BQ25638EVM: Not charging to VREG

Part Number: BQ25638EVM

I'm probably missing something super obvious. I'm bringing up my EVM and trying to charge some batteries

I set VREG to 4.35V, but I'm sitting at 4.12V on VSYS/VBAT in CV mode

5.0V, 2A in on VIN (benchtop supply) . No load on Vsys or Vbatt

I'm in CHG_STAT = Taper Charge (CV) ... so I'd expect Vbatt to be my VREG I believe?

Here's my registers. Sorry in advance if it's a simple thing I missed in datasheet or evm user guide Slight smile
