应该不是网线的问题，同样的线接电脑上是没问题的。有谁遇到过这个问题吗？是怎么解决的呀

unsigned int oldval_bwscon = *(volatileunsigned int *)S3C2410_BWSCON;

unsigned int oldval_bankcon4 = *(volatileunsigned int *)S3C2410_BANKCON4;

*((volatile unsigned int *)S3C2410_BWSCON) =

(oldval_bwscon & ~(3<<16)) |S3C2410_BWSCON_DW4_16 |

S3C2410_BWSCON_WS4 | S3C2410_BWSCON_ST4;

*((volatile unsigned int *)S3C2410_BANKCON4) =0x1f7c;

这些没有改，不知道这些代码的作用呀

改过以后就可以了
