    };
};

按这个来配置，这个不行？

@晕哥  cp -r $YOUR_MOD_FILE  rootfs/lib/modules/    YOUR_MOD_FILE这个是什么文件？ 做启动文件系统需要用这个吗？

你是从git clone --depth=1 -b f1c100s-480272lcd-test https://github.com/Icenowy/linux.git
下载的吗

是的，没有

我的在这个目录下找不到，是不是我下载的LINUX有问题?

按上面打包，为什么我打包出来的bin文件有105M多呢？

我把 0:50000000 改成 "sf probe 0; " uboot可以正常启动了，请问F1C100S全套开发指南吗？再请问我们开发应用程序放在哪里编译，可不可以给一些实例模仿一下。

这是u-boot 启动信息，烧u-boot就可以看到串口有输出，SPIflash打包烧录串口一点信息就没有输出

就是按照二进制bin 打包
以16M 大小flash镜像打包脚本为例：
dd if=/dev/zero of=flashimg.bin bs=1M count=16 &&\
dd if=$YOUR_UBOOT_FILE of=flashimg.bin bs=1K conv=notrunc &&\
dd if=$YOUR_DTB_FILE of=flashimg.bin bs=1K seek=1024  conv=notrunc &&\
dd if=$YOUR_KERNEL_FILE of=flashimg.bin bs=1K seek=1088  conv=notrunc &&\
mkdir rootfs
tar -xzvf $YOUR_ROOTFS_FILE -C ./rootfs &&\
cp -r $YOUR_MOD_FILE  rootfs/lib/modules/ &&\
# 为根文件系统制作jffs2镜像包
# --pad参数指定 jffs2大小
# 由此计算得到 0x1000000(16M)-0x10000(64K)-0x100000(1M)-0x400000(4M)=0xAF0000
mkfs.jffs2 -s 0x100 -e 0x10000 --pad=0xAF0000 -d rootfs/ -o jffs2.img &&\
dd if=jffs2.img of=$YOUR_IMG_FILE  bs=1K seek=5184  conv=notrunc &&\生产启动文件，串口就没有输出

二进制bin 打包
以16M 大小flash镜像打包脚本为例：

dd if=/dev/zero of=flashimg.bin bs=1M count=16 &&\
dd if=$YOUR_UBOOT_FILE of=flashimg.bin bs=1K conv=notrunc &&\
dd if=$YOUR_DTB_FILE of=flashimg.bin bs=1K seek=1024  conv=notrunc &&\
dd if=$YOUR_KERNEL_FILE of=flashimg.bin bs=1K seek=1088  conv=notrunc &&\
mkdir rootfs
tar -xzvf $YOUR_ROOTFS_FILE -C ./rootfs &&\
cp -r $YOUR_MOD_FILE  rootfs/lib/modules/ &&\
# 为根文件系统制作jffs2镜像包
# --pad参数指定 jffs2大小
# 由此计算得到 0x1000000(16M)-0x10000(64K)-0x100000(1M)-0x400000(4M)=0xAF0000
mkfs.jffs2 -s 0x100 -e 0x10000 --pad=0xAF0000 -d rootfs/ -o jffs2.img &&\
dd if=jffs2.img of=$YOUR_IMG_FILE  bs=1K seek=5184  conv=notrunc &&\
以上脚本通过对一个生成的16M空bin文件填充 uboot、dtb、kernel、rootfs 生成 16M 镜像，如需修改，请注意各个文件的大小，修改成对应地址（注意对齐）。

怎么烧进FLASH 启动不了？

Linux下放在哪个目录？

不久把ucgui-3.90a移植到了Linux下，还是写个总结吧。。。

       ucgui的可移植性很高，只需要做很少的改动就可以移植到各个平台，移植到Linux下也一样。

       首先编辑GUIConf.h这个文件：

#ifndef GUICONF_H
#define GUICONF_H

#define GUI_OS    (1)                                          /* Compile with multitasking support */
#define GUI_SUPPORT_TOUCH     (0)                 /* Support a touch screen (req. win-manager), for linux */
#define GUI_SUPPORT_UNICODE     (1)              /* Support mixed ASCII/UNICODE strings, for linux */

#define GUI_DEFAULT_FONT     &GUI_Font6x8
#define GUI_ALLOC_SIZE     25*1024                  /* Size of dynamic memory */

#define GUI_SUPPORT_CURSOR        (1)                 /* for linux*/
         

#define GUI_WINSUPPORT     1                           /* Window manager package available */
#define GUI_SUPPORT_MEMDEV     1                 /* Memory devices available */
#define GUI_SUPPORT_AA     1                           /* Anti aliasing available */

#endif /* Avoid multiple inclusion */

     接着修改LCDConf.h文件，因为我们直接使用framebuffer设备，所以只需要修改LCDConf.h文件的前面部分即可：

#define LCD_XSIZE (720)                                    /* X-resolution of LCD, Logical coor. for linux */
#define LCD_YSIZE (576)                                    /* Y-resolution of LCD, Logical coor. for linux */

#define LCD_BITSPERPIXEL (16)                           /* for linux */

#define LCD_SWAP_RB    (1)                                    /* for linux, actually 1555 format */
#define LCD_FIXEDPALETTE    (555)                       /* for linux, actually 1555 format */
#define LCD_CONTROLLER (-1)                            /* for linux */

       接下来修改LCDDummy.c，添加对framebuffer的支持：

/* for linux framebuffer */

#include <unistd.h>
#include <stdio.h>
#include <fcntl.h>
#include <linux/fb.h>
#include <sys/mman.h>
#include <sys/ioctl.h>

static struct fb_var_screeninfo vinfo;
static struct fb_fix_screeninfo finfo;
static char *pFrameBuffer = NULL;

........................................................

void LCD_L0_SetPixelIndex(int x, int y, int PixelIndex)

{
      /* Convert logical into physical coordinates (Dep. on LCDConf.h) */
      #if LCD_SWAP_XY | LCD_MIRROR_X| LCD_MIRROR_Y
      int xPhys = LOG2PHYS_X(x, y);
      int yPhys = LOG2PHYS_Y(x, y);
      #else
      #define xPhys x
      #define yPhys y
      #endif

      int location = 0;
      location = (x + vinfo.xoffset) * (vinfo.bits_per_pixel >> 3) + (y+vinfo.yoffset) * finfo.line_length;
      *(short*)(pFrameBuffer + location) = (short)PixelIndex;    /* 16bpp */

      return;
}

unsigned int LCD_L0_GetPixelIndex(int x, int y)

{
      LCD_PIXELINDEX PixelIndex;
      /* Convert logical into physical coordinates (Dep. on LCDConf.h) */
      #if LCD_SWAP_XY | LCD_MIRROR_X| LCD_MIRROR_Y
      int xPhys = LOG2PHYS_X(x, y);
      int yPhys = LOG2PHYS_Y(x, y);
      #else
      #define xPhys x
      #define yPhys y
      #endif
      /* Read from hardware ... Adapt to your system */
     {
          int location = 0;
          location = (x + vinfo.xoffset) * (vinfo.bits_per_pixel >> 3) + (y+vinfo.yoffset) * finfo.line_length;
          PixelIndex = *(short*)(pFrameBuffer + location);    /* 16bpp */
      }
      return PixelIndex;
}

....................................................

int LCD_L0_Init(void)
{
     int f_fbDev;
     int ScreenSize;
     static struct fb_bitfield g_r16 = {10, 5, 0};
     static struct fb_bitfield g_g16 = {5, 5, 0};
     static struct fb_bitfield g_b16 = {0, 5, 0};
     static struct fb_bitfield g_a16 = {15, 1, 0};

     f_fbDev = open("/dev/fb0", O_RDWR);
     if (f_fbDev <= 0)
     {
           printf("Error: cannot open framebuffer device.\n");
           return (-1);
     }

     if (ioctl(f_fbDev, FBIOGET_VSCREENINFO, &vinfo) < 0)
    {
          printf("Error reading variable information.\n");
            close(f_fbDev);
          return (-1);
    }
    vinfo.xres = vinfo.xres_virtual = 720;
    vinfo.yres = 576;
     vinfo.yres_virtual = 576*2;

     vinfo.transp= g_a16;
     vinfo.red = g_r16;
     vinfo.green = g_g16;
     vinfo.blue = g_b16;
     vinfo.bits_per_pixel = 16;
     if (ioctl(f_fbDev, FBIOPUT_VSCREENINFO, &vinfo) < 0)
     {
            printf("Put variable screen info failed!\n");
            close(f_fbDev);
            return -1;
     }

     if (ioctl(f_fbDev, FBIOGET_FSCREENINFO, &finfo))
     {
           printf("Error reading fixed information.\n");
           return -1;
     }

     printf("xres is %d\n, yres is %d\n", vinfo.xres, vinfo.yres);
     ScreenSize = vinfo.xres * vinfo.yres * (vinfo.bits_per_pixel >> 3);

     pFrameBuffer =(char *)mmap(0, ScreenSize, PROT_READ | PROT_WRITE, MAP_SHARED,f_fbDev, 0);
     if ((long)pFrameBuffer == -1)
    {
           printf("Error: failed to map framebuffer device to memory.\n");
             close(f_fbDev);
           return (-1);
    }

    return 0;
}

     至此，LCDDummy.c修改完毕。

     接下来添加鼠标支持，新建一个GUI_MOUSE_DriverLinux.c代替原来的GUI_MOUSE_DriverPS2.c，这里的思路是用一个线程来读取鼠标设备：

.................................................

void *ThreadReamMouse(void)
{
     int ret;
     int fd;
     fd_set readfs;
     int maxfd = 0;
     char temp[3];

      fd = open ("/dev/mouse0",O_RDWR);
      if (fd < 0)
      {
               printf ("%s open failed\n", "/dev/mouse0");
               return NULL;
       }
       printf("open %s success, fd is %d\n", "/dev/mouse0", fd);

       maxfd = fd + 1; 
       for (; ;)
      {
                FD_ZERO(&readfs);
                FD_SET(fd, &readfs);
                ret = select(maxfd, &readfs, NULL, NULL, NULL);
                if (ret < 0)
               {
                      printf("select failure!\n");
                      return NULL;
               }

              if (FD_ISSET(fd, &readfs))
              {    
                         /*
                          * 读取鼠标
                          */
                        _NumBytesInBuffer = read(fd, _abInBuffer, sizeof(_abInBuffer));
                       if ((_NumBytesInBuffer == 3) && ((_abInBuffer[0] & 0x0c) == 0x08))
                       {
                               _EvaPacket();
                               //printf("Get mouse data!\n");
                        }
                }
     }
}

void GUI_MOUSE_DRIVER_PS2_Init(void)
{
           pthread_t pidReadMouse;

           _NumBytesInBuffer = 0;

           pthread_create(&pidReadMouse, NULL, (void *)ThreadReamMouse, NULL);
           printf("Create thread sucess!\n");
}

     GUI_MOUSE_DRIVER_PS2_Init()函数需要在哪里调用呢？不调用的话，鼠标没法用啊。增加GUI_X_Linux.c文件：

.............................................................

pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

..............................................................

void GUI_X_ExecIdle(void)
{
       usleep(1000);
       return;
}

int GUI_X_GetTime(void)
{
       struct timeval tv;
        int tm;
        gettimeofday(&tv, NULL);
        tm = tv.tv_sec*1024 + tv.tv_usec/1024;
   

       return tm;
}

void GUI_X_Delay(int Period)
{
       while(Period--)
      {
               usleep(1000);
       }
       return;
}

void GUI_X_Unlock(void)
{
        pthread_mutex_unlock(&mutex);
        return;
}
void GUI_X_Lock(void)
{
       pthread_mutex_lock(&mutex);
       return;
}
U32 GUI_X_GetTaskId(void)
{
       pthread_t id;

       id = pthread_self();
       printf("GUI_X_GetTaskId %d \n", (U32)id);
       return ((U32)id);
}
void GUI_X_InitOS(void)
{
       printf("GUI_X_InitOS\n");
       GUI_MOUSE_DRIVER_PS2_Init();                                 /* create read mouse thread for linux */
       return;
}
.....................................................

      至此，该修改的文件都修改完毕了，可以开始编译了。但是ucgui的工程一般是在windows下编译的，在Linux下交叉编译需要写Makefile，按照Linux的惯例，在每个文件夹下增加Makefile，如下：

CC = arm-linux-gcc
CFLAGS=-I../Core -I../../Config/ -I../WM/

#all c files at current directory
SRCS:=$(wildcard *.c)

#replace .c to .o in SRCS
OBJS:=$(SRCS:%.c=%.o)

all:$(OBJS)

%.o : %.c
         $(CC) $(CFLAGS) -c $< -o $@

.PHONY : clean

clean:
         rm *.o

     再增加一个编译gui库的Makefile：

SUBDIRS=AntiAlias ConvertMono Font LCDDriver MemDev Widget ConvertColor Core JPEG MultiLayer WM
LIBOBJS=
LIBOBJS+=$(wildcard AntiAlias/*.o)
LIBOBJS+=$(wildcard ConvertMono/*.o)
LIBOBJS+=$(wildcard Font/*.o)
LIBOBJS+=$(wildcard LCDDriver/*.o)
LIBOBJS+=$(wildcard MemDev/*.o)
LIBOBJS+=$(wildcard ConvertColor/*.o)
LIBOBJS+=$(wildcard Core/*.o)
LIBOBJS+=$(wildcard JPEG/*.o)
LIBOBJS+=$(wildcard MultiLayer/*.o)
LIBOBJS+=$(wildcard WM/*.o)
LIBOBJS+=$(wildcard Widget/*.o)

all:
         for name in $(SUBDIRS); do (cd $$name && make && cd ../) done
         make guilib

.PHONY:guilib

guilib:
         arm-linux-ar rv libucgui.a $(LIBOBJS)

.PHONY:clean   

clean:
         @rm -f libucgui.a
         @for name in $(SUBDIRS); do (cd $$name && make clean && cd ../) done

       至此，整个移植过程就告一段落，直接make 就可以了。。。
     
这样正确吗

请问ucGUI在NANO上用Linux移植，是怎么移植？
