Hi @fernando79513, I appreciate your efforts. But here are some thing that you have to understand.

1. The cpu_idle.py in contrib area is a bit out of date since we added additional SoC, mt8370, recently.

• You can reference the latest script here: https://git.launchpad.net/~baoshan-team/baoshan/+git/checkbox-provider-baoshan/tree/bin/cpu_idle.py

2. f-string is supported from python 3.6 , therefore, all the f-string snippet have to be modified, otherwise, Checkbox's CI will break on python 3.5 checking.
