下載程式的時候老是提示“Could not stop Cortex-M device! Please check the JTAG cable”，點完確定后，出現另一個提示”Error: Flash Download failed - Target DLL has been cancelled“.而且JLINK還一直閃紅燈，不知道為什么。

檢查一下jlink是否接好，mdk5魔術棒-debug里是否選擇了jlink，settings里flashdownload里是否勾選了flashuj5u.com熱心網友回復：
這些都設定好了，沒有問題的

對Option中的c/c++中進行1級程式優化選擇、勾選“Optimize for time”，、勾選“One ELF Section per Function”;勾選Option中ASM的“Thumb Mode再不行）。解決是這樣解決的，出問題的時候都是設定了就換jlink吧c/c++和asm.uj5u.com熱心網友回復：

朋友你好，還是用mdk燒錄嗎？步驟能說詳細一點嗎，我才接觸這方面知識
