I build up a single cell product with BQ28550 recently. However, the smbus communication doesn't work with EV2300 between PC and the product. I was told the pin12 needs to be connected to Vreg (pin5) to enable the smbus communication. But I checked datasheet, it says that is the DQ port, so I leave it floating. This is the new stuff, please help me to fix it. Thanks in advance.
