Part Number: DS90UB953A-Q1

Tool/software: Linux

now i can config 953 from 954 at remote side fellow that:

config 0x58 0X5b 0x5c to register an alias ID ,make it mapping to 0x30(my 953's slave id)

Hello MSC4456,

Make sure you have the correct DES_ID in reg 0x37.
Enable I2C Pass through in reg 0x32.

Thanks !!!

the data read from 0x37 is 0x60(my ds90ub954 slave device ID)

then i try to do like you say,

0x30 0x32 0x59

and now i can config 954 from the remote side.

R 0x60 0x00 ->0x60

other question:

if i want to config the slave device which connected on 954 i2c pins, what need i do?

i try to config 0x30 0x39 0x76(slave id)

0x30 0x41 0x76(slave id)

and then config 0x76, reg, data but it seems not working

Your settings are correct.

Do not forget to enable I2C Pass-Throu in the SER (reg 0x32), and diable Pass-Throu in the DES (reg 0x58)
