标题: *******2.6.8内核运行不了*****求助


    新手，第一次发帖求教，如有说的不明白的地方，欢迎指出，一定改正。
    现有优龙公司FS2410开发板和核心板一块，核心板是在自己新做的底板上用的。开发板光盘上带BOIS、2.4.18版本内核及根文件系统；核心板光盘带BOIS、2.6.8版本内核及根文件系统。

    这两套内核和根文件系统在2410开发板上都能成功运行，但是在核心板上烧写时都是到一半就终止，没有报错。自己做的底板上只焊接了电源部分、232串口、USB及网口部分。

    下图是2.6.8内核运行串口信息，是到网口驱动部分停止的。

    请教各位前辈，这是硬件问题影响到内核吗？（因为在2410开发板上都能正常运行），还是内核的问题？（因为底板上只焊接了烧写内核和根文件系统所需的串口、USB，网口是在运行到网口驱动停止后才焊接的）
    从硬件查找或者内核上都觉得没有明显问题，现在不知道该从哪入手，欢迎大家指点方向！
