problem with initramfs

Altera_Forum · ‎07-11-2006

hello all friend

i have made kernel image with initramfs.i have used nios ide fot it.

for intramfs ,i have made rootfs sourse with help of nios (filesystem project).

but when i load it on board then i get folowing messeges..

Linux version 2.6.11-uc0 (Administrator@WINWORK_013) (gcc version 3.4.1 (Altera

Nios II 5.0 b73))# 2 Tue Jul 11 14:25:43 IST 2006

uClinux/Nios II

Built 1 zonelists

Kernel command line: root=/dev/mtdblock0 ro

Mount-cache hash table entries: 512 (order: 0, 4096 bytes)

Kernel panic - not syncing: junk in compressed archive

i know i have to select linux system for building vmlinux not nios ide on window.

but can you help me to build kernel with initramfs on nios ide.

Jdhar and I had tried a lot on cygwin, but failed. You may track the old posts. Your problem may be in kernel Makefile, there are too many dos2unix.

I don't recommend work on IDE. Actually I think it is totally wrong. But it is all up to you. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

thaks hippo for reply.

now i am starting with linux redhat-9.

i have downloaded nios2linux-1.4.zip and build0411.zip.

but i can't understand your 3and 4 step in buildrootguide.

which folder i have to make in ~/download folder. and which source i have to put in which folder.

please guide me hippo....

Altera_Forum · ‎07-12-2006

soory hippo

i get idea how to start.

but i have some query.

1> i have linux redhat -9.is it posible on radhat -9?

2> can i use source uClinux-dist-20060511.tar.bz2 in place of uClinux-dist-

20051110.tar.bz2.

please reply as soon as posible.

the make command in redhat 9.0 may be too old.

you'd better use Fedora core 5.

Don't follow the buildroot guide !!

The wiki is easier now. follow step 1-3.

hi hippo

i have read step1-3 .i have some query.

according it and my understanding for it,i have made following doc for my reference .before going to work on linux, i want to be sure am i right or wrong .

can you tell me where i am wong in my doc.

i am following below step:

-> i have copy source code into home folder

ls

=> o/p:

uClinux-dist-test-20060511.tar.bz2 uClinux-dist.diff.gz nios2gcc.tar.bz2

nios2libs.tar.bz2 build0411.zip nios2rootfs.tar.bz2 nios2linux-1.4.zip

-> Login as a user account on Linux PC, open a terminal.

pwd ->/home

su -# root passwd

tar jxf nios2gcc.tar.bz2 -C /

exit

->so now /opt is in home folder.next command for setting path

->for /home/opt/nios2/bin

PATH=$PATH:/home/opt/nios2/bin:$usr/bin

->for checking command

nios2-linux-uclibc-gcc -v

->Login as a user account on Linux PC, open a terminal.

su -# your root passwd

tar jxf nios2libs.tar.bz2 -C /

exit

-> i have query after above step => have i to give PATH for nios2libs ? if

-> yes, then where? .

?

-># login as a user account, don't use root account,

cd /home

tar jxf uClinux-dist-test-20060511.tar.bz2

cd uClinux-dist-test

zcat ../uClinux-dist.diff.gz | patch -p0

-> still in /home/uClinux-dist-test dir, don't cd linux-2.6.x

make menuconfig

make linux_hwselect SYSPTF=your_system.ptf

make romfs# to create romfs dir, make will fail, ignored

make menuconfig

-> compile kernel and apps

make

-> rebuild kernel for initramfs

make linux image

->for checking command

nios2-linux-uclibc-gcc -v

->Login as a user account on Linux PC, open a terminal.

su -# your root passwd

tar jxf nios2libs.tar.bz2 -C /

exit

-># login as a user account

cd /home/slsnios/

cd uClinux-dist-test

zcat ../uClinux-dist.diff.gz | patch -p0

-> still in /home/slsnios/uClinux-dist-test dir, don't cd linux-2.6.x

make menuconfig

make linux_hwselect SYSPTF=your_system.ptf

make romfs# to create romfs dir, make will fail, ignored

make menuconfig

But when i gave make command ,then i got following messages

slsnios,

to pick up the original thread,

I had the same problem using the IDE, the archive it produces on Cygwin seems to be corrupted. I use the IDE for Kernel developement, but I have also a Linux machine for compiling applications or libraries.

To bypass the problem of the corrupted archive I create the archive on Linux machine FC4 and include it in the IDE.

In the file linux-2.6.x\usr\initramfs_data.s you must specify the path where your archive resides. In the kernels menuconfig I picked the same path.

On the Linux machine you create the initramfs_data.gpio.gz archive and copy it to the directory from where it should be included.

Whenever you build the kernel in the IDE your archive gets picked instead of the IDEs archive.

Altera_Forum · ‎10-02-2006

However,

this method also fails if the archive is bigger than 100k.

Then a compiler warning like: file truncated

shows up.

So in my opinion initramfs only works under Linux
