最简单的替换方法是重新编译 psplash，对应目录在 meta-yocto/recipes-core/psplash。如果没有该目录的话，就需要下载，下载方法如下：
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core# git clone git://git.yoctoproject.org/psplash
出现如下提示则表示下载成功：

查看是否下载成功：
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core# ls
进入 psplash 目录，查看具体文件：
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core# cd psplash/
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# ls

生成 logo 头文件：

.directory tux.png tux-p.png
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# ./make-image-header.sh /home/rudy/Desktop/tux.png POKY
再次查看：
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# ls
AUTHORS configure.ac Makefile.am psplash-bar-img.h psplash-config.h psplash.doap psplash.h psplash-write.c

修改 psplash.c 文件：
root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# vim psplash.c
添加 #include "tux-img.h"，重新编译再替换 /usr/bin/psplash 即可。
