Dear Peter,

thank for reply :) I have found the problem. I using the custom kernel 2.6.13 but the kernel header is different from the standard kernel header.

my custom kernel which not using _NR_xxx . current solution is to manually point BR2 to custom kernel header which force uclibc to use __NR_socketcall. Now have another problem is to make BR2 to support custom kernel without kernel header.

include/asm-arm/unistd.h
===============================================================================
#if 0 /* reserve these for un-muxing socketcall */

#define __NR_socket                     (__NR_SYSCALL_BASE+281)
