Hi @LicinioFortunato
First please avoid to open issue for this. Discussion or forum are better place for this.

It seems You can use a STLink to program it as we saw DIO, CLK and NRST pins available. Or you can probably flash over Serial, refer to https://www.st.com/resource/en/application_note/cd00167594-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdf

Sorry. Next time I will open a discussion. I do not have st-link. Only UART, and USB converter (ch340)
