Hi all,

 

We are using imx6q processor with TM050RVHG01-00 LCD and using kernel version : 3.14.28 .

 

We have following issue.

1. After booting system, if we run LCD preview then it is correct as you find in attachment.

2. After booting system, first we run HDMI preview and then LCD preview then LCD preview gets corrupted. This corrupted also found in attachment.

3. After booting system, if we start both LCD and HDMI preview together then also we face same issue.

 

Following is the device tree of our product. we are using mxcfb1 for LCD and mxcfb2 for HDMI. Let us know if we are missing anything to configure IPU.

        mxcfb1: fb@0 {
                compatible = "fsl,mxc_sdc_fb";
                disp_dev = "lcd";
                interface_pix_fmt = "RGB24";
                mode_str ="TM050RVHG01-00";
                default_bpp = <24>;
                int_clk = <0>;
                late_init = <0>;
                status = "okay";
        };

 

        mxcfb2: fb@1 {
                compatible = "fsl,mxc_sdc_fb";
                disp_dev = "hdmi";
                interface_pix_fmt = "RGB24";
                mode_str ="1920x1080M@60";
                default_bpp = <32>;
                int_clk = <0>;
                late_init = <0>;
                status = "okay";
        };

 

We are using standard V4L2 base application to get preview on LCD and HDMI. So let us know if you need application source code.

 

Thanks,
