我重新编译了skyeye, 使用testsuite2/s3c2410/下的文件测试,启动后提示
/bin/ash: can't access tty; job control turned off,之后就不能输入任何命令了。
查询了google:
I guess you run it like this:ash </dev/console >/dev/console 2>&1
but /dev/console is a bit special: it cannot be a *controlling tty*. If ash parent has no ctty, ash wouldn't have ctty too and therefore will be unable to use keyboard signals.
