STM32H573VI: Bricked in "Provisioning" product-state while tring to applicate DA on device

[MattiaB]

Good morning everyone,
I need to apply the "Closed" product state to my device using the STM32H573VI.
I don't need TrustZone enabled and want to use a password for debug authentication.

I wanted to perform the operation via "code" using the HALs, but once I set the state to "Provisioning(0x17)" from "Open(0xED)," my firmware won't boot, and I can't even provision the *.obk file using the STM32CubeProgrammer.

bool ProductState::set(states newState)
{    
    FLASH_OBProgramInitTypeDef flashOptionBytes= {0};
    HAL_StatusTypeDef ret {HAL_ERROR};
    
    if(newState == states::Unknown) {
        Log::msg("Invalid product state\n");
        return false;
    }
    
    Log::msg("Setting product state to %s ...\n", toString(newState).c_str());

    HAL_FLASH_Unlock();
    HAL_FLASH_OB_Unlock();

    flashOptionBytes.OptionType = OPTIONBYTE_PROD_STATE;
    flashOptionBytes.ProductState = (static_cast<uint32_t>(newState) << FLASH_OPTSR_PRODUCT_STATE_Pos);

    Log::msg("Program state ...\n");
    ret = HAL_FLASHEx_OBProgram(&flashOptionBytes);
    if (ret == HAL_OK)
    {
        Log::msg("OB Launch ...\n");

        ret = HAL_FLASH_OB_Launch();
        if (ret != HAL_OK)
        {
          Log::msg("Error while execution OB_Launch : %d\n", ret);
        }
    }
    else {
        Log::msg("Error while setting OB Bank1 config state %s : %d\n", toString(newState).c_str(), ret);
    }
    
    HAL_FLASH_OB_Lock();
    HAL_FLASH_Lock();
    
    return (ret == HAL_OK) ? true : false; 
}

I then tried to do the entire process using the STM32CubeProgrammer on another board.
I'we followed the video: STM32H5:Product state 
- I flashed my application (a simple blinking LED) with IAR
- I changed the product state from "Open" to "Provisioning"

But no luck. Once the Provisioning state is set, I can't provide the *.obk file using the PROV dropdown.

Product state is 0x17 as correctly expected:

So both behaviours are equals using directly HALs drivers or STM32CubeProgrammer.
Can anyone please help me figure out what I'm doing wrong?
Thanks in advance for your help.

Hello @MattiaB ,

please connect in hotplug mode. You will be able to provision the board.

Then please check you can do a regression in this state before going further.

This will validate that the DA obk you provided is correct.

By the way, I would recommend having a look to the wiki How-to to get started with a new feature

Best regards

Jocelyn

Hi @Jocelyn RICARD,

Also in hotplug mode I'm not able to provide the OBKey:

The STM32CubeProgrammer is the last downloadable:
