ID:11986 Volatile key programming mode is selected. However, when CvP and non-volatile design security features are enabled, file conversion is not allowed for internal active serial clock source that is greater than 12.5MHz

CAUSE: You attempted to convert a file with the Configuration via Protocol (CvP) and volatile design security feature enabled for Stratix V, Arria V, or Cyclone V device. Ignore this message if the non-volatile mode is not used.

ACTION: Use an active serial clock source with 12.5MHz or less when converting a device file with the CvP and design security feature enabled.
