Dear ST community member,

I am new to ST platform.

I am using STM32G030C8T6 Development board from 7 Semi and ST Link V2.

Dev board link: https://evelta.com/7semi-stm32g030c8t6-arm-stm32-mini-development-board/?srsltid=AfmBOorI6XBlJ_AMXNVV184OhO-lB02AFODj1611j8H62qR2M0FZkmF9

Connection: 

• dev board USB: power
• dev board RST: NSRT or pin15 of ST LINK V2
• dev board SWDIO: pin 7 of ST LINK V2
• dev board GND: pin8 of ST LINK V2
• dev board SWDCLK: pin9 of ST LINK V2
• dev board 3.3: Not connected

Please guide me where I am doing wrong.

Thanks in advance

Regards,

Anand Sagar

STLinkV2 exist in ISOL variant , then 3.3V require to connect...

Next issue maybe is DFU bootloader try change reset behaviour to connect under reset

also validated the pins connection, all are fine.

Use CubeProgrammer , connect (set: software reset), show pic, what its telling.

I am using original ST LINK V2 from st.com, yes after connecting the 3V3 to pin 1 of the ST Link, started working with default debug settings.
