The initializing screen we mention here can be done by the psplash software package. With the image being coded directly into the file, it is required to recompile psplash software package if we need to change the background image. The steps are as follows: <1> Login to psplash software package directory. There’s a script named “make-image-header.sh”. If in the system there’s no gdk-pixbuf-csource command, you need to install libgtk2.0-dev. <2> Place a png format image under that directory, and rename it as psplash-poky.png. Back up psplash-poky-img.h. And then run "./make-image-header.sh psplash-poky.png POKY" <3> make <4> Copy new psplash package to Matrix's /usr/bin/.
