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

Hi.
Use dbau1550 for big endian version.
Use dbau1550_el for little endian version.
Your toolchain is little endian.
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@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 ;-)
Wolfgang?

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:

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.

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.

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.
