我是新手,好容易调通了一个程序,却写不到芯片里,总是出现如下报警: load failed. a section of your program falls into a memory region that is not writable.check your linker configuration an /memory map. 我的连接是没有问题的, memory map 可能也没问题!下面是相关的文件: 请高手给我指点指点,我卡在这里无法继续进行了!(还有一个问题就是我要写的芯片是别人写过程序的片子,不知道和这个有没有关系,如果有关系,请告诉我我怎么才能写进新程序!) 先谢谢大家! /********************************************************************/
