请求帮助，这是什么原因？

duzhig

你的ramdisk有问题 /dev下没有  console

这个 问题 已解决，忘了mknod console c 5 1了，
但是又遇见了新问题了，错误如下：

到此就停住了 ，且上述是什么原因导致的Division by zero in kernel？
        望高手指点！！
                     谢谢！！

duzhig

Division by zero in kernel不影响系统使用 主要是MCKR初值没有赋，你取消skyeye没模拟外设支持，只保留串口相关的试试

qq425887742

怎样操作才行呢？
      谢谢！因为本人是一个 新手
