44a358cd67045c7cbf52250773e3b37d42ee5bea375ac8668af12&t=eyJscyI6ImdzZW8iLCJsc2QiOiJodHRwczovL3d3dy5nb29nbGUuY29tLmhrLyJ9

您好，您给出的链接中我没有看到相关内容，能不能直接告诉我我应该怎么修正这个错误呢？

可以先排除是否为硬件的问题，再查看软件驱动

  • 检查PCIe信号完整性：

    • 使用示波器或信号分析仪检查PCIe信号质量。
    • 确保载板上的走线长度、阻抗匹配符合PCIe规范。
    • 如果使用M.2接口，确保插槽支持所需的通道数（x1、x2或x4）。

  • 电源稳定性：

    • 确保供电稳定，特别是给PCIe设备供电的电源轨。
    • 检查载板是否正确连接了必要的电源引脚（如3.3V、12V）。

  • 参考官方设计指南：

    • 对比您的载板设计与NVIDIA提供的Jetson Orin NX开发套件设计指南，特别是关于PCIe部分的设计。
