I2C controller getting timed out

[deepak srinivasan]

Hi all

I am trying to learn device drivers following tutorials from free-electrons on BBB rev 4C

I followed their tutorial trying to enable i2c1 and connecting it to a Nintendo Nunchuk,

My pinmux configuration

        i2c1_pins: pinmux_i2c1_pins {

                pinctrl-single,pins = <

                        0x158 0x32      /* SPI0_D1 */

                        0x15C 0x32       /*  SPI0_CS0 */

                >;

        };

I also enabled I2C-1 by

&i2c1 {

        pinctrl-names = "default";

        pinctrl-0 = <&i2c1_pins>;

        status = "okay";

        clock-frequency = <100000>;

        nunchuk: nunchuk@52 {

                compatible = "nintendo, nunchuk";

                reg = <0x52>;

        };

};

While running $i2detect -r 1, I get connection timed out error on the expected address (0x52)

I was using the Nunchuk before, so I believe there is no problem with slave device

Can someone help by pointing out what error I am doing

regards
