Hi

 

In our custom board we are using 3.14.28 kernel.

 

I am not able to get SPI SCLK.

Please check attached ECSPI register detail.

 

dts file modification for ecspi3 is as follows.

 

&ecspi3 {

  fsl,spi-num-chipselects = <1>;

  pinctrl-names = "default";

  pinctrl-0 = <&pinctrl_ecspi3>;

  status = "okay";

 

 

  codec_tas: tas@0 {

  compatible = "tas";

  spi-max-frequency = <20000000>;

  reg = <0>;

  };

};

 

 

pinctrl_ecspi3: ecspi5grp {

  fsl,pins = <

  MX6QDL_PAD_DISP0_DAT2__ECSPI3_MISO 0x0b0b1

  MX6QDL_PAD_DISP0_DAT1__ECSPI3_MOSI 0x0b0b1

  MX6QDL_PAD_DISP0_DAT0__ECSPI3_SCLK 0x0b0b1

  MX6QDL_PAD_DISP0_DAT3__ECSPI3_SS0 0x0b0b1

  >;

};

 

What is possible case for SPI SCLK is not generated?

 

 

Thanks

Saurabh
