硬件：jeston agx orin 64GB开发套件；自定义载板；
软件：jp6.0
适配过程：
1.更改bootloader相关，

3.添加phy驱动
目前的问题：eth0能连接，能设置ip，不能更改mtu，ping时有arp，但ping不通

Hi,

If you are designing a custom base board, then it means some adaptation configurations are needed.
Otherwise, your board may not work fine.

For Orin AGX series, you could refer to below document
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxOrinSeries.html?highlight=universal%20serial%20bus#jetson-agx-orin-platform-adaptation-and-bring-up
(please be aware that above link is for rel-36.3/jetpack6.0)

This document includes below configuration

  1. pinmux change & GPIO configuration
  2. EEPROM change as most custom boards do not have an EEPROM on it.
  3. Kernel porting
  4. PCIe configuration
  5. USB configuration
  6. MGBE configuration
  7. RGMII configuration

Thanks!

已经做了，现在的问题，不知道咋解决，没有排查方向了

Rx部分的pinmux全部沒有設對

是这部分吗nvidia,pull = <TEGRA_PIN_PULL_NONE>;全部改成TEGRA_PIN_PULL_UP？
