Arria 10 Reconfiguration

Hello,

I am working with an Arria 10 (10AS048) and using an external FPGA to manage configuration from a flash memory. 

When working with a non encrypted image, i am able to configure, then reconfigure, without issue. 

When i try to do the same thing with an encrypted image i have success on the initial configuration. Once i try to reconfigure I never get config_done. The A10 never pulls nStatus low to indicate a CRC error. When encryption is used is there something in the A10 that is stopping reconfiguration?

Thanks
