TI中文支持网如图，CC430的收发程序，等时间长了之后，程序就飞了，一直在reset_vector中不动了，不知道是什么情况。
Hardy Hu：
请把代码发上来看一看，程序跑飞的原因很多种
Peter_Zheng：
回复 Hardy Hu:
这种问题在CC430里一般都是由于数组越界引起的，建议检查你的收发双方的数组长度定义。

/******************************************************************************
* CC430 RF Code Example – TX and RX (variable packet length =< FIFO size)
*
* Simple RF Link to Toggle Receiver's LED by pressing Transmitter's Button
* Warning: This RF code example is setup to operate at either 868 or 915 MHz,
* which might be out of allowable range of operation in certain countries.
* The frequency of operation is selectable as an active build configuration
* in the project menu.
*
* Please refer to the appropriate legal sources before performing tests with
* this code example.
*
* This code example can be loaded to 2 CC430 devices. Each device will transmit
* a small packet upon a button pressed. Each device will also toggle its LED
* upon receiving the packet.
*
* The RF packet engine settings specify variable-length-mode with CRC check
* enabled. The RX packet also appends 2 status bytes regarding CRC check, RSSI
* and LQI info. For specific register settings please refer to the comments for
* each register in RfRegSettings.c, the CC430x613x User's Guide, and/or
* SmartRF Studio.
*
* M. Morales
* Texas Instruments Inc.
* February 2010
* Built with IAR v4.21 and CCS v4.1

这是程序，而且当跑时间长了后会出现

应该不是，我一直看着数组，后面数组的后面几位一直是0，没有动过，只是一直会出来

回复 ye jin:
你的stack快满了，运行时有可能stack溢出，需要优化程序结构，比如把数组长度减小，或者修改CMD文件，给stack多分配一些空间
zhang zhen：
朋友问题解决了吗？
我也遇到了和你一样的问题，也是进入了 reset_vector 中
请问你最后怎么解决的！
谢谢！
