最簡單的替換方法是重新編譯 psplash，對應目錄在 meta-yocto/recipes-core/psplash。如果沒有該目錄的話，就需要下載，下載方法如下：

root@bogon:/yocto/sources/meta-fsl-arm/recipes-core# git clone git://git.yoctoproject.org/psplash

•  

出現如下提示則表示下載成功：

檢視是否下載成功：

root@bogon:/yocto/sources/meta-fsl-arm/recipes-core# ls

packagegroup  psplash  udev

進入 psplash 目錄，檢視具體檔案：

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 標頭檔案：

root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# ./make-image-header.sh /home/rudy/Desktop/

.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

再次檢視：

root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# ls

修改 psplash.c 檔案：

root@bogon:/yocto/sources/meta-fsl-arm/recipes-core/psplash# vim psplash.c

•  

新增 #include "tux-img.h"，重新編譯再替換 /usr/bin/psplash 即可。
