Option Byte Programming failed

[HSpre.1]

Good Day.

I have created a board and some program easily through SWD port and some struggle.

The error i am getting In STM32CubeProgrammer is:

Just need to put me on tracks to be able program the chip

The fresh install:  11:51:56 : STM32CubeProgrammer API v2.7.0 same error

Hi LucHardware

My problem is/was almost certainly linked to connector used on my product. I use an industrial circular connector. When I bypass circular connector by soldering programmer wires directly on pcb programming works much better and debugging works.

My solution is to simply set programming speed to 100khz and then I could program all my 270 production run.

4000khz simply cannot work on the industrial circular connector I used.

(pin5) PH3-BOOT0 is pulled low with 10k resistor on my pcb.

Sorry, I am supporting the WB. I won't be able to accurately answer you. regarding the F7. You should log your question on the F7 group.

Sorry, this is the WB group. I won’t be able to answer you accurately regarding the F7. You should log your post on the F7 group.

OMG, problem solved,

Thanks HSpre.1 for this advice. The flat cable between ST-LINK and the board is only 8 cm long, but I have change the clock speed to 5 Khz. Maybe higher works also but for me it is fine after hours of trouble shooting. :)
