STM32H7S78-DK: Reset PRODUCT_STATE to OPEN

[rk_iot]

Hello,

i've set the PRODUCT_STATE of my STM32H7S78-DK in the STM32CubeProgrammer from Open (39) to Revisioning (17):

When trying to reset the state to Open again I get following error:

Is there a way to reset to the product state to Open again? I've read that there should be the possibility to do a full regression in PRODUCT_STATE Provisioning but how do I do that?

 

Thank you an best regards,

rk_iot

Hello @rk_iot;

 

I recommend you to follow the steps shared in 4_debug_authentication to reopen the device.

For more information about the different product state, you can look at RM0477 section 4.9 Product life cycle.

Thank you.
