项目是软硬分开的，我现在调试，软件组说我印制板布线有

可是我想找找真正的原因啊，功能上基本上都正常，只不过偶尔会出现这样的BUG，就死机了，真的是硬件问题吗？？

你们公司软件组太强悍了

布线有问题都知道.....<br /><br />你降频运行试试.<br /><br />不过:<br />PC&nbsp;is&nbsp;at&nbsp;Tx_UpdateTxCounters+0x100/0x110<br />LR&nbsp;is&nbsp;at&nbsp;Smsc911x_get_stats+0x54/0x5c<br />pc&nbsp;:&nbsp;[&ltc015434c&gt]&nbsp;&nbsp;&nbsp;&nbsp;lr&nbsp;:&nbsp;[&ltc0154674&gt]&nbsp;&nbsp;&nbsp;&nbsp;Not&nbsp;tainted<br />&nbsp;ip&nbsp;:&nbsp;00000002&nbsp;<br /><br />注意一下这个函数.
