TQ2440网卡无法与PC连接，也无法与路由连接，是否DM9000网卡芯片坏了？

    几年前买的TQ2440开发板，因为种种原因，最近才重新捡起开始研究，但开发板用交叉线与PC连接不通，直接接路由也连接不通，烧入原来显示正常的镜像，启动信息如下：

请教，是否网卡芯片损坏？

看启动信息应该是网卡出现了问题，你重新格式下nand，重新烧下，如果还是不行就寄回来维修

测试了好几回，还是不行。如果是芯片问题的话，寄来寄去也挺麻烦的，我可以买网卡芯片，自行更换，谢谢版主。

查看网卡芯片，部分芯片引脚明显颜色发暗，怀疑芯片虚焊，后自己试着加焊，结果焊工差，芯片有7、8个引脚都歪了，还有2个焊盘脱落。还好弟弟是搞电脑维修的，只好求助他，把芯片热风枪吹下来，弄正引脚，掉落的焊盘，用细铜线引出来，全部搞定后，开机测试，一切正常。可能是开发板放置时间过长，加上电路板质量不太高，导致虚焊。经过一顿折腾，好在最后问题还是顺利解决了。
