1 开启uClinux的FrameBuffer支持
1.1 修改 /uClinux-dist/vendors/Samsung/44B0/config.linux-2.4.x
确定 CONFIG_VT=y    //VT 应该是Virtual Terminal
1.2 修改/uClinux-dist/linux-2.4.x/drivers/video/s3c44b0xfb.c
默认情况下是支持16灰度屏的，如果是256色屏，则需要将#define    LCD_GRAY_16 注释掉。
1.3 增加fb0设备
修改vendors/Samsung/44B0/Makefile
1.4 驱动确定
linux-2.4.x/drivers/video/Config.in
if [ "$CONFIG_CPU_S3C44B0X" = "y" ]; then
      tristate ' Samsung S3C44B0X built-in LCD controller frame buffer support' CONFIG_FB_S3C44B0X
fi
linux-2.4.x/drivers/video/Makefile
obj-$(CONFIG_FB_S3C44B0X)          +=s3c44b0xfb.o
linux-2.4.x/drivers/video/fbmem.c
extern int s3c44b0xfb_init(void);
extern int s3c44b0xfb_setup(void);
 
#ifdef CONFIG_FB_S3C44B0X
         {“s3c44b0xfb”,s3c440xfb_init,s3c44b0xfb_setup},
#endif
DEVICES = /
         fb0,c,29,0
1.5 编译uClinux

*********************************************************************************/
因为LCD是256色的，所以选择下项
8 bpp packed pixels support (CONFIG_FBCON_CFB8) [N/y/?] (NEW) y
如果下载内核后进不去系统，则Virtual Terminal 不选，如果进去后fb0不能用，则要选，因为不选的话会屏蔽Support Frame buffer devices (CONFIG_FB) [N/y/?] (NEW) y的设置，Virtual Terminal 意思是超级终端显示的数据在LCD上显示，同时超级终端也显示。
1.6 测试/dev/fb0
1）测度程序 test1.c
测试/dev/fb0 有没存在，以及其属性
/*******************************************************************************
#include <linux/fb.h>
#include <unistd.h>
#include <sys/mman.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
 
int main ()
{
int fp=0;
struct fb_var_screeninfo vinfo;
struct fb_fix_screeninfo finfo;
fp = open ("/dev/fb0",O_RDWR);
 
if (fp < 0){
printf("Error : Can not open framebuffer device/n");
return 0;
}
 
if (ioctl(fp,FBIOGET_FSCREENINFO,&finfo)){
printf("Error reading fixed information/n");
return 0;
}
 
if (ioctl(fp,FBIOGET_VSCREENINFO,&vinfo)){
printf("Error reading variable information/n");
return 0;
}
 
printf("The mem is :%d/n",finfo.smem_len);
printf("The line_length is :%d/n",finfo.line_length);
printf("The xres is :%d/n",vinfo.xres);
printf("The yres is :%d/n",vinfo.yres);
printf("bits_per_pixel is :%d/n",vinfo.bits_per_pixel);
close (fp);
return 0;
}
*******************************************************************************/
2) 测试程序test2.c
在LCD上显示一张图片
/**********************************************************************************

#include <unistd.h>
#include <sys/mman.h>
#include <sys/types.h>

const unsigned char gImage_bmp[76560]={……}
//该数组可能过Image2LCD软件生成，该软件可在www.baidu.com找到
int main()
{
 int framebuffer_device;
 int line_size,buffer_size,i;
 char *screen_memory;
 struct fb_var_screeninfo var_info;
 struct fb_fix_screeninfo fix_info;
 
 framebuffer_device=open("/dev/fb0",O_RDWR);
 ioctl(framebuffer_device,FBIOGET_VSCREENINFO,&var_info);
 ioctl(framebuffer_device,FBIOGET_FSCREENINFO,&fix_info);
 line_size=var_info.xres*var_info.bits_per_pixel/8;
 buffer_size=line_size*var_info.yres;
 var_info.xoffset=0;
 var_info.yoffset=0;
 
 screen_memory=(char*)mmap(0,buffer_size,PROT_READ|PROT_WRITE,0,framebuffer_device,0);
 for(i=0;i<buffer_size;i++)
 {
    *(screen_memory+i)=gImage_bmp[i];
 }
 sleep(2);
 return 0;
}
**********************************************************************************/
3) 将程序编译进内核
uClinux-dist/romfs/ 里的文件是最终生成的内核文件，也是开发板上系统能看到的文件，要将文件编译进内核，只需把文件放到这里就行，然后make
arm-elf-gcc –elf2flt –o test1 test1.c
arm-elf-gcc –elf2flt –o test2 test.c
将test1 test2 放到uClinux-dist/romfs/usr/里
Make 两次,我发现make一次没装进去。
内核编译后下载进开发板，进入系统,运行程序就可测出/dev/fb0有没存在，FrameBuffer有没配置成功。
2 minigui移植
2.1 安装库和资源
1） 解压 minigui-res-1.6.tar.gz , 设置config.linux文件，将编译器设置为arm-elf-gcc。并将安装路径设置为arm-elf-gcc所在的目录。
tar –zxvf minigui-res-1.6.tar.gz
修改config.linux
prefix = $(TOPDIR)/usr/local/
CC     = arm-elf-gcc
然后
Make install
安装到/usr/local/lib/minigui/res
该res 是MiniGUI.cfg 里面资源引用的位置，也是进行移植的资源。
prefix = $(TOPDIR)/usr/local/arm-elf
CC     = arm-elf-gcc
然后
Make install
安装到/usr/local/arm-elf/lib/minigui/res 编译器库里的资源
2） 解压 libminigui-1.6.x-linux.tar.gz, 修改编译参数
tar –zxvf libminigui-1.6.x-linux.tar.gz
修改 libminigui-1.6.2-linux/scripts/mkconfig
if check_value "CONFIG_COMPILER_ARM_ELF"; then
   # CFLAGS="$CFLAGS -D__PIC__ -fpic -msingle-pic-base"
     CFLAGS="$CFLAGS -D__PIC__ -fno-pic -fno-PIC"
Fi
不然在开发板运行程序时会出现如下错误码：
Unhandled fault:external abort on linefetch (F4) at 0x00000001
Fault-common.c(97):start_code=0xc2b9ca0,start_stack=0xc63ff98)
Pid 28:failed 7

2.2 移植配置文件和资源

1) 配置文件 MiniGUI.cfg

配置文件的名称必需是MiniGUI.cfg，放在/etc/ 下。

由于DRAM的大小限制，我对MiniGUI的资源进行了裁减，主要是字体部分。fbcon 表示采用Framebuffer，dummy表示没有输入设备，如触摸屏。

[varbitmapfonts]

font_number=0

表示没有varbitmapfonts，会忽略该字段下的资源引用。
