Please tell me how to load the project into stm32

[ark2]

I ran stm32 with cubemx and iar to execute the project, but I have to remove the st-link line and execute it

If I take out the line, the project can't be executed, so how can I only connect the board and power to run the project?

download active application -> download file

I tried it the above way, but it doesn't work when I turn it off and on

If this is a custom board make sure BOOT0 is pulled low.

H​ave places where it dies in while(1) loops silently output more useful reporting or set GPIO or LEDs so you can debug the issue without a debugger attached.

Downloading but server source did not work.

Since you wrote the answer, I'll post that it's the best.
