1.如何打开一个工程？
一般工程文件的所在路径为：ZStack-CC2530-2.3.0-1.4.0\Projects\zstack\Samples\SampleApp\CC2530DB
打开后可能会出现下面几个对话框，这是由于IAR版本过高导致的，不用管，一里路yes\确定下去就好了。
打开工程后，在左边我们可以看到一个workspace，虽然有很多文件夹，但我们重点关心的主要是画箭头的几个文件，如下图：
从上到下主要包含了：用户应用层代码、zstack配置、main函数。
然后我们右键工程，选择 Rebuild all对整个工程进行编译。
2.常见报错
Error[e46]: Undefined external “?V1” referred in AF ( D:\code\MCU\cc2530\air_sensor\Projects\zstack\Samples\SampleApp\CC2530DB\CoordinatorEB-Pro\Obj\AF.r51 )
针对这类报错，我们右键工程，选择Options，并将其中的number of virtual改为8，如下图所示：
这时候在编译，发现还是会报相同的错，这还是IAR版本的锅，我们再在Projects\zstack\ZMain\TI2530DB目录下找到chipcon_cstartup.s51文件
**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
**
复制下述代码，替换chipcon_cstartup.s51文件中的全部内容，重新编译即可文章来源：https://www.toymoban.com/news/detail-756263.html

这种报错提示：分配的空间大小不够，我们首先找到TOOLS文件下的f8w2530.xcl文件，利用CTRL+F找到报错的那一项，如下图：
对下面的代码进行修改，将空间多分配4个字节即可，如下：文章来源地址https://www.toymoban.com/news/detail-756263.html
-D_RAM_CODE_FLASH_END=(_RAM_CODE_FLASH_START+0x26)
