If ld can't find your functions, maybe you aren't including the object
file on the ld command line.

I have crt.o (the object file from crt.s) as a searate object in my
linker line:

LDSCRIPT  = lpc2106-FLASH.ld
LDFLAGS   =  -Map ${TARGET}.map -T${LDSCRIPT}
LOCATION  = /usr/local/arm
LD        = ${LOCATION}/bin/arm-elf-ld
OBJS      = main.o ata.o conio.o controller.o dir.o fat.o files.o \
            i2c.o interrupt.o ioports.o setup.o spi.o timer.o 

${TARGET}.elf : ${LDSCRIPT} crt.o ${OBJS}
	        ${LD} ${LDFLAGS} -o ${TARGET}.elf crt.o ${OBJS} ${LIBRARIES}

All of the OBJS are from C files, crt.o is the only object file
created from assembly language.

There is no problem with ld, almost everybody links an assembly
language startup file.
