thanks to all of u . maybe i should describe this in more detail. i have two arm9 boards,one hub ,one x86 notebook. i did some experiments in different status. 1. arm9 --------router ------- arm9 this failed. but 2. arm9 ----router ---- notebook this is sucessfull. i don't know the reason for it. maybe u can help me . and i noticed that bit_reverse() is uncompatible in arm board. so i use my_reverse() instead of bit_reverse(). static unsigned char transcode[]={ 0x00, 0x80, 0x40, 0xc0, 0x20, 0xa0, 0x60, 0xe0, 0x10, 0x90, 0x50, 0xd0, 0x30, 0xb0, 0x70, 0xf0, 0x08, 0x88, 0x48, 0xc8, 0x28,
