2.1.1.2. Secure Device Manager May Disable Physically Unclonable Function

Description

When firmware co-signing is enabled, the Secure Device Manager (SDM) may disable the Physically Unclonable Function (PUF) access in the following situation:
  • An explicit key cancellation ID of 0 is assigned to any key in the signature chain which is used to co-sign firmware.

Workaround

For PUF access, you can use any other explicit key cancellation IDs (non-zero) in a signature chain that is used to co-sign firmware.
