Hi, all,

I am working on a board based on i.mx283, since don't need to support lithium battery, it have a change in battery relevant circuit, as the attachment show.

 

The problem is, on this board , the VDD4P2 is measured as 1.1V, not supposed 4.2V, and the CPU can't work properly, my question is, is it because that change lead to this wrong voltage of VDD4P2? if it is, why?

 

Any help appreciated, thanks.
