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.
