安装了高版本IAR，9.1以上，主要出现过如下三个问题：
问题1.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 )
问题2.
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-_IDATA_END", where at the moment of placement the available memory ranges were "IDATA:4e-ff" 解决方法： 1.：Change number of virtual registers to 8 2.替换C:\Texas Instruments\ZStack-CC2530-2.5.1a\Projects\zstack\ZMain\TI2530DB下的chipcon_cstartup.s51文件 ，文件链接在结尾 再次点击 rebuild all 即可消除 问题3. Error[e16]: Segment RAM_CODE_FLASH (size: 0x27 align: 0) is too long for segment definition. At least 0x4 more bytes needed. The problem occurred while processing the segment placement command "-Z(CODE)RAM_CODE_FLASH=_RAM_CODE_FLASH_START-_RAM_CODE_FLASH_END", where at the moment of placement the available memory ranges were "CODE:39ddd-39dff" 解决方法： 根据上面说的，RAM_CODE_FLASH需要再扩大至少4个字节，打开Tool-fw82530.xcl文件，将RAM_CODE_FLASH_END的值再增大至少0x4,如下 -D_RAM_CODE_FLASH_START=0x39DDD -D_RAM_CODE_FLASH_END=(_RAM_CODE_FLASH_START+0x22)将0x22改为0x26，具体值视错误提示而定。再次rebuild all即可消除错误chipcon_cstartup.s51下载地址 链接: https://pan.baidu.com/s/1nvLWQjJ 密码: esv6
