TI中文支持网嗨，目前使用F28374S，在測試於APP程式理面將一個扇區給清除，但是目前測試時發現有機率進到下面的副程式時會失敗，導致MCU重啟
目前有設置收到清除命令後750 uS會做清除動作，也就是下段指令，等待1.5S 後 Mcu重啟，重啟後會到IAP程式來判斷扇區是否有被清除。
不過測試上百次總會有那麼幾次發現有奇怪的問題，因此用示波器抓問題，剛好在750uS時就Reset了可以確認是下段指令有問題。
不曉得下面這段程式會有哪個部分造成此問題嗎?

Green Deng：你好，抱歉没有看明白你的问题。你是说，APP执行上述程序的时候会发生执行失败。收到命令的750us之后程序没有清除flash的某个扇区，而是直接Reset芯片了？

嗨~你好
是收到命令後的750us執行上述程序，就會Reset，依照扇區沒有被Erase的結果，應該是跑到這行MCU就被Reset了
oReturnCheck = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, (uint32 *) Erase_address);

目前這個問題有解嗎？
