BQ25898CEVM-730: BQ25898CEVM-730 with EV2300 : "Device ACK Error"

Part Number: BQ25898CEVM-730
Other Parts Discussed in Thread: BQ25898

Hi,

I am trying to evaluate BQ25898 IC using EVM and EV2300. I connected both EV2300 and BQ25898EVM as directed in BQ25898EVM user's guide but on battery management studio (tool) i see "Device ACK Error" and I nothing works (can't read registers and no changes in voltage/current values).

I have powered the EVM using a 5V, 2A wall adapter and connected this to J1 (VBUS and GND). I am using a 3050mAh battery, battery voltage is 3.9V, connected battery to J4 (BAT and GND). Jumper positions are as suggested in EVM user's guide and I am using Battery Management Studio v1.3.54.1.

Please suggest if I am doing something wrong or missed something.
