Hi Modalai,

For the new sdk 1.1.1 if we want to set the voxl2 to performance mode do we follow the same instruction here 

https://docs.modalai.com/thermal-and-performance/

It seems that when we cat we have a diffferent string and trying to use the command to pipe the string performance does nothing 

Thanks

Adding more information (I work with Jeffrey), we get an error
```
[ Error writing lock file /sys/devices/system/cpu/cpu0/cpufreq/.scaling_governor.swp: Permission denied ]
``` 
I can't seem to delete the .swp file either. 

Thanks!

@mrunaljsarvaiya are you using VOXL 1 or VOXL 2? You're pointing to the VOXL 1 user guide. 

It may not be well documented, but voxl-cpu-monitor can set the scaling mode in its config file

@Moderator Hi We are using Voxl2.

Do you have any documentation for voxl-cpu-monitor or where it is for Voxl2 any starting point would be helpful

@Jeffrey-Mao I would first run `voxl-configure-cpu-monitor factory_enable` to enable the service with default settings.

Then, you can modify the config file at `/etc/modalai/voxl-cpu-monitor.conf` and change `normal_cpu_mode` to `performance`

@tom The conf file also has some comments that describe other possible config options
