hello TI
We are debugging 983 and 988，but problem，983 Unable to access 988 through I2C pass through.
(1) hardware info：
983（i2c slave: 0xc）988（i2c slave: 0x2c）
(2) The following are the registers we have set up：
set "i2c_addr=0xc"
adb wait-for-device
adb root
adb wait-for-device
adb shell i2cset -y 2 0xc 0x1 0x43 b

timeout 1
adb shell i2cget -y 2 0x2c 0x0
i2cget: i2c_read_byte: No such device or address
(3) 983 register(0x08) value: 0x58, This field is automatically configured by the Bidirectional Control Channel once RX Lock has been detected

之前发过英文论坛，但是都因为NDA问题被删了，发私信也没人回复，也没收到相关邮件，请帮忙代替联系US TI，谢谢！
