BQ27532: I2C communication problem with bq24250

Other Parts Discussed in Thread: BQ24250

Good day.

I use an evaluation board BQ27532 with BQ24250.

I do succeed to communicate with BQ27532 via I2C. Partially, I can read from and write to all gauge registers.

As far as I understand, communication with BQ24250 is performed via BQ27532. I mean slave address is the same as BQ27532.

But reading from CHARGER STATUS register (0x32) returns me value 0x40 (i.e. I2C communication error between gauge and charger).

What may be wrong?

Thank you in advance.
