Stm32H563MI OBKey Provisioning failed problem and PRODUCT_STATE

[BRIAN_LAI]

Hi, I just accidentally modified the PRODUCT_STATE to provisioning and not able to recover.

So, I tried to do the OBKey Provisioning and use DA to regression back to Open State.

I've created my OBKey:

However, provisioning always failed.

Is there any other settings need to be turned off for OBKey Provisioning?
Or is there any other way to turn PRODUCT_STATE back to OPEN again?

Hello @BRIAN_LAI ,

with STM32H56x you shouldn't use encryption.

This may be the reason why it fails.

In fact this is strange that encryption is enabled. If you use the files from STM32Cube_FW_H5_V1.2.0\Projects\NUCLEO-H563ZI\ROT_Provisioning\DA\Config\DA_ConfigWithPassword.xml you will see that it is disabled.

Another way to go is to use the default password provided in STM32CubeProgrammer here: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\DA_Default_Config\STM32H5\NonCrypto\DA_Config_Password.obk

You can try provision this OBK and then use C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\DA_Default_Config\STM32H5\password.bin to re-open

Best regards
