[已解决]KE02使用KDS学习MQX lite链接不过，提示`m_data' 溢出

在FRDM-KE02Z开发板上，学习MQX。按照DWF13_APF_ENT_T1286_Ch.pdf文档（）的步骤，一步一步的使用KDS中的PE操作，最后编译工程，提示如下：

从提示看出，是链接时m_data段溢出，然后我就在PE中查看了连接设置，见下图（也可以直接修改Project_Setting-Linker_Files-ProcessorExpert.ld）

以上配置都是默认生成的，
栈和堆都是0x100，不知道应该减小到多少？太小了MQX应该无法执行吧？

试着将第二张图中的
stack size  改为最小的20
heap size 改为0

可以了

OK,以后有问题再交流！
