G.4
STM32 and firmware image provisioning
To provision the STM32 with the pairing keys and insert the certificates in the firmware
image headers, the prepare image tool concept of the X-CUBE-SBSFU Expansion Package
is used (refer to
Appendix E Firmware image preparation tool
for more details):
•
IDE pre-build script is used to insert pairing keys inside the SBSFU code
•
IDE post-build script is used to insert certificated inside the firmware image header

G.5 STSAFE-A100
ordering
To use the STSAFE-A100 in the context of the SBSFU application example, the STSAFE-
A100 must be personalized at STMicroelectronics manufacturing stage with some specific
data (such as private keys for instance) corresponding to a profile called "SPL2".
The sales reference for ordering the STSAFE-A100 device is STSAFA100S8SPL02.
