ICE跟MCU中間要跑的資料量很多又很快,你的版子上的線路沒設計好的話,可能會被雜訊影響導致資料錯誤,不然你可以試試step跑看會不會出現同樣狀況

參照：
引線長度包括PCB上面的路徑喔。尤其是自己Layout的板子特別要注意。

這個也有時會出現有時又好好的.....

我用的是REAL ICE 接ICSP 再連接MCU 有相關需要注意的嗎??
RE你連接線有問題或是太長導致干擾~~所以電路上任何線都需注意長度嗎?還是單純只是ICE跟MCU間的線距??

沒遇過。Real ICE 發生此種狀況奇說明如下：
The MPLAB REAL ICE in-circuit emulator and the target device are out-of-synch with each other. Select Reset and then try the action again. Ensure that the cable(s) used are of the correct length.
