u-boot command:
setenv mmcargs setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} ${bootargs} video=mxcfb0:dev=ldb,1024x768M@60,if=RGB24 video=mxcfb1:off video=mxcfb2:off
LVDS resolution can not be dynamically adjusted correctly on Yocto 3.14.28_1.0.0.
But it is worked fine on Yocto 3.10.17_1.0.0.
Yocto 3.10.17_1.0.0 dts file:
mxcfb3: fb@2 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "ldb";
interface_pix_fmt = "RGB24";
mode_str ="800x480M@60";
default_bpp = <16>;
int_clk = <0>;
late_init = <0>;
status = "disabled";
};
&ldb {
ipu_id = <1>;
disp_id = <0>;
ext_ref = <1>;
mode = "sep0";
sec_ipu_id = <0>;
sec_disp_id = <1>;
status = "disabled";
};

vback-porch = <3>;

};
};
};
};
Can you tell me how to solve this issue?
Thank you.
