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:

eg, i am user hippo,

-> login as a user account, eg hippo on linux pc, open a terminal.

-> i have copy source code into /home/hippo folder

ls /home/hippo

=> o/p:

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

su -# root passwd

tar jxf /home/hippo/nios2gcc.tar.bz2 -c /

exit

->so /opt/nios2/bin has the cross gcc. next command for setting path

->add /opt/nios2/bin to path ( if you save it to .bash_profile, logout and login again)

path=$path:/opt/nios2/bin

->for checking command

nios2-linux-uclibc-gcc -v

--> install uclinux-dist source

cd /home/hippo

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

cd uclinux-dist-test

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

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

make menuconfig

make linux_hwselect sysptf=path of 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

--> the kernel in elf object format will be /home/hippo/uclinux-dist-test/images/zimage
