Hi,
I want to compile u-boot for board db64460 using MPC74448(PPC). Which
toolchain should i go for. From where i can download it.How to go about
compilation of u-boot with that toolchain.Ptease help....
Thanks

I never heard about this processor. Are you sure the name is correct?

Assuming  you  mean  MPC8448,  then  you  can  for  example  use  the
"ppc_74xx"  packacges of ELDK 4.0; all the remaining questions should
be answered by the manual (DULG).

I think It might be mpc7448 processor.

If it is mpc7448, the toolchain for ppc_74xx is OK!

Gotcha... I thought you were referring to gcc's terminology
of "stages". There, anything higher thant stage 1 is
compiled by itself which obviously won't work cross.

What you call stage1 is sometimes (and in Elinos, too) called
a "bootstrap gcc".

However: u-boot should be compilable with such a bootstrap
gcc, as it should not be dependent on glibc. (It is
bad enogh for it to be so dependent on several Linux
headers, but that is a compromise to be able to reuse
code from Linux - we had that before).

Marius.

What do you mean here - what else than stage 1 can a
cross compiler be?!

Marius.

Normally when you build a toolchain you first have to build a compiler
which is able to work without glibc headers (needs only to have C
support). Then you use it to build glibc and afterwards you recompile
your compiler with glibc support and whatever languages you need. 

At least that was the only way I could manage to build a working
toolchain. If you just build a toolchain with faked glibc headers you
will not be able to compile more than the kernel with it.

[U-Boot-Users] u-boot compilation

[André Stierenberg]

Hello,

i?ve problems compiling u-boot. I use cross compiler 2.95.3. When i 
compile u-boot i get an errer that he cant finde a file called 
"mach-types.h". What could it be? How can i fix this problems? I haven?t 
found the file in my filesystem.. not in the kernel directory (2.4.18 
and 2.5.0) and not in the directory of the cross compiler!

Andr?

mach-types.h should be in the include/asm-arm/ directory of your kernel
tree. Are you sure you have installed a correct toolchain and kernel
source?

No. No file "mach-types.h" is needed anywhere in  the  U-Boot  source
code.  If  the compiler thinks it needs it (and cannot find it), then
the cross compiler is misconfigured.

Get a working set of tools.

2.95.3. It seems like you are doing something substancially wrong - can
you tell us what you did?

My impression when I looked at this toolchain for the last time was that
it is only a stage 1 toolchain - at least this is what the build script
generates.

Could you cut-and-paste the error message plus some context? It's a
little bit difficult to find out what happens if you don't give us more
information.

Not sure what you've meant, but I'm using the 2.95.3 from www.arm.linux.org.uk 
to compile armboot, now with my u-boot tries. I used it with Linux up to 
2.4.17, now I'm using 3.2 (from the same location). It does NOT work with 
redboot.

One thing that one has to do with this 2.95.3 right is the installation 
location. It has to be /usr/local/arm/2.95.3 so that your PATH is 
/usr/local/arm/2.95.3/bin:$PATH
