SDA on bq78PL116 held low by slave always.

Hello,

I'm having an issue with interfacing to a bq78PL116. I have two identical battery packs. One works fine with the GPIO USB adapter from TI and the other not. The second pack use to work....voltage on the SDA and SCL pins have never exceeded 5V.

The SDA line is pulled low by the slave(PL116) all the time! The pack is charged. The SCL line is high.

The GPIO tool has pull up resistors.

Any Ideas?

Thanks ,

Bruce
