EZBoard에 RTLinux 3.0 포팅한 자료입니다.
첨부된 diff-2.4.16-rmk2-ez1-rtl30는 리눅스 커널에
StrongARM 패치와 EZBoard패치와 RTLinux 패치를 가한것입니다.
(1) 방법이 제일 간단할 겁니다.
Xscale 보드에 설치하려면 (2) 방법을 따라하면 될 것같은데 저도 해보지는
않았구요. rtpatch-linux-2.4.16.rmk1를 분석해보면 의외로
커널에서의 수정부분이 적다는 걸 알수 있습니다.
그러니까 커널 보면서 손으로 수정해도 된다는 것이지요.
그럼.. Xscale에 성공하시면 올려주세요.
위 자료는 박재호님의 "임베디드 리눅스" IT Expert 라는 책에 보면 자세히
나와 있습니다.
(1) Most simple Installation
tar xvzf linux-2.4.16.tar.gz
cd linux
patch -p1 < ../diff-2.4.16-rmk2-ez1-rtl30
make ezboard_config
make menuconfig
# set the RTLinux support
make dep
make zImage
cp arch/arm/boot/zImage /tftpboot
(2) General procedure
tar xvpfz linux-2.4.16.tar.gz
cd linux
cat ../patch-2.4.16-rmk2.gz | gunzip | patch -p1
cat ../diff-2.4.18-rmk7-ez1 | patch -p1
# change the hunk fail manually
cat ../rtpatch-linux-2.4.16.rmk1 | patch -p1
cd ../
mv linux linux-2.4.16-rmk2-ez1-rtl
cd linux-2.4.16-rmk2-ez1-rtl
mv -f Makefile Makefile.org
sed "s/ARCH := .*$/ARCH := arm/1" Makefile.org > Makefile
mv -f Makefile Makefile.org
sed "s/CROSS_COMPILE .*=$/CROSS_COMPILE = arm-linux-/1" Makefile.org >
Makefile
rm -f Makefile.org
export PATH=`echo $PATH`:/usr/local/arm-dev/bin
make ezboard_config
make menuconfig
# be sure to select CONFIG_RTLINUX options
make dep
make zImage
cp arch/arm/boot/zImage /tftpboot
(3) RTLinux Installation
tar xvpfz rtlinux-3.0.tar.gz
cd rtlinux-3.0
cat ../patch-rtlinux-3.0-arm | patch -p1diff-2.4.16-rmk2-ez1-rtl30
cat ../patch-rtlinux-3.0-arm-jhp1 | patch -p1
ln -s /ez/cch/rtlinux/linux linux
cd ..
mv rtlinux-3.0 rtlinux-3.0-arm-jhp1
cd rtlinux-3.0-arm-jhp1
export PATH=`echo $PATH`:/usr/local/arm-dev/bin
make oldconfig
make dep
make CROSS_GCC_ROOT=/home/embedded/arm/gcc-2.95.3-arm

Troubleshooting the Error Message
(1)
fifo_module.c: In function `init_module':
fifo_module.c:92: `GFP_BUFFER' undeclared (first use in this function)
fifo_module.c:92: (Each undeclared identifier is reported only once
fifo_module.c:92: for each function it appears in.)
make[1]: *** [fifo_module.o] ¿?·? 1
make[1]: ³ª°¨ `/ez/cch/rtlinux/rtlinux-3.0/regression' ?ð·º??¸?
make: *** [modules] ¿?·? 2
Solution :
If an error occurrend when compiling like
"undeclared GFP_BUFFER...", add the following line in
the file that have GFP_BUFFER.
This message is caused by the kernel version, a new group message says
the GFP_BUFFER is no longer used as is updated as GFP_NOFS.
#define GFP_BUFFER GFP_NOFS
(2) When writing to flash memory, all of the
external devices that consumes 3.3V source from ezboard should be
turn off.

okay, did you ever manage to compile an arm gcc? i read that there is a
configure option like "--no-shared-libgcc", which will supposedly
create a
wholly static libgcc, which is what we want. apparently the
_GLOBAL_OFFSET_TABLE_ is in there because it is not a static library.
why
it's not a .so is beyond me (but not in that "it's stupid" sense of
beyond
me, but really that "i don't understand" sense).
aaanyhow, if you manage to make a static libgcc, this command should
come
up empty:
nm $(arm-linux-gcc -print-libgcc-file-name) |
grep "_GLOBAL_OFFSET_TABLE_"
if you manage that, you can then try to recompile rtl_sched.o (in
rtlinux-3.0-arm/schedulers, run "make rtl_sched.o", or maybe just
compile
the whole thing if it complains, but perhaps skip the laborious install
process and just copy the resulting schedulers/rtl_sched.o).
alternatively i can try and build a static libgcc, but i figure you were
in the best position since you had already done most of it.
note that libgcc isn't libc, i think it's at a lower level than libc,
and
is provided by gcc itself. but, i could be wrong.
