hi,

I am working with the imx6qp sabre ai board. Trying to work on i2c device. on probing I can see no clock on the i2c bus. : Probed on "I2C2-SCL" signal can see no clock ticking can somebody help me?

Note: shorted all the places required for i2c2 bus.

Help me how to make i2c-2 bus to work.

current kernel version: 4.1.15.


Regards,

Lavakumar S
