flashing issue with ST Nucleo board H745ZI-Q

[vagotec]

Hi,
there is a bug with ST Nucleo H745ZI-Q. The same issue (Ticket:#29732). But the solution does not work.

openocd.cfg
source [find board/st_nucleo_h745zi.cfg]

reset_config srst_only srst_nogate connect_assert_srst

$_CHIPNAME.cpu0 configure -event gdb-attach {
echo "Debugger attaching: halting execution"
reset halt
gdb_breakpoint_override hard
}

$_CHIPNAME.cpu0 configure -event gdb-detach {
echo "Debugger detaching: resuming execution"
resume
}

Application build is ok
run on Hardware not ok (flash)

@vagotec can you check that this isn't fixed with #30417 ?

Hello erwango,
unfortunately I get another error now.
my changes in relation to this document: https://github.com/zephyrproject-rtos/zephyr/pull/30417/files/768126367154828ceecab4998c712bcf361eab7a

echo "Debugger attaching: halting execution"
gdb_breakpoint_override hard
}

$_CHIPNAME.cpu0 configure -event gdb-detach {
echo "Debugger detaching: resuming execution"

}

Due to the use of connect_assert_srst, running gdb requires

to reset halt just after openocd init.

rename init old_init
proc init {} {
old_init
reset halt
}

@vagotec It seems you're using sdk version zephyr-sdk-0.11.4.
Latest beta version (0.12) includes several additions/fixes on h7 support on openocd. Would you mind upgrading to latest SDK and have a new try ?

[vagotec]

Hello erwango,
i tried with Zephyr SDK 0.12.0 Beta-3: https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.12.0-beta-3 and the same configuration.
i still get errors:

[erwango]

Is is possible not to shout :-) ?
Ok, thanks for the additional test. Well this is strange, as I have no issue with the same board on my side.

Would you be able to describe exactly the procedure that doesn't work (flash/plugg/unplugg, ...).
An idea might be to start from a clean sheet and start by fully erasing the flash using STM32CubeProgrammer.

On my side, I'll have few more tests and get back to you. Likely next week, though

[erwango]

@vagotec I just had a try this morning and everything works fine on my board.
Please provide more information on the steps to reproduce and use west -vvv when running you commands to provide more hints on what is going wrong.

[vagotec]

Hello Erwan,
After your comments and tests, i ordered a new board and re-tested everything. Now everything works fine.It's hard to believe that my new (old) board was broken (defekt from factory).

Thank you very much for your efforts (Thanksssssss)

[erwango]

That's a relief !! :-)
@vagotec Thanks for the heads up! Closing the point.
