USB-C ammeter takes 5V
PPBUS is 12.3V
3V8_AON is present
1V8_AON is present
PP3V3_S2 was not present but I found UC710 corroded so I replaced it and now I got 3V there but no 3.3V.. enable P3V3S2_EN is not present.. generated by U8100, master PMU.
I swapped the master PMU and slave PMU from a known-good donor board and my bad board still takes 5V..
I put the master and slave that I have removed from by bad board to the donor.. and it takes 20V. Meaning the chips are probably OK.
PP3V3_S2_UPC missing..
PP1V8 S2 missing
PP1V25_S2 missing
I don't know where else to look at..
I currently have U8100 removed to have some diode mode measurements to try and help me..
Please give me a lead or a hint on where to look next
