标题: DSP 烧写程序 进入非法中断 [打印本页] 作者: CLBuu 时间: 2022-1-10 10:36 标题: DSP 烧写程序 进入非法中断 编写dsp程序时，由于代码较长，超过片内RAM空间，所以改为烧写flash ; T& J& D: U9 N c) _ 开始烧写代码，运行程序，结果均正常；然后在此基础上添加一段代码（代码内容类似，没有错误），结果运行程序后，程序跳入非法中断 interrupt void ILLEGAL_ISR(void)，不知为何。仅仅是添加一段代码，结果出现非法中断，百思不得其解，请高手指点一下。多谢多谢。 - L4 L' p" k4 b 程序中cmd文件如下：; S3 H8 v9 s8 \

这个问题可以从这个思路走一下： W! j/ o' V( D* q- j
（1）检查一下，新添加的代码是否在某个中断内不？原因是因为中断没有执行完，异常结束了。 # S. l5 s3 F$ J. m4 k（2）找问题，首先不找cmd文件的问题。/ f- B# ?: x* }7 L
我个人见解。作者: guanshen 时间: 2022-1-10 13:11
是和程序的代码长度有关，或者是类似堆栈缓存空间不足作者: xiananUZI 时间: 2022-1-10 13:32
如果方便，可以把你添加的代码和被添加的部分，粘出来，我看一下作者: kiygb 时间: 2022-1-10 13:53
利用单步执行，看程序执行情况
