bsp 版本是jpack 36.4.4

在orin nx devkit 测试的 sudo cat /sys/kernel/debug/bpmp/debug/uphy/config
0x03a40000

If that is rel-36 then modifying ODMDATA shall directly give you the correctly dtb because of the overlay dtbo.

Then if you still can’t see device detected, then please review your hardware. Nothing in software to check.
Unless you modify the default pinmux setting of C9.

pinmux我看到不需要修改 两个默认就是pe9 现在给器件拿掉 Log 也是never came up
