Hi everyone,
I’m currently working with the LPCXpresso55S28 board and have encountered an issue that I hope someone can help me with. I’ve developed a simple test application that makes an LED blink. When I build the binary normally and flash it using LinkServer, everything works perfectly, and I can debug without any issues.
However, when I adjust the project settings under MCU Settings and define the flash areas as shown in the attached image, the application can still be flashed without errors, but the LED no longer blinks. Furthermore, I am unable to debug the application after making these changes.
Here are the details of my setup:
- Board: LPCXpresso55S28
- IDE: MCUXpresso IDE v11.9.1 [Build 2170] [2024-04-19]
I have also attached output of the console, when trying to debug.
