Subject: [openrisc] linux 2.6.19 problem with or1ksim according to embecosm
or1k_setup.pdf
I'm using Ubuntu 8.04 i386 version, gcc 4.2.3
1. The segment fault problem has been avoided, by using "tcp:XXXX"
instead of "xterm:" in sim.cfg
2. The linux compile problem is still there, I've made a few shell
scripts to re-produce the linux compile problem.
The script:
# download:
# step 1: binutils
wget -c kernel_compile.log.bin
-O rgd_initrd-fb-03.ext2.bz2
# build
# step 0: clear /opt/or32
rm -rf /opt/or32/*
export PATH=$PATH:/opt/or32/bin
# step 1: binutils
echo Building binutils-2.16.1
tar xjf binutils-2.16.1.tar.bz2
cd binutils-2.16.1
bzcat -dc ../binutils_2.16.1_unified.diff_rgd_fixed.bz2 | patch -p1
cd ..
mkdir build_binutils
cd build_binutils
../binutils-2.16.1/configure --target=or32-uclinux --prefix=/opt/or32
make all
make check
make install
cd ..
# step 2: gcc basic
echo Building gcc-3.4.4 the first pass
tar xjf gcc-3.4.4.tar.bz2
cd gcc-3.4.4
bzcat -dc ../gcc-3.4.4-or32-unified.diff.bz2 | patch -p1
cd ..
mkdir build_gcc
cd build_gcc
../gcc-3.4.4/configure --target=or32-uclinux --prefix=/opt/or32
--enable-languages=c
make all
make install
cd ..
# step 3: gdb 6.8
echo Building gdb-6.8
tar xjf gdb-6.8.tar.bz2
cd gdb-6.8
bzcat -dc ../embecosm-or32-gdb-6.8-unified-patch.bz2 | patch -p1
cd ..
mkdir build_gdb
cd build_gdb
../gdb-6.8/configure --target=or32-uclinux --prefix=/opt/or32
make all
make install
cd ..
# step 4: linux 2.6.19
echo Configuring linux-2.6.19
tar xjf linux-2.6.19.tar.bz2
cd linux-2.6.19
bzcat -dc ../linux_2.6.19_or32_unified_simtested.bz2 | patch -p1
bzcat -dc ../embecosm-or32-linux-2.6.19-general-patch.bz2 | patch -p1
cp ../rgd_initrd-fb-03.ext2.bz2 arch/or32/support/initrd-fb-03.ext2.bz2
bunzip2 arch/or32/support/initrd-fb-03.ext2.bz2
# in menuconfig, deselect OpenRISC Ethernet support
make ARCH=or32 CROSS_COMPILE=or32-uclinux- defconfig
make ARCH=or32 CROSS_COMPILE=or32-uclinux- menuconfig
echo Building linux-2.6.19
make ARCH=or32 CROSS_COMPILE=or32-uclinux- vmlinux
