Dear NXP,

               我使用的是i.mx6 sabresd_6dq  系统是android6.0 内核是4.1.15.

现在想把uboot和内核的bootlogo更换为自己的启动画面。查看下面链接Patch to support uboot logo keep from uboot to kernel for NXP Linux and Android BSP (HDMI, LCD and LVDS) 

使用的是M6.0.1_2.1.0_uboot_logo_keep_patch_2017-01-06.zip

根据readme打好patch,但是有以下疑问,还请帮忙解答:

问题一、我使用make menuconfig查看、无下面选项

Before "make zImage KCFLAGS=-mno-android", make menuconfig can be used to select the display type.
System Type --->
Freescale MXC Implementations --->
MX6 clk setting for smooth UI transtion from bootloader to kernel --->
/
( ) Smooth UI transtion on LCD, IPU1, DI0
( ) Smooth UI transtion on LVDS, IPU1, DI0
( ) Smooth UI transtion on LVDS, IPU1, DI1
( ) Smooth UI transtion on LVDS, IPU2, DI1
( ) Smooth UI transtion on HDMI, IPU1, DI0
(X) Smooth UI transtion on HDMI, IPU2,

是否有影响?

 

问题二:

         假设上面问题无影响。我使用的是emmc启动,自己的logo.bmp  push到系统中后,

需要将它dd到那个具体分区才能替换掉uboot和内核之前的bootlogo.

-- dd the logo.bmp to SD card address 0x100000 and skip the 54 bytes bmp file header.
sudo dd if=logo.bmp of=/dev/sdc bs=1 seek=1048576 skip=54

下面是系统中的分区表

 

 

非常感谢你们的帮忙!!!
