Hello, all.
I'm a newbie Korean linuxer - specifically to arm linux.
Since I'm working on the embedded linux project for ARM, I have to build cross
toolchains.
After lots of trouble I've built it successfully with many advices from
http://inkvine.fluff.org/~chris/arm-tools.html
Yes. I could build the Linux kernel 2.2.14 with patch-rmk4 successfully.
But the vmlinux image was elf-32littlearm format and the evaluation board engineer
said that I have to build a big-endian image.
So I've fiddled out Makefiles and Rules.make to add -mbig-endian switch to gcc and
-EB switch to ld.
And finally got error about arch/arm/lib/extractconstants.pl with objdump output of
big-endian compiled objects.
I've been reaching big-endian kernel image ( Yes, It's the goal ) ...
But I had a doubt that "Is this kind of things right? If I have a toolchain configured
to support big-endian default?"
So I returned to web-life, finding any information... then I've got information from
the web page mentioned at the beginning.
It's the target name.
In "Picking a target name" section from the web page...
Not only arm, but armv4l and armv4b are also target names.
I've tried it on binutils-2.9.5.0.29 first, but got errors like this.
-----------------------------------------------------------
[root@fraser binutils-2.9.5.0.29]# pwd
/home/cross-compiler/object_dir/binutils-2.9.5.0.29
[root@fraser binutils-2.9.5.0.29]# /home/cross-compiler/source_dir/binutils-2.9
.5.0.29/configure --target=armv4b-linux --prefix=/usr/cross-compiler/tool_dir/h
ost/sparc-sun-solaris-for-arm/
Configuring for a sparc-sun-solaris2.6 host.
Invalid configuration `armv4b-linux': machine `armv4b' not recognized
Unrecognized target system name armv4b-linux.
------------------------------------------------------------
What's the point of problem? Are there any patches to support armv4b? Is the word
"armv4b" badly located?
Please answer.
Thanks in advance.
Have a nice day.
