BQ34Z100-G1: BQ34Z100G1 ROM mode isue

Part Number: BQ34Z100-G1

Hello,

on some PCBs I have the problem after flash the golden image and change from I2C to HDQ mode I can not read the registers.

I can see, that the fuelgauge enter to ROM mode, but when i like to disable the ROM mode he go back to I2C mode.

On this kind of PCBs it's not possible for me to enter correct to HDQ mode.

Why dose this problem only happen on few PCBs and how can I solve this?

Best Regards,

Daniel Huhn
