Option Byte Programming failed

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:

Did you try with the CubeProgrammer tool alone? What is the version used? 2.6 or 2.7?

The option bytes nBOOT0 annd nBOOT1 should be set to 1.

When the nSWBOOT option byte is 0, the nBOOT0 is taken into consideration. If it is set to 0, then you have to set the PH3/BOOT0 pin to 1 as this pin is take into consideration in that case.

LucHardware · ‎2021-05-31

The CubeProgrammer is 2.6.0.

I put nBoot0 to 1, there is no nBoot1 on STM32F767BI

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. :)
