STM32L476 中斷問題或編譯問題
本帖最后由 天天地天天 于 2018-3-23 10:21 编辑各位大大們一個問題，我圖片上的紅色圈圈。再我每次運行程序時，每次都會一直停在我紅色圈圈處的位置，然後就一直停在這個點，想問問大家有沒有人跟我一樣的問題，這會是什麼原因造成? 最後是如何解決的呢?
P.S.停在startup_stm32l476xx.s裡的第405行
函数名对不对？ 本帖最后由 wenyangzeng 于 2018-3-22 16:05 编辑
出现硬件故障、堆栈溢出等致命故障。应该先查找晶振电路起振否、系统时钟配置有误导致超频等等。 我主振是使用內振的80M，32k是使用外振的單純給RTC使用，初始化設置都有過，但進入while loop後跑完2次，就直接進到這裡沒出去了..... 这个肯定是程序问题啦，一点点注释跑起来看看还有这个错误吗 本帖最后由 天天地天天 于 2018-3-22 16:53 编辑
回大大有的!
我有註釋掉一條程序，後他就不會卡住了，但是我找不到條程序哪裡有問題......
P.S.那條程序是ST所撰寫LoRaWAN的控制程序，我沒有做變動單純移植程序過來，變換腳位而已。
所有的程序設定都是跟著ST給的範例程序設定去設置的!

不清楚怎么回事。
你的程序跑到中断服务中出不来了。从237行到405行，全部是Default_Handler，外设中断向量表及中断服务跳转地址。
程序指针怎么跑进来的，而且还是跑到最后的，值得研究。
你都开什么中断了？如果列表中的中断都没开，那有可能是堆栈溢出了，或者是别的异常跳转。

程序触发了一个你没有捕捉到的中断。检查一下该写的中断处理函数你写了吗？ 感謝各位大大們，小弟我找到了!!!
我真的有一個中斷名子沒設對......:L
