After first reboot, led is blinking/staying white

[jaytonic]

Hi,

When I first installed the plugin, everything was working fine, rainbow on idle, solid color on printing and specific color on success or failed print.

I did 4 prints with it during 30h, perfect.

But now I restarted the printer and

1. The leds stays white most of times
2. Sometimes, le led blink to another color(I think the color they are supposed to be).

I've checked the settings, they have still the same value as the other day. I think that the operations that have been ran as root may have not been persisted correctly. Is this possible? How do I check this?
And if it's the case, how do I persist them?

I've a raspberry 4B 8GB,
octoprint 1.4.2 with python 2.7
The plugin is at version 1.7.2

I've used another module in the past, that was not properly working and now I've in my /boot/config
core_freq_min=500
core_freq=250

Maybe something is wrong here?

I tried several other things, removing core_freq_min, only setting core_freq.

But what has solved my issue is to set the core_freq=500. I think this is required to use it with the Rpi 4.
