STM32H747I-DISCO "Discovery kit with STM32H747XI MCU" -- ST-Link

The board has ST-link "built in" via a STM32F723IEK6 chip dedicated to that purpose. Just for the record, the F723 is a Cortex-M7 running at 216Mhz with 512K of flash and 256K of SRAM. It even has 8K each of I and D cache.

Grabbing a micro USB cable and plugging it into my linux system, I see:

So, we see 3 things. The third (mass storage) surprises me. It contains 3 files: 
-r--r--r--  1 tom  tom    65 Mar 26  2019 DETAILS.TXT
-r--r--r--  1 tom  tom   512 Mar 26  2019 GETSTART.HTM
-r--r--r--  1 tom  tom   512 Mar 26  2019 MBED.HTM
The DETAILS file has: 
Version: V3J10M3
Build:   Nov 19 2021 16:55:14
The GETSTART file has a (broken) redirection link to: The MBED file has this link as a "shortcut", which has useful diagrams and information
