[U-Boot-Users] trouble to build u-boot.bin with objcopy

[valerian NA]

Hi all,

I work with a linux cross-compiler (codesourcery with gcc 4.2.3) for
embedded powerpc targets (mpc8248).
So I tried to compile u-boot (version 1.1.6). It works fine with another and
older version of gcc (3.3.2) but with the new cross-compiler (4.2.3) I have
trouble to do this part :
powerpc-linux-gnu-objcopy --gap-fill 0xff -O binary u-boot u-boot.bin

This command freezes and uses a lot of memory without sucess (maybe I have
not enough disk space).

I decided to launch without "--gap-fill" to see the reaction :
powerpc-linux-gnu-objcopy -O binary u-boot u-boot.bin
It creates u-boot.bin file, and the system (host ls -al) tells that this
file has a size nearest to 4GiB

So I think it's a problem in the mapping of u-boot :
powerpc-linux-gnu-objdump -h u-boot

u-boot:     file format elf32-powerpc

Just a command to show you how objs are compiled :
powerpc-linux-gnu-gcc -g  -Os   -fPIC -ffixed-r14 -meabi -D__KERNEL__
-DTEXT_BASE=0xFC000000  -I/a/good/path/to/include2 -I/a/good/path/to/include
-I/a/good/path/to/include -fno-builtin -ffreestanding -nostdinc
-isystem/usr/freescale-gcc-4.2.3/bin/../lib/gcc/powerpc-linux-gnu/4.2.3/include
-pipe  -DCONFIG_PPC -D__powerpc__ -DCONFIG_8260 -DCONFIG_CPM2 -ffixed-r2
-ffixed-r29 -mstring -mcpu=603e -mmultiple -Wall -Wstrict-prototypes -c -o
/a/good/path/to/common/cmd_mac.o cmd_mac.c

And another command to see how u-boot is built :
powerpc-linux-gnu-ld -Bstatic -T /a/good/path/to/a/u-boot.lds -Ttext
0xFC000000  -n $UNDEF_SYM cpu/mpc8260/start.o \
                        --start-group lib_generic/libgeneric.a
board/rmp100/librmp100.a cpu/mpc8260/libmpc8260.a lib_ppc/libppc.a
fs/cramfs/libcramfs.a fs/fat/libfat.a fs/fdos/libfdos.a fs/jffs2/libjffs2.a
fs/reiserfs/libreiserfs.a fs/ext2/libext2fs.a net/libnet.a disk/libdisk.a
rtc/librtc.a dtt/libdtt.a drivers/libdrivers.a drivers/nand/libnand.a
drivers/nand_legacy/libnand_legacy.a drivers/sk98lin/libsk98lin.a
post/libpost.a post/cpu/libcpu.a common/libcommon.a --end-group -L
/usr/freescale-gcc-4.2.3/bin/../lib/gcc/powerpc-linux-gnu/4.2.3 -lgcc \
                        -Map u-boot.map -o u-boot

If I do it with .a files compiled with gcc3 and after I do objcopy it works
but if I do it with .a files compiled with gcc4 it freezes.

NB :
- with gcc3, u-boot.bin has a size of 121KiB
- UNDEF_SYM=
-u__u_boot_cmd_autoscr -u__u_boot_cmd_bootm -u__u_boot_cmd_diskboot
-u__u_boot_cmd_end -u__u_boot_cmd_go -u__u_boot_cmd_help -u__u_boot_cmd_ide
-u__u_boot_cmd_printenv -u__u_boot_cmd_question_mark -u__u_boot_cmd_reset
-u__u_boot_cmd_setenv -u__u_boot_cmd_start -u__u_boot_cmd_version
- I know u-boot 1.1.6 is an older version but I have to use it not another

Thanks a lot for your attention and your futurs ideas...

Val.
