你好,我们自己做的一个开发板,C5插上I225,在UEFI shell 下,输入命令pci,可以看到设备,但是开机进入系统后,lspci找不到设备,请问C5还要修改哪里进行适配吗?谢谢!
Moving to Jetson AGX Orin forum
C5 is already enabled by default device tree and actually nothing needs to change in software.
很感谢你的回复,我们没有修改设备树。就是发现UEFI shell下是可以看到pcie设备,开完机之后就找不到设备。这种现象能解释为什么吗?谢谢!
It is common for link failure of a PCIe if your make your own hardware. Mostly hardware or link training problem.
Below debug tips might help.
按照文档修改完毕( Jetson AGX Orin Platform Adaptation and Bring-Up — NVIDIA Jetson Linux Developer Guide),重新烧录系统后,插上pcie设备,UEFI似乎都没有进去,开机debug信息:
pciedebug.txt (41.1 KB)
如果不插上pcie设备,可以正常进入系统,开机debug信息:

I don’t know what thing did you change there … there is nothing in the document that would affect UEFI…
