[U-Boot-Users] Want to Use char array without System support, but cannot find memset function.

Hi, all:

I am trying write a little bootloader same like the uboot. In my program I need to use the char array. when I link my program the ld show me an error: undefined reference to 'memset'. I want to know which lib includes this symbol. I use the arm-linux-gcc 3.2 I try to use the lib file libc.a (/usr/local/arm/lib) then the system show me another error: "Not enough room for program headers (allocated 5, need 6)"

Can somebody help me? Thanks.
