The connector and silk-screen suggest it is a 20-pin JTAG header, would connect to an ST-LINK/V2 or J-LINK type pod.

sorry, but what is ST-LINK/V2 or j-LINK
2019-12-18 02:05 PM
How to find out if it is ST-LINK or J-LINK?

Either, should I Google this stuff for you?
It is a header you'd plug the aforementioned debug pods into.
Perhaps you could refer to the schematic for your board, of docs from its manufacturer.

Thanks. The Eng'r working on this quit just gave me the board with no schematics just block diagrams. So, I don't know which terminals of the MCU are used for programming the MCU. Any help appreciated.

I DO HAVE THE JTAG pin #s if that helps

Can the functions of JTAG be programmed in the MPU? Or does JTAG have to be a separate HW device?

Usually it is a separate device. Is Google blocked in your school or workplace?

Thanks. Thought this was a helpful site. Yes I did google but no clear cut answer. I can show you my schematic where the JTAG is implemented in the MCU, hence I was not sure
