@copilot how do I connect J2 and U2?

Sure, I can help you with that. J2 seems to be like a debug header with JTAG pins, and U2 is an ARM microcontroller (STM32H753IIT6) which typically has JTAG interface for debugging. The standard connection would be:
  • Connect J2:JTCK to U2:JTMS
  • Connect J2:JTDI to U2:PE2
  • Connect J2:JTDO to U2:PE1
  • Connect J2:JTMS to U2:PA15
  • Connect J2:NJTRST to U2:PB4
  • And finally, Connect J2:RESET to U2:NRST
Please note that boundary scan/Debug pins (JTMS, JTDI, JTDO, JTCK) on STM32 microcontrollers can also be on pins named SWDIO, SWCLK, SWO, and NJTRST, if available.
Also remember to connect VDD and GND pins of both the components correctly.
The exact pin mapping may vary depending on whether the STM32 microcontroller is configured to use JTAG or SWD (Serial Wire Debug) for debugging. The pins I've suggested are my best guess based on the naming conventions, you'll want to confirm the correct pins using the datasheet for your specific microcontroller.
