IAR编译zigbee出现问题Undefined external "?V1" referred in AF

Error[e46]: Undefined external "?V1" referred in AF ( C:\Texas Instruments\Z-Stack Lighting 1.0.2\Projects\zstack\ZLL\SampleApp\CC253x\RouterEB-Pro\ 
Obj\AF.r51 )

解决问题如下：

原来这个是IAR版本的问题引起的，参考这个 http://supp.iar.com/Support/?Note=98110
按照参考里面说的解决方法，将workaround.s51 文件加到工程里（我是加到了C:\Texas Instruments\Z-Stack Lighting 1.0.2\Projects\zstack\ZMain\TI2530DB目录下，注意要在工程里该目录右击“add file ... ”），然后再次rebuild后，原来的问题没有了，但是出现了第二个问题，

“Error[e16]: Segment ISTACK (size: 0xc0 align: 0) is too long for segment definition. At least 0xe more bytes needed. The problem occurred while processing the segment placement command  
"-Z(IDATA)ISTACK+_IDATA_STACK_SIZE#08-_IDATA0_END", where at the moment of placement the available memory ranges were "IDATA:4e-ff" ”

于是又查到 http://e2e.ti.com/support/low_power_rf/f/538/p/303921/1061753.aspx
根据以上列出的这个帖子里面的 Luis Johnson （就是贴出了一大个图的那个）给出的解决方法，将numbers of virtual registers 由16 改为8个，再次rebuild，就OK了，没有报错。

workaround.s51文件内容如下：

第二个问题如下：
