Available GPU frequencies changed after OS re-install

I have re-installed OS via JetPack on my Jetson TX2.
The available GPU frequencies were changed after reinstallation.
For example, previous minimum GPU frequency was 140MHz, now it is 114MHz.

I am guessing the change was made by OS reinstallation.
However, I know that frequencies depend on circuit.
Is it possible to change list of available frequencies?

Hi jongho.kim,

What’s the BSP version you tested? We need to know if can help to find the cause if that’s a regression.

Thanks

Hi kayccc,

I don’t know what is BSP.
How can I check BSP version?

If I type

$ uname -a

on my shell on TX2, it shows:

Linux jongho-tx2 4.9.140-tegra #1 SMP PREEMPT Wed Mar 13 00:30:11 PDT 2019 aarch64 aarch64 aarch64 GNU/Linux

Thanks

Hi jongho.kim,

Not sure what the previsions OS is on you device, you may refer to L4T document to get more understanding of the power and clock management:
