修改相关源文件

psplash-config.h

/* Text to output on program start; if undefined, output nothing */
#define PSPLASH_STARTUP_MSG ""

/* Bool indicating if the image is fullscreen, as opposed to split screen */
#define PSPLASH_IMG_FULLSCREEN 0

/* Position of the image split from top edge, numerator of fraction */
//图像的位置从上边缘分割，分数的分子
#define PSPLASH_IMG_SPLIT_NUMERATOR 5

/* Position of the image split from top edge, denominator of fraction */
//图像的位置从顶部边缘分割，分数的分母
#define PSPLASH_IMG_SPLIT_DENOMINATOR 6

psplash-colors.h颜色配置文件（背景色 进度条颜色等）

/* This is the overall background color */
#define PSPLASH_BACKGROUND_COLOR 0x00,0x00,0x00 //背景色rgb值

/* This is the color of any text output */
#define PSPLASH_TEXT_COLOR 0xFF,0xFF,0xFF//文本内容

/* This is the color of the progress bar indicator */
#define PSPLASH_BAR_COLOR 0xff,0x00,0x00 //进度条颜色
/* This is the color of the progress bar background */
#define PSPLASH_BAR_BACKGROUND_COLOR 0x00,0x00,0x00//进度条背景颜色

设置进度条 高度宽度 psplash_draw_progress（psplash.c）函数中

  /* 4 pix border */ //bar.png的(上下左右)边界到进度条区间隔4pix，如果间隔改了，此处应做修改.
  x      = ((fb->width  - BAR_IMG_WIDTH)/2) + 4 ;
  y      = SPLIT_LINE_POS(fb) + 4;
  width  = BAR_IMG_WIDTH - 8; 
  height = BAR_IMG_HEIGHT - 8;

设置LOGO 进度条的坐标

/* Text to output on program start; if undefined, output nothing */
#define PSPLASH_STARTUP_MSG ""  //文本信息

/* Bool indicating if the image is fullscreen, as opposed to split screen */
#define PSPLASH_IMG_FULLSCREEN 1
//为0时：LOGO 居中
//为1时：LOGO 上部分屏居中（height*PSPLASH_IMG_SPLIT_NUMERATOR/PSPLASH_IMG_SPLIT_DENOMINATOR）
//屏分为上下两部分  上部分LOGO居中  下部分进度条居中     
/* Position of the image split from top edge, numerator of fraction */
#define PSPLASH_IMG_SPLIT_NUMERATOR 5

/* Position of the image split from top edge, denominator of fraction */
#define PSPLASH_IMG_SPLIT_DENOMINATOR 6

生成Makefile 运行#./autogen.sh

#!/bin/bash
aclocal
autoheader
automake --add-missing
autoconf

#./configure --host=arm-linux CC=arm-linux-gnueabihf-g #设置交叉编译库

#./make-image-header.sh base-images/bar.png BAR #会生成bar-img.h 

#copy bar-img.h  psplash-bar-img.h

#./make-image-header.sh base-images/logo.png POKY#会生成logo-img.h

#copy logo-img.h  psplash-poky-img.h 
//或者psplash.c中 将#include "psplash-poky-img.h" 替换为#include "logo-img.h"

#make

最后将psplash复制到/usr/bin/psplash 若修改了psplash也要做相应覆盖
