Lpc2000

Hi group,
i`m doing my first steps with LPC2114 and gnuarm. I�ve found a trouble 
when i try to link the objects files from c-sources and as-sources with 
arm-elf-ld and the following parameters : -Map main.map -TPruebaLPC.ld -
t. The linker tell me: Undefined reference to `THOSE FUNCTIONS THAT ARE 
WROTE IN ASSEMBLER`; although i�ve declared those functions in my 
headers files and properly included. Hope someone can help me. Thanks.
