Hi,

We try to boot Orin AGX on our custom platform that was design for Xavier before.
As POC I try to boot Orin AGX on Xavier AGX NVidia carier(p2972) and stack with issue that interface in “up” state but don’t “see” link
Used:

1. L4T 35.4.1 (JP 5.1.2)
2. Device tree modifications according to Adaptation Guide
3. Applied patch from this topic
4. Modified kernel sources according to this topic
5. Disable EEPROM(not in use in final design)
6. Disable GBE in ODM data (p3701.conf)

If you can help with this issue it will be great.

Fixed. Please close this case. Issue was in missing definition in gpio pinmux file.
Pin Series file didn’t generate entry for GPIO G5. Maybe is issue with my Office installation or macros are not compatible with Excel 2016.

If some one need work solution of pinmux and gpio for Orin AGX on NVidia Xavier AGX carrier based board see bellow

1. gpio configuration: tegra234-mb1-bct-gpio-p3701-0000-a04.dtsi (4.8 KB)
2. Pinmux configuration: tegra234-mb1-bct-pinmux-p3701-0000-a04.dtsi (65.7 KB)
