Signed CMC firmware image

The CMC firmware includes a signature. The CMC firmware performs a signature verification step to ensure the authenticity of the

uploaded firmware. The firmware update process is successful only if CMC authenticates the firmware image to be a valid image

from the service provider and has not been altered. The firmware update process is stopped if CMC cannot verify the signature of

the uploaded firmware image. A warning event is then logged and an appropriate error message is displayed. The firmware update

includes upgrade and downgrade.

Downloading CMC firmware
