thanks for your help. i think i am close to running uclinux on my development board successfully. i am no longer having any trouble, which i am aware of doing the buildroot. however, when i try to run uclinux on my development board i see this output.

uncompressing linux... ok, booting the kernel.

linux version 2.6.16 (user@localhost.localdomain) (gcc version 3.4.6)# 1 preempt fri apr 28 13:43:33 est 2006

<continues like i would expect until>

init started: busybox v1.2.0-pre0 (2006.04.28-07:53+0000) multi-call binary

<nothing else is printed out to the jtag>

any thoughts on what may be wrong? is my problem probably with busybox or is it something wrong with my kernel?

i just went back and tried to redo "make" for my buildroot, and i recieved this error.

# these are in /lib, so...

rm -rf /home/user/buildroot/build_nios2/root/usr/lib/libgcc_s*.so*

cp -a /home/user/buildroot/build_nios2/staging_dir/nios2-linux-uclibc/lib/libgcc_s* /home/user/buildroot/build_nios2/root/lib/

cp: cannot stat `/home/user/buildroot/build_nios2/staging_dir/nios2-linux-uclibc/lib/libgcc_s*&#39;: no such file or directory

make: [/home/user/buildroot/build_nios2/root/lib/libgcc_s.so.1] error 1 (ignored)

touch -c /home/user/buildroot/build_nios2/root/lib/libgcc_s.so.1

touch -c /home/user/buildroot/build_nios2/root/usr/bin/ldd

i check and /home/user/buildroot/build_nios2/root/lib is an empty folder. from the error message, i would expect that there is suppose to be atleast one file in this folder.

The error in building *.so should be ignored, because there isn&#39;t so (shared object) support in nios2 uClinux.

The busybox is doing init .

Please try the minimal inittab, rebuild busybox and zImage.

make -C ~/buildroot/build_nios2/busybox clean

make -C ~/buildroot# prepare root fs

rm -rf ~/rootfs

mkdir ~/rootfs

cp -a ~/buildroot/build_nios2/root/* ~/rootfs

cd ~/rootfs# remove include and lib to save space# the dev nodes are generated via ~/download/rootfs_list

rm -rf dev usr/include usr/lib# you may use this instead of the one from buildroot

cp ~/download/inittab etc

rm ~/linux-2.6.x/usr/initramfs_list

make ..... zImage
