一、移植环境

主  机：VMWare--Fedora 9
开发板：Mini2440--64MB Nand
编译器：arm-linux-gcc-4.3.2
二、移植步骤

1. 配置内核对USB设备的支持。2.6.30.4内核中对USB设备的支持已经非常全面了，这里只需要配置他就可以了，配置完后重新编译内核烧到开发板上

SCSI device support --->
      < > RAID Transport Class
      <*> SCSI device support
      < > SCSI target support
      [*] legacy /proc/scsi/ support
      *** SCSI support type (disk, tape, CD-ROM) ***
      <*> SCSI disk support
      < > SCSI tape support
      < > SCSI OnStream SC-x0 tape support
      < > SCSI CDROM support
      <*> SCSI generic support
      < > SCSI media changer support
[*] HID Devices --->
      --- HID Devices
      -*- Generic HID support
      [ ] HID debugging support
      [ ] /dev/hidraw raw HID device support
      *** USB Input Devices ***
      <*> USB Human Interface Device (full HID) support
      [ ] PID device support
      [*] /dev/hiddev raw HID device support
[*] USB support --->
      {*} Support for Host-side USB
      [ ] USB verbose debug messages
      [ ] USB announce new devices
      *** Miscellaneous USB options ***
      [*] USB device filesystem
      [*] USB device class-devices (DEPRECATED)
      <*> OHCI HCD support
      <*> USB Mass Storage support

2. 插入U盘。当系统启动后插入U盘就会出现一些信息，可以看到sda就是U盘设备了，sda1是U盘的一个分区

3. 挂载U盘。执行mount命令将U盘挂载到/mnt/usb/目录下，但是没成功，出错啦

3. 错误分析处理。首先查看/dev/目录下并没有sda1节点所以出错，我们查看/proc/partitions/目录发现sda1的主设备号是8，次设备号是1，那么我们就创建这个设备的节点，b代表块设备，最后再执行mount命令，没有出错

4. U盘成功挂载。查看U盘中的内容

一、移植环境

主  机：VMWare--Fedora 9
开发板：Mini2440--64MB Nand
编译器：arm-linux-gcc-4.3.2
二、移植步骤

1. 修改内核源码。2.6.30.4内核对LCD的支持已很完善，这里只做少许修改 #gedit arch/arm/mach-s3c2440/mach-smdk2440.c

修改smdk2440_lcd_cfg函数和smdk2440_fb_info函数，设置LCD参数，我的是NEC3.5寸TFT屏。如下：

打开LCD的背光，如不打开就无法观测LCD是否正常工作。由开发板原理图可以看到LCD的背光电源LCD_PWR接到S3C2440的GPG4引脚上，故作如下修改

2. 配置内核选项。选上LCD支持和Logo图标

Device Drivers --->
Graphics support --->
      < > Lowlevel video output switch controls
      <*> Support for frame buffer devices --->
         --- Support for frame buffer devices
         [*] Enable firmware EDID
         [ ] Framebuffer foreign endianness support --->
         [*] Enable Video Mode Handling Helpers
         [ ] Enable Tile Blitting Support
         *** Frame buffer hardware drivers ***
         < > Epson S1D13XXX framebuffer support
         <*> S3C2410 LCD framebuffer support
         [ ] S3C2410 lcd debug messages
         < > Silicon Motion SM501 framebuffer support
         < > Virtual Frame Buffer support (ONLY FOR TESTING!)
         < > E-Ink Metronome/8track controller support
         < > Fujitsu MB862xx GDC support
         < > E-Ink Broadsheet/Epson S1D13521 controller support
      [*] Backlight & LCD device support --->
         Display device support --->
         Console display driver support --->
      [*] Bootup logo --->
         --- Bootup logo
         [ ] Standard black and white Linux logo
         [ ] Standard 16-color Linux logo
         [*] Standard 224-color Linux logo (NEW)

3. 重新编译内核并下载到开发板上，上电系统启动后可以看到LCD亮起，并且出现小企鹅图标。
