STM32L053 Nucleo how to flash

[Wleon.1]

Hi, I would like to know how to flash a program to my STM32L053 Nucleo board, for now after each power cycle I need to download the program via a debugger to the board, is how do I flash the program to the board ?

Your tools should be flashing the firmware, it would be quite difficult to create a project that didn't, so more likely something in your process is wrong.

Did you set any option bytes?

How do you know your code isn't running?

Are you linking for operation at 0x08000000 ?

Try one of the examples in CubeMX for your board.​

it is targeting the ram which is 0x200000000 ++

I am using cubeMX to generate this program

Try examples in CubeL0, for instance one that blink LED/GPIO

Pick FLASH as the target​
