Error (213051): File <filename>.key does not contain key <key>

Description

Due to a known problem in the Quartus® II software version 14.0 and later, you may see this error when using the Convert Programming Files utility or the quartus_cpf command, and the <key> in <keyfile>.key contains upper case letter(s) in the key name.

Resolution

To avoid this error, only use lower case letters in the key name.

This problem is scheduled to be fixed in a future release of the Quartus II software.
