今天第一次调试mot的xpc8245（以前从没有作接触过）,bsp原来支持的是带威盛的686B南桥芯片的板子,但我们的板子是新作的,没有用南桥,外面直接挂了一个intel的82559,内存条,bootrom芯片,两个串口,4个PCI插槽. 忙了一天也没有能把串口驱动起来.苦死了!现在还在公司加班....:( 唉,我得回家了.明天继续吧.对了,如果谁有powerPC汇编指令集的详解或者作过8245、603，请帮我一把呀！呵呵。

当然是找人焊啦。我最烦调BGA封装的片子了。这不忙了半天一点进展都没有。：（ 这个破8245又没有GIO口，没法点灯，想在romInit.s中直接插入汇编指令来打通串口，但它愣是不出来！还有哇，8245对rom的数据线居然是颠倒了的，d0-d7应该接d7-d0。烦透了！[em25]
