Tool/software:

Hi

We are testing it by designing it according to the previous guide.
However, other portable devices can charge, but only the Galaxy S24 won't charge. (The S25 is normally charged.)
May I know what the problem is?

Thanks

    Hi David,

    What do you mean by "won't charge"?

    No power draw, no VBUS voltage?

    Does VBUS go to 5-V?

    Can you obtain and share scope captures of VBUS, D+, and D- for working and non-working cases?

    An issue with a single phone indicates a potential issue with the phone. Are you using a type-A to type-C cable? Do you use the same cable between the S24 and S25?

    Thanks and Regards,

    Chris
