[U-Boot-Users] Compiled system and target board mismatched while make U-boot image..

[Charles C.K.Lai]

Dear Thomas,

    I make my U-boot image from PC to DBAu1550,
    I used GCC 3.4.4, with mipsel-linux-sdelinux-6.03.01-1 toolchain,
    while I make my U-boot image with U-boot-1.1.4,
    I got the following messages:

    mipsel-linux-ld: hello_world.o: compiled for a little endian system and 
target is big endian
    mipsel-linux-ld: hello_world.o: endianness incompatible with that of the 
selected emulation
    mipsel-linux-ld: failed to merge target specific data of file 
hello_world.o

    I searched for related articles on U-Boot Website and Mailing lists,
    but I can't find out any helpful messages to fix the problem.
    Did I miss some patches? Do you have the reference material for this 
problem?
    Thanks a lot.

Hi.

Use dbau1550 for big endian version.

Use dbau1550_el for little endian version.

Your toolchain is little endian.

/Thomas

  No. I think problems are in linker script.

  I use sdelinux-5.03.06-1 (gcc-2.96) and gcc-3.3.4 from uClibc toolchain.
  both compiler needs to apply attached changes.

  Maybe your compiler can generate a file for little-endian code to big-endian
  binary format. but sdelinux or uClibc toolchain are not.

  Please report If your compiler does not have problems with this patch, 
  if it is noproblem, consider to marge this. > support at denx.de

What I change is:
 remove OUTPUT_FORMAT: It will use default format.
 remove -EL or -EB : It will use toolchain default.

This is not a dbau1550 question IMHO. It is an endian question for mips
platforms and I am not qualified to determine if it is correct or not.
I use big endian and ELDK ;-)

Yessir!! I'm here at work. What's up?

Ummm... What shall I say? ELDK for  MIPS  supports  both  LE  and  BE
configurations, and both work just fine, except for the fact that the
dbau1x00  port  produces  warnings  because it is broken as it uses a
definition of HZ which is not 1000:

Configuring for dbau1x00 board...

 130072    4548   22864  157484   2672c u-boot


IMHO it's clearly a toolchain problem, but who am I to know such things?

   Thank you for reply.

   ELDK user is ok. but with mipsel-linux-gcc, and to comile for
   little, there is a 2 problem.

1. always add -EB to compiler.

-- cpu/mips/config.mk ---
ifneq (,$(findstring 4KCle,$(CROSS_COMPILE)))
ENDIANNESS = -EL
else
ENDIANNESS = -EB
endif

   this means, to compile for little endian,
   part of cross compiler name have to has a name of "4KCle".
   otherwise, it will put -EB.

   I think, we do not need to put -EL or -EB, compiler default
   is enough.

2. examples/mips.lds?board/dbau1x00/u-boot.lds

   OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips",   "elf32-tradbigmips")

   this specify bigendian format.

mipsel-linux-ld -g  -Ttext 0x80200000 -T mips.lds \
        -o hello_world -e hello_world hello_world.o libstubs.a \
        -L/usr/src/mldbox/gcc-3.3.x/toolchain_mipsel/bin-ccache/../lib/gcc-lib/mipsel-linux-uclibc/3.3.4 -lgcc
mipsel-linux-ld: hello_world.o: compiled for a little endian system and target is big endian
mipsel-linux-ld: hello_world.o: endianness incompatible with that of the selected emulation
File in wrong format: failed to merge target specific data of file hello_world.omipsel-linux-ld: libstubs.a(stubs.o): compiled for a little endian system and target is big endian
mipsel-linux-ld: libstubs.a(stubs.o): endianness incompatible with that of the selected emulation
File in wrong format: failed to merge target specific data of file libstubs.a(stubs.o)

  To fix these error,
  I need to change 
  OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips",   "elf32-tradbigmips")
  to
  OUTPUT_FORMAT("elf32-tradlittlemips", "elf32-tradlittlemips", "elf32-tradlittlemips")

  or deleteing this line also work.
  so, if ELDK works, without this line, please delete it.

[U-Boot-Users] Re: Compiled system and target board mismatched while make U-boot image..

[Charles C.K.Lai]

Dear Thomas,

    My procedure is:

    make dbau1550_el_config
    make dep
    make all

    and I modified the following files to fit the toolchain:

    Makefile:
    ifeq ($(ARCH),mips)
    CROSS_COMPILE = mipsel-linux-

    cpu/mips/config.mk:
    v=$(shell \
    mipsel-linux-as --version|grep "GNU assembler"|awk '{print $$3}'|awk -F 
. '{print $$2}')

    ifneq (,$(findstring mipsel,$(CROSS_COMPILE)))

    Do I miss some files to meet the toolchain?
    Thanks a lot.

  I'm sorry, but I do not know about mipsel-linux-sdelinux-6.03.01-1.
  I use sdelinux-5.03.06-1(2.96-sdelinuxmips-040127).

  maybe, use -mcpu=r4400 or -mips32 insted.

Dear Hiroshi, 

    I modified the files with your patches, 
    and made my u-boot image again, 
    I got the following error message: 

    cpu/mips/start.o /home/charles/work/u-boot-1.1.4/cpu/mips/start.S
    cc1: error: invalid option `-mcpu=4kc'

    Does it mean the cpu selection was wrong?
