问题描述:
1、ORIN在没有上下行网络负载情况下,通过iperf3测试网络的上行与下行均没有明显异常
2、ORIN在有较大下行网络负载情况下,通过iperf3测试网络上行,上网络网速明显下降。
没有下行网络负载前,上行网络正常;高下行负载上,上行网络被影响
3、确认是否自研底板导致ORIN网络异常:
3.1:高负载网络上下行工作正常的ORIN在几块自研底板上测速均正常
3.2:网络上行会被网络下行影响的ORIN在相同的几块自研底板上测速也均不正常
此外已确认AGX orin到网络芯片的硬件连线距离是在ORIN芯片规范范围内。
此问题是否可以通过配置提高IO引脚的驱动电流解决及如何操作; 或其它什么方向进行优化,麻烦提供一些解决思路。
谢谢!

Hi,
For information, do you use Jetpack 6.2.1 r36.4.4?

Hi,
On the custom board, do you connect the PHY through MGBE MDIO? Or which interface?
你好,
是的,基于rgmii与网络芯片连接,该网络设备树配置如下
/* EQOS */
eth0: ethernet@2310000 {
status = “okay”;
nvidia,mac-addr-idx = <0>;
nvidia,phy-reset-gpio = <&tegra_main_gpio TEGRA234_MAIN_GPIO(G, 5) 0>;
phy-mode = “rgmii-txid”;
nvidia,max-platform-mtu = <16383>;
// nvidia,pause_frames = <0>;
fixed-link {
speed = <1000>;
full-duplex;
pause;
};
};

Hi,
Please use the headless rootfs and check if the issue is present:
Root File System — NVIDIA Jetson Linux Developer Guide 1 documentation
Have to use headless rootfs to avoid hitting the known issue:
GUI HDMI setting affect XFI performance
Please give it a try.
hi, DaneLLL:
我按您说的,重刷了minimal的文件系统后,因系统网络无法起来所以放弃了。
网络通讯发送和接收的gpio口是否有驱动电流概念?
谢谢

Hi,
We would suggest try Jetpack 5.1.5 r35.6.2. The known issue is fixed in the version.
On r35.5.0, the minimal rootfs is supposed to work. Somehow you experience the issue. Or you may try basic rootfs:
