Regarding the second question.
I believe David & Greg replied on this in a similar email thread 3 weeks
ago. I intended to give my 2 cents since I had some experience on this, but
I reply on this instead.
I currently do compile both kernel and user-level applications using
CodeSourcery's latest for ColdFire, i.e. 4.2-47. It seems to work fine,
however there are a couple of things that you have to do to the 20070131
distro and the toolchain itself.
1) For you vendor, edit vendor/<whatever>/<board>/config.arch and change to
this
CROSS_COMPILE=m68k-uclinux-
2) For your vendor, edit vendor/<whatever>/<board>/Makefile and change all
explicit references to m68k-elf-<objcopy, gcc etc> to m68k-uclinux-<objcopy,
gcc etc>
3) Edit uClibc/libc/sysdeps/linux/m68k/clone.S, and remove the line that
says
.set clone,__clone
See the following patch
*** 80,85 ****
.weak clone
clone = __clone
#else
- .set clone,__clone
#endif
--- 80,84 ----
4) Uncompress the latest CS toolchain and do
$ cd freescale-coldfire-4.2/lib/gcc/m68k-uclinux/4.2.1/include
$ ln -s ../include-fixed/limits.h limits.h
5) Obviously, append the freescale-coldfire-4.2/bin to your PATH variable
That's it! Now it compiles fine. Let me know how it goes.
Greg & David. You might want to consider the clone.S change above. And
possibly the makefile changes

Harry
