如图，创建全局变量的数组，提示.ebss不够，像注释中一样加大内存，还是一样出错
mainandcmd.zip
需要整个工程文件吗
您可以尝试在链接器命令文件上，尝试在.ebss部分中使用其他大型RAM，类似以下语句：
.ebss : > RAMGS2| RAMGS3, PAGE = 1
您可以使用CCS内的View->Memory Allocation来查看memory的使用情况
software-dl.ti.com/.../ccs_memory_allocation_view.html
你好，采用了你建议的操作后，结果如下
另外，工程文件如下:
DAC_SIN.zip
请使用下面的cmd文件，测试ok
