Hello everyone,

 

I'm trying to enable the MIPI display (DSI) on my board and I've encountered some problems.

I tried to modify the file imx6qdl-sabresd.dtsi and set the status of mxcfb3 and lcd to okay but it didn't work neither:

 

mxcfb3: fb@2 {

        compatible = "fsl,mxc_sdc_fb";

        disp_dev = "lcd";

        interface_pix_fmt = "RGB565";

        mode_str ="CLAA-WVGA";

        default_bpp = <16>;

        int_clk = <0>;

        late_init = <0>;

        status = "okay";

    };

 

lcd@0 {

        compatible = "fsl,lcd";

        ipu_id = <0>;

        disp_id = <0>;

        default_ifmt = "RGB565";

        pinctrl-names = "default";

        pinctrl-0 = <&pinctrl_ipu1_1>;

        status = "okay";

    };

 

I've got the following message when I'm booting the card with the image core-image-minimal:

 

mxc_mipi_dsi 21e0000.mipi: i.MX MIPI DSI driver probed

MIPI DSI driver module loaded

mxc_sdc_fb fb.32: register mxc display driver lcd

mxc_sdc_fb fb.32: ipu0-di0 already in use

mxc_sdc_fb: probe of fb.32 failed with error -16

 

I've also tried to change the disp_id of "&mipi_dsi" without success.

Anybody knows how to solve this?

 

Regards,

Antoine
