In our new board we faced an issue with Si5332. It is main clock generator in our system and we planed to configure it via I2C interface by MC, but we can't do anything. Every time we transfer generator from READY to ACTIVE mode - all setting are dropped to their default values.
It looks like part had been already preconfigured with something, we can read back DESIGN_ID value "IX_BL".
Maybe someone faced similar problems and can push us in right direction? Or we are stuck with unusable board?
