在使用協議棧的時候，編譯程序總是報這個錯，差找了好多文章，發現都是CSDN上的，今天決定寫一篇這個錯誤記錄：
第一個錯誤：
Error[e16]: Segment ISTACK (size: 0xc0 align: 0) is too long for segment definition. At least 0x9 more bytes needed. The problem occurred while processing the segment placement command
版本原因，只需要 Project -> Options -> General Option -> Target，在Target標簽中找到“Number of virtual”，原來默認為16，修改為8
第二個錯誤
Error[e46]: Undefined external "?V1" referred in AF
該錯誤是老版本代碼在新版本的IAR上運行出現的，只需要替換掉原來的ZStack-CC2530-2.5.1a\Projects\zstack\ZMain\TI2530DB下的chipcon_cstartup.s51文件即可
鑒於很多文章介紹都是在CSDN上下載，其實在官網上也可以下載，然后按照下面步驟來即可

首先替換原文件，然后將下列代碼（在下載的文件當中也有）插入到該文件末尾，記得刪除掉原文件末尾的END
