stm32f030f4 while writing flash target not responding and which is the proper address to write

[Mk.11]

[EJOHA]

Please try to create an empty project for this STM32 device in STM32CubeIDE. Then compare the linker script file (.ld) file with the one in your project.

Is it possible to debug this empty project on the board?

You can try to debug both with ST-LINK GDB server and OpenOCD.
