Update to buildroot toolchain for nios2

Alex,

ftp://linuxforum.net/ftp.gcc.gnu.org/rele...c-3.4.3.tar.bz2 (ftp://linuxforum.net/ftp.gcc.gnu.org/releases/gcc-3.4.3/gcc-3.4.3.tar.bz2)

The buildroot.config uses bintuils-0.15,gcc-3.4.3,kernel header 2.6.11, uClibc snapshot, busybox snapshot.

tar jxf buildroot-snapshot.tar.bz2
mkdir buildroot/dl

in buildroot dir,

make menuconfig, and just save and exit.

unzip the configs.zip into buildroot/dl, copy buildroot.config to buildroot/.config.

then in buildroot dir, make.

it will build the compiler,uclibc,busybox and rootfs.nios2.ext2.

the only problem remained, is the elf2flt.

use the old one as in post#24,

add the line

LDFLAGS+=-Wl,-elf2flt="-s 16000" -Wl,-v -Wl,-d

to buildroot/build-nios2/busybox/Rules.mak

remove file buildroot/build-nios2/busybox/busybox

and in buildroot dir, make again.

The rootfs is built into a ext2 image.

Login as root account. Mount it and copy to your rootfs,

mkdir /mnt/v1
mount -o loop buildroot/rootfs.nios2.ext2 /mnt/v1
cp -a /mnt/v1/*  your_rootfs_dir
chown -R your_username:your_username your_rootfs_dir
umount /mnt/v1
