接触2812没多长时间,写了一段代码后编译出现如下错误:>> error: can't allocate .text, size 000012db (page 0) in PRAMH0 (avail:
00001000),网上找资料说的是代码长度超出RAM空间了,有几种解决办法,1、精简代码,直至不会出现此类错误,2、增加外部RAM,3、修改cmd文件,把代码放到不同的text段内,前面两种方法暂时不方便实现,第三种方法网上也有部分介绍,但是CMD文件不太一样,不是太理解,所以一直没能解决问题,不知道有谁遇到过此类状况,分享下经验,怎么配置CMD文件,万分感谢。。。
我的SRAM.CMD文件如下:

阿莫论坛20周年了!感谢大家的支持与爱护!!
该献的血还是要献的。你不献他不献。难道让我去献? --- 出自坛友:lovejp1981
