Regarding the linker script what exaclty should i look for, more
details would be helful.
Anyway i have added the LD command from the compilation windows.
|----------------------------------------------------------------------------------------------------------------------|
ld -Bstatic -T /home/rashetty/u-boot-1.0.0/board/sc520_cdp/u-boot.lds
-Ttext 0x387c0000 $UNDEF_SYM cpu/i386/start.o cpu/i386/start16.o
cpu/i386/reset.o \
--start-group board/sc520_cdp/libsc520_cdp.a cpu/i386/libi386.a
lib_i386/libi386.a fs/jffs2/libjffs2.a fs/fdos/libfdos.a
fs/fat/libfat.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 lib_generic/libgeneric.a -L
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2 -lgcc --end-group \
-Map u-boot.map -o u-boot
|----------------------------------------------------------------------------------------------------------------------|
I am doing this for first time. More detailed information would be
more helpful for newbie like me.
