Tool/software:
I have been working on the BQ24725A for a while but there is a problem.
It works unstable, sometimes it works in some unknown cases, sometimes not.
So I need to check if the software configuration is good and if there is any other requirement for its charging to work.
Could you please check if the following configurations are suitable and inform me if another scenario or something else is needed?
