TI中文支持网程序结构是，CC1101空中唤醒模式，主程序LPM3模式，CC1101接受到信号产生中断1，唤醒MSP430，在主程序中进行信号接受处理，接受完毕后再次休眠，CC1101有在定时器中定时校准频率，现在出现的问题是，大部分时间程序运行很正常，但是在运行几天以后，偶尔在接受信号以后，程序里的全局变量数据错乱，这几个全局变量是写在FLASH中的，发生错乱以后，再从FLASH中重新读出数据，数据是正确的，判断错乱应该是内存溢出导致，请问有没有什么方法可以解决这个溢出问题？

Viki Shi：
数组过大可能会导致内存溢出，你排查一下。另外，MSP430的问题建议发布到如下板块：
e2echina.ti.com/…/
user6109087：
回复 Viki Shi:
INT8Uleng =35;//
INT8UModeChangeFlg=0;
INT8U RxBuf[27]; //改为全局变量
INT8U CC1101_TxBuf[33];
数组设置的应该也不大吧
