The id will be checked just before the first comand touching the flash is
executed (setparms, mass_erase, ...), that's the auto_probe. Yes, it would be
nice if you could check whether commenting out the read_id helps.
But: Please don't use the old version. The updated patch had been merged
already, so pull head as described on
http://openocd.org/doc-release/doxygen/patchguide.html (only step 2) and build
it.

** [tickets:#290] QSPI debugging is not working in some stm32h753 mcu**
**Status:** new
**Milestone:** 0.10.0

Hi All,
i have two custom stm32H753XI + NOR QSPI flash (IS25LP512M) board. I am able
to debug in one board successfully but in another board it fails and even it
doesn't show the external flash ID of the chip. However i'm able to program
both the boards using st cube programmer with external loader and it is working
fine in normal mode.
In not working board, initially i faced issue in debug from internal flash
itself. And i found a fix from internet where they suggested to add PG bit
clear before the Internal flash write. I did the fix on top of
http://openocd.zylin.com/4321 change, then i was able to debug from internal
flash. But facing issue in debug from QSPI flash.
I have same cfg file which is working in one board and not working in another
board.
Please anyone help me to resolve the issue.
Regards,
Shahul
