Which firmware (where did you get it from, what is the filename). How did you flash/deploy it? What board are you using (is it the NUCLEO-H743ZI). How are you connected to the REPL?

There are slight differences between the H743ZI2 and the H743ZI. The mods for the ZI2 have been incorporated into the mainline code very recently.

Have you tried using two USB connections (one to the stlink port and one to the user port)? If you try to just use the user port by itself the board won't be powered up.
