I am ending up in the shell prompt with the message as below: "entered linuxrc script" "/bin/sh: can't access tty; job control turned off / $" my kernel commad line is "mem=32M console=ttySAC0,115200 root=/dev/ram0 init=/linuxrc initrd= 0x80800000,8M user_debug=31"
In my kernel command line(with busybox), init=/sbin/init, I drop commands into /etc/profile.
Below are my /linuxrc and /etc/inittab file contents linuxrc: #!/bin/sh /bin/echo "entered linuxrc script" /bin/sh exec /sbin/init
Don't run sh before init, this makes the warning.
/etc/inittab: # Run gettys in standard runlevels 3:2345:respawn:/sbin/getty 115200 ttySAC0
runlevels makes no sense here, but it should be OK. And, I use busybox to build the rootfs for kernel debugging: https://github.com/adam8157/kernel-studio the rootfs making script is at here right now: https://github.com/adam8157/kernel-studio/blob/master/mkrootfs Might helps. -- Regards, Adam Lee -------------------------------- E-mail: adam8157 at gmail.com Website: http://adam8157.info --------------------------------
