Preparation of files and Hardware Secure Module (HSM) using the source code and the toolkit provided by STMicroelectronics. Three elements are necessary to perform an SSP sequence using Elprotronic Gangflasher-ST:
Signed file with secret data (*.ssp)
Signed TF-A SSP file (tf-a_ssp<custom board>.stm32)
Programming of the OTP using Elprotronic Gangflasher and the files prepared in the first step.
...
Preparation of the keys (private_key.pem, public_key.pem and public_key_hash) using KeyGen Tool STM32MP_KeyGen_CLI
Preparation of Device Tree files (.dts) for the custom board using STM32CubeMX or STM32CubeIDE.
TFA-SSP compilation (tf-a_ssp<custom board>.bin) using Developers Package with SDK and Device Tree files from previous step.
Signing of the TF-A SSP (tf-a_ssp<custom board>.stm32) using STM32MP_SigningTool_CLI
Preparation of a secret data file (*.ssp) using STM32TrustedPackageCreator (SSP tab) or STM32TrustedPackageCreator_CLI (-ssp option)
Programming HSM modules with a limited number of licenses using STM32TrustedPackageCreator (HSM tab) or STM32TrustedPackageCreator_CLI (-hsm option)
