代码贴上一下，我也刚学C8051F，看看能不能编译调试过去。

可以初步结贴了(虽然问题还没真正解决!)
简单说明一下:
   出现1K代码后程序一直在STARTUP.A51内死循环是因为我在一个工程里面又用了KEIL UVERSION4编译,同时又用了C8051FXXX IDE编译,估计造成文件使用上的冲突而出问题的!!希望大家再编译的时候要严格分开(作为不同的工程包,但可以同时使用同一个C源文件)!


其实真正的问题是没解决,也就是从 STARTUP.A51中的 "LJMP    ?C_START"跳到主程序的开始位置总是有点不吻合,造成程序在某特定位置作死循环!!!我还会继续关注此问题,总感觉破解的KEIL UVERSION4还是有问题!!


希望此问题也能引起各位高人的关注!!看看大家在开发的时候对此有什么共鸣!!


有兴趣的可以看看，我已经附上了

恐怕CODE长度大约 2085 BYTE就有问题的！！？

河蟹版的编译没什么问题。无2K限制提示。
