[U-Boot-Users] U-boot for MIPS problems compiling...

Jerry;

I did a search through the u-boot mailing list archives as I was having 
problems compiling for my MIPS AU1550. Ironically, you seemed to be
having problems and made the exact fixes that I did in order to get as
far as you did in the compile process.

However, my progress has come to a standstil as has the thread bearing
your problem. I was hoping you could shed some light on the situation if
you've made any progress as of 2004-01-30 19:01

Cheers,

-=Chris

Could you give a more detailed description of your problems?

I had some problems finding working versions of gcc/binutils, but
finally succeeded with binutils 2.13 and gcc 3.2.3.

Either way, u-boot does not yet run on the Au1550 (except for here).
This depends on - among other things - differences in the dram
configuration registers (please complain privately to me daily about
this until i post the necessary patches to this list :)

Thanks so much for your quick reply. I was going to do some work on this
board as well independently in attempt to see if I can't get the machine to
boot from an ide HDD. I'll keep bugging you for the patches offline, 
but for the benefit of everyone else I'll elaborate a little more here:

Cross-compiling from x86 using: a custom built (crosstool) toolchain
gcc3.3.2-glibc2.3.2-binutils-2.15; I get this error:

I've seen other people compiling for the Au1x00 series have this similar
problem.

Not unsurprisingly while compiling natively with a similar toolchain: 
gcc-3.2.3,glibc-2.3.2,binutils-2.15 I get the same errors.

I know my toolchain is not BAD as I can perfectly build and execute the
resulting kernel; however, it may not be compatible with they way things
are done in u-boot. 

Perhaps Wolfgang or the people at DENX could put some input into their
toolchain version(s). I suppose I should just download it and check it out.
But I would really like to be in control of my own toolchain.

Cheers,

The current version (3.0) of the ELDK does not support  little-endian
MIPS  systems;  the  next  version  (3.1,  to  be released soon) will
support it. It's based on GCC-3.3.3,  glibc  2.3.1-51a  and  binutils
2.14.  I  have no problems compiling MIPS code with it (compile-clean
for all U-Boot boards, actyually  tested  for  MIPS  on  INCA-IP  and
XXS1500).

Best regards,

That's great. Hoping I'll be able to use your patches against what I
have so I can keep just one cross-compiler for kernel/u-boot building.

Leif: I've had some much better success switching to this toolchain:

gcc-3.2.3-glibc-2.2.3-binutils-2.13

However, now I'm getting the following error when building. I know it looks 
long and NASTY, but it basically amounts to an undefined reference. 
I was hoping you might know the solution.
 
Also, Yes, I know ld segfaults which is very bad and probably indicates a 
broken toolchain...sigh...I hope I don't get spanked for that! The undefined 
reference does come before the segfault though.

Dear Chris,

If ld segfaults, it _is_ brooken. Any segfaulting application is broken.

Now that you know that you are running  a  broken  tool,  you  should
forget about any other error messages it might report - they might be
completely bogus.

Fix your toolchain first.

Best regards,

Wolfgang Denk
