Yes. SPI clock is configured as 8MHZ.
I have corrected CCR setting for memory mapped by using 0xEC but it throws same
error.
I have commented out "setparms" to verify the memory mapped mode works but it
shows error as below

Not sure what is the problem in reading external flash1 device id and continue
with "setparms"
As i said previously, there was an issue in debugging from internal flash and
it got fixed with a fix(PG bit clear before the Internal flash write), Would it
be any similar issue in openocd source for external flash?

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

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
