Hello all,
in our development enviroment we use some PowerMacs running Debian to compile U-Boot/Linux kernel. With the latest compilers I have some issues with u-boot: 1) gcc 3.3.4 - Linking of u-boot image failes: ... ld -Bstatic -T /opt/eldk-3.1.1/ppc_6xx/root/u-boot-1.1.3/board/eXalion/u-boot.lds -Ttext 0xFFF00000 -n $UNDEF_SYM cpu/mpc824x/start.o \ --start-group lib_generic/libgeneric.a board/eXalion/libeXalion.a cpu/mpc824x/libmpc824x.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/sk98lin/libsk98lin.a post/libpost.a post/cpu/libcpu.a common/libcommon.a --end-group -L /usr/lib/gcc-lib/powerpc-linux/3.3.4 -lgcc \ -Map u-boot.map -o u-boot make: *** [u-boot] Error 139
If I remove "-Map u-boot.map" from the Makefile the linking is successful.

2) gcc 3.3.6 - Linking OK(?), but image cannot run (cmd relocation failes):

Comments on that?
Regards, Torsten
P.S. When using the compiler from ELDK (3.3.3 )in native mode, the image compiles and runs OK.
