关于编译不通过的问题，请求分析和帮助

请教各位，我在build一个工程的时候，报出了错误。如下

<Linking>
"./configPkg/linker.cmd", line 170: error #10099-D: run placement fails for

好像是L2SRAM不够用了，还是什么。我查卡了一下RTSC的platform设置，设置的存储区是够用的。然后查看了一下.map文件，说

上面说是有很多很多数据块和程序块没有成功分配内存。我知道使用SYS/BIOS时候，这些设置SEGMENT, SECTIONS的加载和分配内存的linker.cmd文件是自动产生的，不能修改。我想问的是，编译器是怎么分配内存的，如果我想改变.cmd文件里面的配置，应当在BIOS的哪里修改？

先谢谢各位解答的好心人了。

    link错误是不能产生map文件的，
    你的L2 size设置也太小了，0x26000 才150K, 6678的L2最小也有500K

    谢谢你的回答，James Li。

    这个程序是当时Ti培训时候给的例程，所以关于内存的分配我是按照原来设置来的，

    我在TI的英文网页里咨询时候，人家说是我的Program.sectMap可能没有设置对，也许是这个原因，但不确定。我在.cfg文件里没有搜索到关于.cint,.const,.stack等内存配置的信息，是不是这里出了问题，要添加一下？

    cinit, const, stack是TI默认的memory section，分别用于存放全局变量的初始数据、及全局常量，定义堆栈，具体可以看SPRU187编译器手册中的描述。

    错误提示LL2不够用，你可以在cfg中使用pragram sect_map调整memory存放的section段。
