求解啊：这是我下载内核和文件用的命令：
tftp 0x30008000 uImage
nand erase 0x50000 0x200000
nand write 0x30008000 0x50000 0x200000
tftp 0x30008000 rootfs_qtopia_qt4.img
nand erase 0x250000 0x3db0000
nand write.yaffs2 0x30008000 0x250000 $(filesize
不知道哪里出了问题啊，求大大门指点啊，急急急

uboot设置的环境变量：bootargs=noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0,115200 rootf
stype=yaffs2 rw mem=64M
bootcmd=nand read 0x30008000 0x50000 0x200000; bootm 0x30008000
bootdelay=1

请问下：
bootargs=noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0,115200 rootf
stype=yaffs2 rw mem=64M

中的 root=/dev/mtdblock3 console=ttySAC0 是根据 什么来的呢？
