I have modified the boot arguments as below
setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 consoleblank=0 init=/init video=mxcfb2:dev=lcd,CLAA-WVGA@60,bpp=32,if=RGB24 video=mxcfb1:off video=mxcfb0:off video=mxcfb3:off vmalloc=400M androidboot.hardware=freescale cma=384M mtdparts=gpmi-nand:16m(bootloader),16m(bootimg),16m(recovery),-(root) ubi.mtd=4
and modified a little bit in imx6qdl-sabresd.dtsi
mxcfb3: fb@2 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "lcd";
interface_pix_fmt = "RGB24";
mode_str ="CLAA-WVGA";
default_bpp = <16>;
int_clk = <0>;
late_init = <0>;
status = "disabled";
};
lcd@0 {
compatible = "fsl,lcd";
ipu_id = <0>;
disp_id = <0>;
default_ifmt = "RGB24";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ipu1_1>;
status = "okay";
};
However, no signal is output on VSYNCH, HSYNCH & DISP0_CLK. Please kindly advise. Below is my debug print message, lcdif_probe & lcdif_init have been entered.
