Provisioning OptionByte Key data with the CubeProgrammer API

[MichaelWaites]

Hi,

I'm looking into creating a custom tool to provision our STM32H533 boards which will allow a non-trusted 3rd party to flash the firmware, configure the Option Bytes and program secret keys into the OptionByte Key storage areas.

I cannot see any way to program the OB Key data via the API.  Is it possible?

For reference, the CLI parameter would be -sdp secret_key_file.obk

Thanks in advance.

Hello @MichaelWaites ,

Apologies for the delayed response.

Unfortunately, at this time, the provisioning of OB Key data is not supported by the STM32CubeProgrammer API.

I have forwarded your request to the concerned team.

Internal ticket number: 208305 (This is an internal tracking number and is not accessible or usable by customers)

I will keep you updated on any progress regarding this feature.

Maryem.

Hi Maryem,

Thanks for responding and raising a ticket.  I've got my fingers crossed that the internal team considers this a worthwhile addition!

Best regards,

Michael
