SiLabs
Silicon Labs Series 2 wireless SoCs put a Cortex-M33 with TrustZone next to a radio and a dedicated security subsystem. The EFR32MG2x family targets connected products that have to prove their firmware is authentic and stays that way through years of field updates.
Our course covers that security stack end to end: TrustZone partitioning, the Security Attribution Unit, secure boot with the RTSL root of trust, Secure Vault key storage, Gecko Bootloader configuration, secure debug lockdown and OTA update with anti-rollback.
The detail matters here because the chain breaks at its weakest link: fuse and OTP programming that cannot be undone, key provisioning during manufacturing, the anti-rollback counters that stop a downgrade attack, and debug lockdown that has to leave a way to diagnose returns. The course covers each step in order.
