Hi Dhanush
for i2cdump usage and expected output one can look at sect.4.20 IIC i.MX6-UltraLite Linux tutorial

Hi igor,
since the wm8960 codec is placed in i2c2 ,so im using the commands.
i2cdump -y 0x1a.
output table is entirely filled only with xx.
im not able to set the values also by using command
i2cset -f -y 1 0x1a 0x11 0xff.
How can i resolve this issue?
Thanks & rgds

Hi igor,
If im not able to get/set the i2c values by using commands, what can be the
reason.
i2cget -f -y 0 0x1a 0x11
i2cset -f -y 0 0x1a 0x11 0xff
