Hi! Where can I get schematic diagrams and PCB layout for the NUCLEO-H743ZI2?

I am having problems with the clock signal supplied from ST-LINK chip and need to exchange it with a clock signal from a stable oscillator. For that I need the layout to find the power lines and the diagram to identify jumpers. The schematic and layout of the second version (ZI2) are not the same as in UM1974 for NUCLEO-H743ZI; I need schematics for ZI2 version! Thanks!

ST's website doesn't clearly distinguish between Nucleo-H743ZI and Nucleo-H743ZI2. Just look for the board MB1364 (ZI2) instead of MB1137 (ZI) at https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-nucleo-boards/nucleo-h743zi.html#resource

and for UM 2407.

I think that is the newer one. Not very easy to follow. My ZI2 board has MB1364C board.

Wow, that was fast! I would like to thank all of you. The ST site is not very clear with distinguishing the ZI and ZI2, it actually promotes the ZI version and I was not able to find the ZI2. Now, with this help, things are obvious. Thanks again.
