nucleo_h745zi_q_m7 won't flash hello_world

[codewitch-honey-crisis]

I've followed the docs here on 4 brand new nucleo_h745_q_m7 boards and get the same result on each

https://docs.zephyrproject.org/latest/boards/arm/nucleo_h745zi_q/doc/index.html

init
Info : STLINK V3J5M2 (API v3) VID:PID 0483:374E
Info : Target voltage: 3.304000
Error: init mode failed (unable to connect to the target)

This is either a bug in the documentation or a bug in the flashing system. Which is it?

I do not have that nucleo_h745zi_q_m7 for testing
I can just suggest :

1. to upgrade the STLINK (with STM32CubeProgrammer) of the nucleo board)
2. to check there is no other connection (like STM32CubeProgrammer) to the target board
3. check the hw and sw config of the LDO/SMPS power supplies (see below UserManual)

STLINK:

UserManual:
The stm32h747i_disco board has a hw configuration that could lock the board because of power supplies when hw and sw config mismatch. You can find clarification in the UserManual UM2488 of the disco kit.

I confirm using an up to date STLink is okay for me with this board.
