Hello @Ra.1​ and welcome to the Community :)

I recommend you to update the STM32CubeProgrammer and use the latest release V2.8.0 which contains enhancement as support of FUS version display for the STM32WBxx microcontrollers.

Please keep me informed about your update.

Hello Imen,

thank you so much for your quick response

As per your suggestion i updated the STM32CubeProgrammer and run it in cmd prompt so get same error..!!

even in software it shows

fus state: fus_idle

fus status : fus_no_error

fus version : v0.0.0.0

Did you try "connect under reset"?

[Ra.1]

yes...like by keep pressing reset button after connecting usb need to release the button right..??

i tried like that

[Ra.1]

here board is connecting proprly its detecting in STM32CubeProgrammer tool and cubeIDE so i can upload the example program also..so no connection issue

the problem is not possible to delete the firmware

[Ra.1]

Hi imen,

still no response....!!!

i think its waste community compared to Devzone(nordic) or E2E(TI)

[Ra.1]

Any way we planned to change the controller for our project Due to your poor support

[Imen.D]

Hello @Ra.1​ 

I apologize for the delay I sometimes take to answer , as I'm busy this period.

I will escalate this issue internally for analyze.

Hi @Houda GHABRI​ , @Remi QUINTIN​ 

Can you please help on this post ? What can be the root cause of such issue.

Thanks

Imen

Could you download all the option bytes?

How old is your Nucleo board?
