Hi,


If you try to configure an encrypted MAX 10 FPGA with an unencrypted programming file, the configuration process will fail because the device requires the correct encryption key to decrypt and apply the configuration data.


If you are using encrypted pof, then you will need to always include .ekp to program with POF as the erase function will always erase the key and bitstream.
