Hi i am designing my stm32f401rbt6 board i have stlink v2 which is common and cheap :
I used blue pill (stm32f103),programming is done with 3.3v,gnd,swclk and swdio.So can i do same process with stm32f401
i tied the swclk swdio 3.3v GND to programmer`s pins but i cant detect my MCU by st-link v2.i am not sure where is my mistake
power line is under the board and it is so complicated but i checked every pin multiple times.
