STM32G030F6 BOOT0 and SWCLK shared

MKanc.1
Associate III

Hello

I have a bunch of STM32G030F6 and they are in TSSOP20 package.

I used SWD and BOOT0 pins to program L433 and want to do the same on G030F6

However, unlike same TSSOP20 package F070F6 has, G030F6 share BOOT0 pin with SWCLK.0693W00000aIgShQAK.png19th pin of STM32G030F6 is both BOOT0 and SWCLK.

How does one program it using SWD? Do i need another method? I want to build a small devel board for future projects so i need to program both blank and pre-programmed chips.

I might be missed some parts from datasheet i apologize if i did.

Presumably it only samples the BOOT0 state at power-up/reset. So you'd only need it in a steady state briefly, and then use the SWD functionality.
