我在MC9S12XDP512上做应用开发，当应用程序编译时出现错误，提示如下：Out
of allocation space in segment RAM at address 0x2D61
开发的这个应用程序在MC9S12DP512&UC/OS-II上运行是没问题的，在s12x上面怎么就有问题
了呢？MC9S12XDP512的RAM空间是32k而MC9S12DP512的RAM空间是14k，我想在MC9S12DP512上可以运行的在MC9S12XDP512也应该没问题的，请问问题出在哪里？请版主帮忙解决，谢谢了了！作者: freescale_bjut 时间: 2008-3-4 09:35
您说的是不是prm文件啊，这个文件中S12和S12X的定义区别如下：
请问具体应该怎么修改才能解决这个问题呢？谢谢！
