C6678跑VLFFT例程，使用了sys/bios，提示LL2不够用，怎么设置更大

网上查过是LLS太小， 要在cfg中使用pragram sect_map调整memory存放的section段

http://www.deyisupport.com/question_answer/dsp_arm/c6000_multicore/f/53/t/22209.aspx

我看了一下cfg文件：

Program.sectMap[".internalMEM"]={runSegment: "L2SRAM_1"};
Program.sectMap[".externalMEM"]={runSegment: "DDR_1"};
Program.sectMap[".sharedMEM"]={runSegment: "MSMCSRAM_2"};

只有这里有设置， 是把internalMEM作为L2SRAM_1的意思吗？

还是不懂要怎么弄？谁能指导一下。谢谢了。
