STM32H503 - crash when attempting to provision password for DA

[Torin]

I'm using a working + tested board with the STM32H503KB; connecting over SWD via an ST-Link board. I'm on MacOS and using version 2.16 of STM32CubeProgrammer.

I am attempting to use the programmer to write a SHA256 password hash to OTP memory, in order to configure debug authentication. Without this, I cannot progress the product state to Provisioning or higher without losing device access. I am finding I am unable to perform this through either the GUI or CLI.

First, I'll describe what happens in the GUI. I successfully connect to my target, enter the Secure Programming section, and click the PROV tab. I enter a password, choose an existing directory for the password file to be saved, and click Start Provisioning. Here is a screenshot just before I click the button.

When I click Start Provisioning, the window instantly closes; no error dialog is shown.

When running the application from the terminal, executing /Applications/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/MacOs/bin/STM32CubeProgrammer , and performing the same operation, the log shows this:

[..............]

When I try to use the CLI instead, I get a similar error. I execute:

/Applications/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/MacOs/bin/STM32_Programmer_CLI -c port=SWD -pwd value=[REDACTED] path=/Users/tcb/stm32h5_da

and get this output:

If any ST folks are reading this; this is blocking the preparation for an important product manufacturing run, so I would really appreciate some help here.

Any suggestions welcome. Thank you.

Edit: I have attached an error log produced by the GUI app during the crash.

Hello,

did you try to follow this wiki article : 

https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_DA_access_on_STM32H503

It explains in 2.3 how to provision password : 

https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_DA_access_on_STM32H503#Provisioning_-_Step_3-_Provisioning_the_password_and_setting_the_final_product_state

@Chloe Meunier ,

Thanks for your reply.

The wiki article does not cover my use case. Our development machines are running macOS, and we do not use IAR Workbench.

Referring to my original post, there is clearly a bug in the macOS version of STM32CubeProgrammer. I would really appreciate it if you could raise this with the relevant team!

Hello,

could you please test with an older version of STM32CubeProgrammer, like v2.13.0 ?

Best Regards

I have a similar problem on windows. Using GUI it stalls on "Password hash Calculation..." and then nothing happens. It doesn't even crash.
Using CLI it outputs the "HASHED : [REDACTED]" but then the command exits AKA nothing happens.

Im providing the log file of CLI attempt vith verbose level 3.

As suggested, I tried with V2.13.0
The CLI password programming was succesfull after which I set the PRODUCT_STATE to provisioned. That resulted in "Error : failed to reconnect after reset !"

After this the uC isnt detectable by STLink in DA discovery or any other way.

Hello,
it seems you are using a NUCLEO-F302R8?

Hi Chloe,

thank you for your reply.

I'm using STM32H503EBY6TR (Rev Y) on a custom hardware board.

Kind regards,

Hello,
To provision the password you can use the commands used in the script provisioning.bat.
This script once user password (hash of the password) created, launches the script password_provisioning.bat, you can try to reproduce this?

Hi,

I did try that script with no luck, just bricks the chip every time.

I have opened a support ticket and will continue there, thank you!

If and when I have the solution I will follow up here to help others with the same problem.
