想做s3c6400平台

如果按照摩尔定律来讲，2410、9200这些芯片早该被淘汰了，不过如果真这样，我们这些工程师就累死了。这也是嵌入式和pc有区别的地方之一。从培训教学的角度看，随着这些资料的普及，也是时候升级换代了。

最近和朋友商讨如何选下一个平台的事宜。一个朋友对freescale的产品不放心，另一个朋友极力推荐ti的omap3530，也是火热的contex A8。不过想来想去，我还是觉得三星的似乎在国内更受热捧。价格也不高。

基本上就决定做一个基于S3C6400的板子。看了一下uboot和linux内核，基本上都已经支持了，所以移植起来还是很有信心的。Google一下现在的市场，也有一些厂家有了平台推出，不过价格都不菲。但是大多提供了wince的支持，而linux支持的少一些。我想，我们计划做的这个板子能够提供更多的软件资源，特别是android要移植好，估计很多人喜欢这东东。
