ST Link V2 and V3 VS STM32G0B

[grisom13]

Hello,

I have a STM32G0B1KBU3N MCU for my USB-C PD board. I am a new with this so learning. I am currently finished assemble my own PCB and have some issue with programming the controller. I can program controller with ST link V3-minie but have Zero luck to go connect with ST LInk v2. Is my controller supports only V3 hardware? I saw in the Programmer menu with V2 hardware there is only 4 kHz frequency and V3 hardware offers 8 kHz (same as controller internal clock) am I right? Thank you.

Show a schematic of your STM32 connections.

1. In your schematic I see no RST connection to the ST-Link 

2. Is the Jumper JP9 for 3.3V to ST-Link closed?

3. What do you mean with "St Link v2"? Is it a genuine ST-Link from ST or some fake "ST-Link v2 mini"?
