What is the HSE value?

It is 8MHz. Should be ok now.

The flash page erase size is 128k, so the bootloader must take that much space, and the minimum filesystem must also be 128k.

This is probably related to #11138 for the adapted flash block size on the H7A and H7B devices
This works on my NUCLEO-H7A3ZI-Q boards. It was mainly adapted from the STM32H7B3I_DK board files.
There are probably a few peripherals activated that are not available at the NUCLEO board.
The PLL settings are taken from the suggestion at: https://forum.micropython.org/viewtopic.php?t=7930
