最近我往TQ2440上移植了uboot-v2，好不容易kernel起来了，却又碰到了Warning: unable to open an initial console.我使用的文件系统和kernel都是天嵌提供的，kernel也就改了一下nandflash分区，为的的是和uboot里的分区设置一致，nandflash分区设置：nand_parts="256k(uboot),128k(ubootenv),4096k(kernel),-(rootfs)" uboot启动参数："noinitrd console=ttySAC0 root=/dev/mtdblock3 init=/linuxrc"
