Jetpack6.2 设备树修改后为何不生效？

[dcb0223]

我想在设备树中关闭 ethernet@6800000节点，为何不能生效？

我可以确认，我修改的地方是对的，并且替换设备树也是正确的，因为我看到了增加的其他节点，但是始终无法关闭这个节点，比如我增加了test节点，都可以看到我设定的值为aaa，即便如此，status依然是okay，无法关闭掉

What is the device tree content when you convert your final dtb back to dts byusing dtc tool?

[dcb0223]

sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

I tried using the above command, and found that the decompiled dts was in the same situation.

I want to disable this node, but the only way to do it is by closing this file. However, this seems illogical.

Hi,

please check dtc tool result on your host PC right after you compile out a new dtb instead of reading runtime device tree from /proc/device-tree.
