新问题winbon 745 内核失败 Internal error: unknown data我们公司自己用winbon745开发了自己的板。bootloader能正确起来，就引导。
使用说明了书上所写的fx 7 linux.zip 0x7f020000 0x8000 –acxz
自己做的板写入内核成功后不能起动linux系统。

使用相同的内核文件写入winbon745所带的开发板，linux系统能起动，并在Kernel panic: VFS: Unable to mount root fs on 1f:00停止了。因为我目前只写入操作系统。
使用winbon745所带的开发板写入文件系统，系统就能正常跑起来。使用我们自己的板，问题一样。
在此向各位请教？谢谢
这个问题已经解决。原因是板的线路问题。
现有有新的问题。在liunx起动的时候，
