Valid archive formats for initramfs include newc and crc. Method 3: Using a Configuration File This is the most flexible method. Mount your image from any other running Linux (for example Knoppix), mount the image as loop, and create this devices: # mknod -m 600 dev/console c 5 1 # mknod -m An external initramfs is employed in a manner that is similar with its initrd predecessor: CONFIG_BLK_DEV_INITRD need be enabled in the kernel.

Again, a dev node is missing. if [ "${mountstatus}" = "0" ]; then echo "Succeeded mounting ${root}" else echo "Failed to mount ${root}" return fi if [[ -x "${rootmnt}/${init}" ]]; then umount /sys /proc exec switch_root ${rootmnt} SourceForge About Site Status @sfnet_ops Powered by Apache Allura™ Find and Develop Software Create a Project Software Directory Top Downloaded Projects Community Blog @sourceforge Resources Help Site Documentation Support Request ©

Distributions use an initramfs as a way of maintaining a small generic kernel image - leaving the complexities that arise from the diversity of end-user system configurations/requirements to the initramfs. console file is not present in file system Jaacs Job Pottas 2013-08-16 18:00:44 Ok I solved the problem. These include issues such as mounting the final root filesystems which may be encrypted, across a network network (e.g. More drivers are involved in accessing the parallel Flash this way.

I'm hoping you'll beat me to it and find a solution!By the way, the Flash that we're using on our board is the Spansion S29GL256P. If the error, Kernel panic - not syncing: Attempted to kill init! But It does not do so, because I see the following kernel boot log: --------------------------------------------------------------------------------- [ 0.000000] Linux version 2.6.24 ([email protected]) (gcc version 4.0.2) #26 Fri Feb 15 10:06:09 EET 2008 Recall that using an initramfs just means supplying the kernel with an /init program for rootfs. $ cd $WORKDIR $ cat > hello.c << EOF > #include > #include

Try passing init= option to kernel. Among the various problems you might encounter, those related to your root filesystem are some of the most common ones I have seen and among those a very frequent problem is The next thing that I encountered was missing libs:
-sh: can't load library 'libgcc_s.
-sh: can't load library 'libc.so'
The files were indeed missing, not only in Now my /dev directory contains console file!! :-) Reply Name eMail (not visible) Subject (no text only in upper case; no HELP, URGENT...) TextHTML tags are not supported and links are

The kernel then expands and extracts a compressed cpio archive into it. http://webinweb.net/warning-unable/warning-unable-to-open-an-initial-console-initramfs.html Sign up for the SourceForge newsletter: I agree to receive quotes, newsletters and other information from sourceforge.net and its partners regarding IT services and products. Below are examples of inspecting the contents of a gzip'd cpio initramfs archive and restoring the image from its contents. pivot_root swaps the mount points for the root filesystem with some other mounted filesystem [go back] 2.

I will also have a try on my side and be back to you. replacing the kernel's default built-in skeleton cpio archive with a user-supplied initramfs. See for details. │ │ If RAM disk support (BLK_DEV_RAM) is also included, this │ also enables initial RAM disk (initrd) support and adds │ 15 Kbytes (more on some Check This Out Change to the /dev/ of your rootfs in the terminal and use mknod to create a console device file.

Running the following variant of the mkinitramfs(8) commandline keeps the temporary directory used to compile the initarmfs image in the present working directory: $ TMPDIR=$WORKDIR mkinitramfs -d initramfs-tools-nfs -o initrd.img-`uname -r`-nfs Thanks, Alister Re: [coLinux-users] Warning: unable to open an initial console. All works fine when I create rootfs with all device nodes already in /dev directory.

uImage places the root partition in RAM, while vmImage attempts to mount the root partition from Flash.

message from /init will not appear on the display. At least with Linux 3.11 [go back] 3. A simple intro to INITRAMFS is described below: │ CONFIG_BLK_DEV_INITRD: │ │ The initial RAM filesystem is a ramfs which is loaded by the │ boot loader (loadlin or lilo) and I am using nfs boot..

Various people suggested running this, which looked promising: mknod -m 600 dev/console c 5 1 mknod -m 666 dev/null c 1 3 mknod -m 666 dev/zero c 1 5 I have I am using buildroot-2011.05 and created a tarred rootfs from it. A detailed coverage of the subject is, therefore, beyond the scope of this tutorial. this contact form However, with the embedded configurations, inclusion of device file, /dev/console, was also necessary in order to provide a system console.

Does anyone know what I need to change?Any help would be appreciated.At the risk of deleting too much (I hope I haven't), I've trimmed down my boot logs to what seems Total pages: 16256 [ 0.000000] Kernel command line: mtdparts=physmap-flash.0:128k(boot),2M(kernel),-(rootfs) root=/dev/mtdblock2 rootfstype=jffs2 rw debug [ 0.000000] PID hash table entries: 256 (order: 8, 1024 bytes) [ 0.000000] console [ttySMX0] enabled [ 0.010000] On 10/31/12 10:53, Markos Chandras wrote: > From: Markos Chandras > > A /dev/console node must be present in rootfs when the Linux kernel > boots otherwise the kernel will print Like • Show 0 Likes0 Actions rsdio Nov 27, 2013 4:17 PMMark CorrectCorrect AnswerThanks Aaron.

Even that way I still get the same message. -----Original Message----- From: Henry Nestler [mailto:henry.ne@...] Sent: Tuesday, 7 July 2009 8:53 p.m. This scenario also serves as a trivial example of how an external initramfs can suppliment/extend an embedded initramfs.
