Locked out from DA on STM32H5

[coso2]

Hi, I am trying to implement DA on an stm32H563, I have created the .obk file, and was selected in the Stm32Programmer. I have changed the product_state to provisioning and I got the message "Do you want to use the default?"

I clicked YES and I got the default DA, located in ..\STM32CubeProgrammer\bin\DA_Default_Config\STM32H5

I was able to perform a full regression and then I tried again to flash and secure the chip, and this time I did choose "NO" to the default. Now I have tried my DA password and the default and none of them works. Also, I did at first tried to provision the mcu with my obk file, but was complaining about the OB not in provisioning. So after the provisioning I got locked out.

Can the board be saved in any way or I have just bricked an mcu?

I am using the STM32H563 Nucleo

Thanks

Ale

Hello @coso2 ,

If you are still in provisioning product state just launch the regression.bat located in STM32Cube_FW_H5_V1.5.1\Projects\NUCLEO-H563ZI\ROT_Provisioning\DA\

You should recover your board.

Best regards

Hi, I was able to connect via serial and complete the process, providing my .obk file and then performing a full regression with the password file. In provisioning state I was not able to connect via STLINK. Now the board is working. Thanks
