Secure Secret Provisioning SSP is the final step in production programming and is designed to protect the MPU from unwanted access to registers or running unauthorized software. The SSP procedure is to write secret data and keys to the OTP using files properly prepared by the OEM. Elprotronic ST-Gangflasher software offers the possibility to write OTP according to the SSP procedure developed by STMicroelectronics on many MPUs simultaneously (Gang programming) which is beneficial for the production of a large number of devices.
Instructions
The procedure consists of two main steps:
Preparation of files using the source code and the toolkit provided by ST.
Programming of the OTP using Elprotronic Gangflasher and the files prepared in the first step.
