How to erase flash before programming with STM32CubeIDE [Solved]

Is there someway to do this with stm32cubeide?

For my specific use case I am storing configuration data on last page of flash (currently working on figuring out how to erase it so i can rewrite it in software), but I would also like to be able to configure it by reprogramming it. I can check that the page is empty and write settings to it, but I haven't found any way to erase it with stm32cubeide, I need to open the st link utility in order to erase the flash as far as I can tell.

There are a few ways of doing it. For example, you can either call cube programmer CLI and run a mass erase as a pre-build step ${cubeide_cubeprogrammer_path}/STM32_Programmer_CLI.exe

If you use that way it's important that in the debug configuration under "Main" tab that you don't have auto build disabled because then the pre-build step will not be called.

You can also go to the startup tab in the debug configuration and add "monitor flash mass_erase" as an Initialization command.

Thanks, somehow I had tried to write in the initialization commands section, but I hadn't thought to include the word "monitor" in my command, so it only gave errors.
