Question

Break at address "0x1fff5e8c" with no debug information available, or outside of program code. error.

I'm trying to program STM32WBR55VGY microcontroller in my custom board.

Recently, I succeed to debug my microcontroller but after one time, I can see this message on the STM32cubeIDE during debugging and the microcontroller does not work properly.

"Break at address "0x1fff5e8c" with no debug information available, or outside of program code. error."

How can I solve this problem?

    In the disassembly, this problem happens when starting HAL_Init();

    Suggests it's booting from ROM due to BOOT0 high/floating, or FLASH not containing valid image.

    M​ake sure your code sets the vector table address properly via SCB->VTOR

    Thanks for rely.

    Unfortunately, I'm not professional that can understand what you said.

    I know there is boot0 boot1 pin but I don't know how to use it and how to setup it in the STM32cubeMX and cubeIDE.

    Is there anything I can know this?

    By the way, the problem happen again even though I replaced the microcontroller.

    The pin state at boot ​is determined by your board design
