为了更好的调试，决定采取tftp的方式下载内核和根文件系统，于是首先设置环境变量如下：
OMAP3 DevKit8000 # printenv
bootargs=console=ttyS2,115200n8 ubi.mtd=4 root=ubi0:rootfs rootfstype=ubifs video=omapfb:mode:4.3inch_LCD

bootfile="uImage"

bootcmd=run tftp0;run tftp1;run tftp2;run tftp3
tftp0=setenv bootargs console=ttyS2,115200n8 mem=128M init=0x81000000,7000000 root=/dev/ram0 rw
stdin=serial
stdout=serial
stderr=serial
Environment size: 532/131068 bytes
本意是把内核下载到0x80300000,根文件系统下载到0x81000000，然后运行。
但是启动时报错了，启动过程如下：

提示找不到根文件系统。
直接把根文件系统拷贝到SDRAM，再运行应该是没有问题的，莫非我的写法有误？
于是重新设置
setenv tftp0 setenv bootargs console=ttyS2,115200n8 root=/dev/ram0 initrd=0x81100000,32M
saveenv
重新启动，还是失败。
可能只能采用ramdisk镜像了，于是换成ramdisk的根文件系统

启动成功。
我用at91sam9260时是可以直接把根文件系统（不管什么格式）拷贝到SDRAM，然后从ram0里运行的，是没有任何问题的。
用OMAP3530却不行（至少在我手上不行），做个标记，等后续再弄。
