[OpenOCD-devel] Stange behaviour with STM32F7 and freshly built OpenOCD

[Rocco M. G. <roc...@gm...>]

Hi all,
this is the first time I am writing to this mailing list and I wasn't able
to find such a list of rule or similar so I ask you to notice me if I am
doing something wrong.

I have built OpenOCD from GIT master using MSYS2 under Windows (Open
On-Chip Debugger 0.10.0+dev-00746-g8f518d359 (2019-03-14-17:18)). It works
like a charm with many of the targets I usually use. But I have a problem
with STM32F746G. OpenOCD is able to recognize the target but is unable to
flash and run a .elf file.

The procedure is executed using an Eclipse-based IDE known as ChibiStudio.
The procedure was working with all the previous versions of OpenOCD built
using the same method i.e. MSYS2 + packagebuild from Alex Pux (https://
github.com/Alexpux/MINGW-packages.git)

Anyway, I have collected some logs using -d3 option maybe this would help
you to detect some sort of bug.

Aside to find out a solution to provide a working copy of OpenOCD to the
ChibiOS community, I hope this could be helpful to OpenOCD developers to
improve reliability of this amazing project. I am not inside all the
mechanism of building and methodologies used to debug.
Anyway, let me know if I can do something else to help you.
Ciao,
RM
