系统用的yocto，内核版本3.14.28，lcd可以正常显示，但是vga下显示模糊，lcd用的是rgb565,vga用的是rgb24。
设备树：
mxcfb1: fb@0 {
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>;
status = "okay";
};
mxc_lcdif.c文件设置：
static struct fb_videomode lcdif_modedb[] = {
{
/* 800x480 @ 57 Hz , pixel clk @ 27MHz */
"CLAA-WVGA", 60, 800, 480, 37037, 40, 60, 10, 10, 20, 10,
FB_SYNC_CLK_LAT_FALL,
FB_VMODE_NONINTERLACED,
0,},
};
请问怎么修改才能让vga显示清楚，谢谢 |
