Re: [OpenOCD-user] Nucleo-H745ZI configuration?

[Liviu I. <il...@li...>]

I did some further investigations, and in the end the board was recognised by openOCD.

However something is weird, the board works only when connected to a USB3 port, and sometimes it fails the first attempt and requires a retry.

I also installed the latest STM32CubeProgrammer and updated to the latest firmware (the on-board programmer is a STLINK-V3).

The connection looks like this:
