build uclinux error

THANKS

I WANT TO DO ACCORDING TO hippo,I downloads the Nios II Linux Distribution v1.4 ,and build.zip.BECAUSE THE NET DOWLOAD IS SLOW,SO I DOWNLOAD THIS FILES:uClinux-dist-20051110.tar.bz2,busybox-20060320.tar.bz2,uClibc-20060320.tar.bz2 AND buildroot-20060320.tar.bz2

,then I place this files in ~/download instead of WGET commond.

COULD YOU HELP HOW TO MODIFY THE BUID FILE:

You will need wget more files for buildroot, and take more time.

Please download the binary tools and rootfs from the nios wiki, and install them.

Then use this script to prepare the sources, and you can compile the kernel.

But I still recommand you follow the uClinux-dist approach as in the wiki.

#!/bin/bash
rm -rf ~/buildroot ~/rootfs ~/linux-2.6.x ~/download/mx140 ~/uClinux-dist ~/apps#  to prepare kernel source
cd ~/download
mkdir mx140
cd mx140#  convert the crlf with unzip -a
echo "prepare kernel source"
unzip -aoq ../nios2linux-1.4.zip#  kernel 2.6.11-uc0 source ported by microtronix
cp -a plugins/com.microtronix.nios2linux.kernel_1.4.0/linux-2.6.x ~
cd ~/linux-2.6.x
patch -p0 <~/download/kernel.diff
cp ~/download/kernel.config ~/linux-2.6.x/.config#  apps ported by microtronix, only Makefile of inetd, ftpd and boa are patched to use the toolchains
mkdir ~/apps
cp -a ~/download/mx140/examples/software/linux/apps/* ~/apps
cd ~/apps
patch -p1 <~/download/mx140apps.diff#  to prepare uClinux-dist source
cd ~/download
echo "prepare uClinux-dist source"
cd ~
tar jxf ~/download/uClinux-dist-20051110.tar.bz2
cd ~/uClinux-dist
patch -p0 <~/download/uClinux-dist.diff
touch ~/uClinux-dist/vendors/Altera/nios2nommu/inittab

thanks hippo,because i want to port uclinux to my own board,so i want to according to you, i think the WGET in the build script is to download four file ,so i download the four file instead of downloading the four file because the net is slow , do you think so? if so , i want you modify the script ,
by the way, I found that no altera directory in the uClinux-dist\vendors\,why?

thanks!!!!

The buildroot process will wget a lot more files. So I don't suggest you run buildroot.

(My best suggestion for you)
Follow the binary toolchain and uClinux-dist as in nios wiki.
You need to download only three files with your browser,
http://nioswiki.jot.com/wikihome/operating...ios2gcc.tar.bz2 (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/binarytoolchain/nios2gcc.tar.bz2)
http://nioswiki.jot.com/wikihome/operating...ux-dist.diff.gz (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist/uclinux-dist.diff.gz)
http://www.uclinux.org/pub/uclinux/dist/uc...0060511.tar.bz2 (http://www.uclinux.org/pub/uclinux/dist/uclinux-dist-test-20060511.tar.bz2)

I know the network speed is slow. Please be patient and read some uClinux / Linux doc. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

OK.
step1. Do you have altera nios dev board?
If you have one, try out the prebuild zImage, as in the wiki http://nioswiki.jot.com/wikihome/operating...s/tryoutuclinux (http://nioswiki.jot.com/wikihome/operatingsystems/tryoutuclinux)

Step2, , download the binary tool http://nioswiki.jot.com/wikihome/operating...ios2gcc.tar.bz2 (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/binarytoolchain/nios2gcc.tar.bz2)
and install as in http://nioswiki.jot.com/wikihome/operating...binarytoolchain (http://nioswiki.jot.com/wikihome/operatingsystems/binarytoolchain)

step3, dowload
http://www.uclinux.org/pub/uclinux/dist/uc...0060511.tar.bz2 (http://www.uclinux.org/pub/uclinux/dist/uclinux-dist-test-20060511.tar.bz2) (take a long time)
and
http://nioswiki.jot.com/wikihome/operating...ux-dist.diff.gz (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist/uclinux-dist.diff.gz)

Then follow
http://nioswiki.jot.com/wikihome/operating...nux/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist)

That's OK.
First, you should read "before you start" in the wiki http://nioswiki.jot.com/wikihome/operating...ms/%c2%b5clinux (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux)
And build your nios2 hardware in sopc builder, compile to sof.

The install the binary toolchain (step2) and uClinux-dist (step3).
Now you can createt the kernel zImage,

and follow the "try out" to run it (step1),

then emerging the following information in the termiinal:

You need ncurses lib.
If you use Fedora core, "su -" to root and run "yum install ncurses ncurses-devel" .
