Subject: RE: Warning: unable to open an initial console.

I checked /dev/ with U-boot and it shows the existence of /dev/console.

>From U-boot prompt:

$ ls /dev
 crw-------        0 Mon Apr 02 17:52:27 2007 console
 crw-r--r--        0 Mon Apr 02 17:52:27 2007 null
 crw-r--r--        0 Mon Apr 02 17:52:27 2007 zero

Also, I added a printk in the jffs2_add_fd_to_list() routine in
fs/jffs2/nodelist.c to print out the dirent adds and it shows console
being added as follows:

...
add dirent "var", ino #14
add dirent "usr", ino #13
add dirent "tmp", ino #12
add dirent "sys", ino #11
add dirent "sbin", ino #10
add dirent "proc", ino #9
add dirent "mnt", ino #8
add dirent "linuxrc", ino #7
add dirent "lib", ino #6
add dirent "home", ino #5
add dirent "etc", ino #4
add dirent "dev", ino #3
add dirent "bin", ino #2
VFS: Mounted root (jffs2 filesystem).
Freeing init memory: 76K
add dirent "zero", ino #70
add dirent "null", ino #69
add dirent "console", ino #68
Warning: unable to open an initial console.
add dirent "watchdog", ino #262
add dirent "udevstart", ino #261
add dirent "udevsend", ino #260
...

Any other ideas?
Thanks,
Tom

your rootfs/initramfs/initrd is missing a valid working /dev/console

check /dev/ on this filesystem
