Help me with stm32f4

Hello, I am new to this forum, got interested in rusefi when I was looking to buy ms, maybe half a year ago I bought frankenso and now I finished assembling/soldering and need your help. My problem or question is simply where do you short stm32 to program it, as my board doesn't have that stm discovery board as an add-on but the stm chip and other components are directly soldered to frankenso.

Probably DFU. Jumper between VDD and BOOT0, will elaborate in a few hours

Serial bootloader? https://www.st.com/en/development-tools/flasher-stm32.html
Don't get your question, yes? I need to connect my pc with stm so i could programme the chip but on rusefi wiki I see that I need to place jumpers on the discovery board, but my problems is that I have directly soldered stm to frankenso board there is no stm discovery like in picture.

you need ST-link ...
if you dont have you may use STM32 discoveri bord which has part of the board as a programmer see on pic ...
I do not remember exactly, but it seems you need to remove two jumper (in the white circle) in order to use SWD on STM32 Discoveri as Programmer ...

Yes, this helped me to program without st-link.
