今天想试着改变开发板的logo，但是问题多多

今天试着改变logo,先在我自己的电脑里找到一个png格式的图片，折腾很久 正常 ，的确把logo改啦，但是在LCD上显示的很小，只在屏幕左上角显示，我想实现整屏的显示，就自己随便用QQ截图得到一个png格式的图片，生成xxx.ppm个时候替换了内核自带的logo_linux_tft480272_clut224.ppm，然后编译
出问题啦
<stdin>:1265:2: warning: #warning syscall migrate_pages not implemented
<stdin>:1321:2: warning: #warning syscall pselect6 not implemented

  CHK     include/linux/compile.h
  LOGO    drivers/video/logo/logo_linux_tft480272_clut224.c
Image has more than 224 colors
Use ppmquant(1) to reduce the number of colors

make[2]: *** [drivers/video/logo] Error 2

make: *** [drivers] Error 2
提示超过224位，刚开始以为是大小问题，把图片尺寸截的很小 再说，

制作ppm文件时有如下提示
a123@a123-virtual-machine:~/lx/picture$ cp /mnt/hgfs/Ub/QQ.png .
a123@a123-virtual-machine:~/lx/picture$ pngtopnm QQ.png >QQ.pnm

pnmcolormap: 9066 colors found
pnmcolormap: choosing 244 colors...

a123@a123-virtual-machine:~/lx/picture$

生成ppm格式文件替换
logo_linux_tft480272_clut224.ppm文件编译后还是出错

这个怎么回事，怎么样实现任意图片都能显示在LCD屏上，
对图片的格式和大学有什么要求，求大神

亲，我只能说你手册没看仔细！！

我参考的是天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf这个文档，其他还有哪个文档吗?
请明示
