I was trying to write a small firmware to keep the LD9 Orange LED steady ON, instead of blinking in STM32CubeIDE. I could able to flash into CM33 core using the debugger and able to debug. When I disconnect debugger, it still remain ON.
But once I reset the board, the CM33 firmware is gone and LD9 again started blinking, as if my firmware is over written.
Any solution?
