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 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
