SDK调试遇到DataAbortHandler问题。 运行后不显示结果,debug模式下发现进入DataAbortHandler异常函数。程序中存在大数组。 原因:SDK默认的堆栈为1024bytes,需要将堆栈调大。 修改方法: 解决:对application中src下的lscript.ld双击,对stack and heap sizes进行修改,改成较大尺寸。

If there is no MMU, the Data Abort handler must report the error and quit. If there is an MMU, the handler must deal with the virtual memory fault. The instruction that caused the abort is at lr_ABT-8 because lr_ABT points two instructions beyond the instruction that caused the abort....
