Hello,
I recently bought bq34z100evm and ev2400 to measure battery capacity. I connected to my PC and instal bq Gas Gauge Evaluation Software 0.9.90. When I tried to write data to data flash connection between PC and EV2400 got lost and bq34z100 on bq34z100 stopped working ( REG25 and VSS got connected). I replaced bq34z100 to a new one and tried to connected it but the software does not recognize the bq34z100evm any more. Every voltage point on bq34z100evm looks ok. Can you help me to determine were is the problem?
