You may try this.

Thanks your link，It can work well in AGX platform,but it can’t work in NX platform。

What’s the error message? There’s no problem on my Xavier NX.

[Honey_Patouceul]

What is the filesystem type of your rootfs on NX ?

df -H -T

[blstcvLiu]

I used jetpack 4.4.1.

[Honey_Patouceul]

Ok no fs type problem.

Further looking at your first post, it seems the error is that you were trying to write into max_rate node, that is read-only.
You would set clock rate writing to rate node instead.

cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate |tee /sys/kernel/debug/bpmp/debug/clk/vi/rate

[blstcvLiu]

The max-rate is too low. I want it to be bigger

[ShaneCCC]

You cann’t change the max-rate

OK, thank you for your answer.
