首先，小弟本来打算用mini2440 光盘自带的ucos，但是通过u-boot的down and run 后 无法正常运行，重启u-boot。
因此小弟只有从网上下载一款伟研科技的 ucos2，它是修改了u-boot的中断跳转：*（unsigned *）0x34=..IRQ.可以正常运行。
问题1：mini2440的ucos，因怎么修改，小弟自己也稍微在main函数里面：*（unsigned *）0x34=OS_CPU_IRQ_ISR，还是重启u-boot。
接下来关于yaffs的移植，我从pudn上下载一个yaffs针对ucos的源代码。网址：
http://www.pudn.com/downloads56/sourcecode/embed/detail196250.html修改关于nandflash的 read write erase 和init。还有就是yaffs_lock unlock local init.发现程序无法正常运行。通过打印输出显示：发现无法成功执行yaffs_mount.再深入就是程序停止了yaffs_scan();有谁知道为什么啊？？？？希望高手指点！！！！在ads编译中会出现关于位域的错误：struct yaffs_ObjectStruct{__u8 deleted: 1; ........。。。。。。。。。
