用busybox自制文件系统, 在android kernel下启动, 无法正常启动
如题, 用busybox自制文件系统, 在android kernel下启动, 无法正常启动BOOT参数如下:root=/dev/mtdblock2 rootfstype=yaffs2 init=/linuxrc console=ttySAC0,115200
出现以下错误:
yaffs: dev is 32505858 name is "mtdblock2"
yaffs: passed flags ""
yaffs: Attempting MTD mount on 31.2, "mtdblock2"
yaffs_read_super: isCheckpointed 0
VFS: Mounted root (yaffs2 filesystem) on device 31:2.
Freeing init memory: 140K
Warning: unable to open an initial console.
按照网上帖子的常用解决方法,
mknod -m 660 console c 5 1
mknod -m 660 null c 1 3
重新创建/dev/console /dev/null , 错误依旧.
文件系统配置如下:
.:
bindevetcinitliblinuxrcmntprocrootsbinsystmpusr
./bin:
addgroupdeluser hostnamelsattr pipe_progressstty
adduser df hush lzop printenv su
ash dmesg ionice makemime ps sync

修改启动参数, 故意将root指向mtdblock3,则报出不一样的错误
yaffs: dev is 32505859 name is "mtdblock3"
yaffs: passed flags ""
yaffs: Attempting MTD mount on 31.3, "mtdblock3"
yaffs_read_super: isCheckpointed 0
VFS: Mounted root (yaffs2 filesystem) on device 31:3.
Freeing init memory: 140K
Warning: unable to open an initial console.
Failed to execute linuxrc.Attempting defaults...
Kernel panic - not syncing: No init found.Try passing init= option to kernel.
对比上面的错误看, root指向mtdblock2时,init操作没有报错,好像是yaffs文件系统 已经被正确的识别了, 本人菜鸟 , 不确定, 还请大虾指教.
如果yaffs文件系统 被识别了, 我又多次重新mknod /dev/console /dev/null, 为什么还是报Warning: unable to open an initial console.的错误呢? console， mknod的时候参数是什么？
另外看一下boot传给kernel的参数
