u-boot-2010.09 For FL2440 board

dglwx

去年12月份完成了FL2440的移植工作(花了一个月的时间),包括:
  自己制作交叉编译器(Buildroot 2010.11),
  最新的u-boot-2010.09,
  Linux内核2.6.33(为了跟公司的产品的内核保持一致)
  移植了USB wifi驱动,开发板可以使用WiFi上网,准备移植AP的驱动,将2440做一个无线路由器;
  完成触摸屏驱动,以前在2410上完成了tslib的移植,成功移植miniGUI(开源的最新版本),mplayer(可以播放MP3,MP4),完成桌面版最新的QT移植(但界面没跑起来,很遗憾,下一步再跑起来.)

  下一阶段准备开发GPRS模块,使用GTM900B或SIM900B,同事准备3G模块的开发,在其它平台上完成了GPRS模块拨号上网,收发短信的功能.这部分移植到fl2440平台上也非常容易.

  目前项目还在推进当中,在项目中跟上实践最能学到东西,有想跟进我的项目可以和我联系(QQ: 281143292(加友请注明来自fl2440论坛), Email:  guowenxue@gmail.com).  有武汉的同学,可以和我联系,嵌入式开发项目实战辅导,ARM7(W90P710)+uClinux, ARM9(S3C2440+AT91SAM9260两个平台)+Linux,  51单片机系列等等.从原理图,PCB设计,到底层汇编,内核驱动,系统移植,上层应用程序编写.


下面的u-boot使用J-link烧录到nandflash上.

    附件中是patch包啊，到官方下了u-boot-2010.09后，打上patch包就是源码了。

    认真看看patch文件和2010.09的u-boot架构! 你make fl2440_config && make 看看,不过要先在Makefile里修改成你的交叉编译器(如果环境变量里没有导出你默认使用的交叉编译器的话).

不错
