Here is the environment of my project:

android:4.4.2

kernel:3.0.35

we only show logo in the kernel instead of uboot,the way showing logo is that:

1.change logo image to logo_linux_clut224.ppm;

2.delete the old logo_linux_clut224.ppm,logo_linux_clut224.c and logo_linux_clut224.o files in drivers/video/logo/ category;

3.place the logo_linux_clut224.ppm file in the first step to drivers/video/logo;

4.open CONFIG_LOGO_BLACKFIN_CLUT224 and CONFIG_LOGO config;

5.CONFIG_MX6_CLK_FOR_BOOTUI_TRANS is "N".

but we have a problem. Sometimes, when starting kernel, we found that our logo would flick across the screen,so anyone can help me solve the problem?Thanks.
