Thanks for the quick response.
I am using two similar boards with same firmware. In that I'm able to debug
from one board but could not debug from other board and it throws below error.
Error: auto_probe failed
in procedure 'reset'
in procedure 'ocd_bouncer'
in procedure 'ocd_process_reset'
in procedure 'ocd_process_reset_inner' called at file "embedded:startup.tcl",
line 248
in procedure 'stm32h7x.cpu' called at file "embedded:startup.tcl", line 382
in procedure 'ocd_bouncer'
It exactly fails at "stmqspi setparms 2 IS25LP512M 0x4000000 0x100 0x13 0x12
0xc7 0x10000 0xDC"
FYI: Both the boards are working fine when i try to flash through ST Cube
programmer + External loader which suggest that there is no defect in hardware.
I have attached the .cfg file and log files for your reference.

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

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
