Hi,<br>I am newbie to linux kernel,doing kernel porting on a arm926ej-s
FPGA board (only timer & uart hardware is available in the board)<br><br>I'm using busybox for rootfs(busy box binary is built with "static" option enabled)<br>
<br>After file system is mounted,I can see the below message, <br>"VFS: Mounted root (cramfs filesystem) readonly on device 1:0."<br>"Freeing init memory: 80K"<br><br>I am expecting to get to shell prompt and give some commands (ls,clear) after file system gets mounted. <br>
<br><b>I am ending up in the shell prompt with the message as below:</b><br>"entered linuxrc script"<br>"/bin/sh: can't access tty; job control turned off<br>/ $"<br><br>I am getting no response from terminal for any commands entered in the shel lafter this.<br>
<br>I went through this FAQ in<a href="http://www.busybox.net/FAQ.html#job_control" target="_blank"> http://www.busybox.net/FAQ.html#job_control</a><br>I could not follow this exactly.<br><br>my kernel commad line is <br>
"mem=32M console=ttySAC0,115200 root=/dev/ram0 init=/linuxrc initrd=0x80800000,8M user_debug=31"<br>
<br><br><b>I could see 2 issues here:</b><br>1. I am using shell on /dev/console which is not correct as mentioned in busybox FAQ<br>2. linuxrc and /etc/inittab files may not be correct.<br><br>I think the problem could be in both above 2 cases.<br>
<br><br>Below are my /linuxrc and /etc/inittab file contents<br><b>linuxrc:<br><br></b>#!/bin/sh<br>/bin/echo "entered linuxrc script"<br>/bin/sh<br>exec /sbin/init<br><br><b><br>/etc/inittab:</b><br><br>id:3:initdefault:<br>
