使用MCUexpressoIDE软件调试LPC55S66板子时遇到程序异常终止的问题

[melon]

 在MCUexpressoIDE中使用NXP官方LPC55S69MDK包中的电亮LED灯示例程序，连接板子后debug，在确认电源、仿真器无误的情况下运行例程会弹出“Break at address "0xeffffffe" with no debug information available, or outside of program code.”的窗口

In the MCU expressoIDE, use the example program of the power LED light in the NXP official LPC55S69MDK package. After connecting the board, debug it. After confirming that the power supply and emulator are correct, running the routine will pop up a window saying "Break at address" 0xefffffe "with no debug information available, or outside of program code

Hello @melon 

If your chip is LPC55s66, please first crate a project based on LPC55s66, then test download and debug, check whether it can work well.

Yes, the MCU I am using is LPC55S66, but since the target board I am using is not a development board, I can only use the demonstration routines in the SDK of LPC55S69. And I downloaded the SDK for LPC55S66, but there is no option for LPC66S66 in the "import SDK examples" section.
