We are working on Serializer( DS90UB925Q) and Deserializer custom board. The operating system is Linux. We now have problems on I2C pass through to multiple remote i2c devices. There are four remote slaves on the 926 side and would like to talk to it using a master on the 925 side. We can access the 925 registers to enable the i2c pass through. It seems that there is only one register [reg7] that can be programmed. If we write the specific remote i2c slave address into reg[7] and reg[8], that specific remote i2c slave can work well. However, we have four remote i2c slaves.
My question is : Could the 925 i2c work as i2c multiplexer to connect more i2c slaves on 926 side simultaneously?
