Hi rt52,

My apologies I mixed up my explanation earlier, the above mentioned workaround was meant for the stratix 10 device, not Max 10. Also. MAX10, it actually has a built-in configuration memory and doesn't support JIC. What I can only suggest for now, try to check the “Enable real-time ISP” option in the programmer GUI. There's a case whereby the customer was able to perform configuration on an encrypted file (not RSU). Though, it is because when you enable this real-time ISP, it is a slow mode and normally user will not have this issue if program without speedmode (real-time ISP enabled) but the programming time is longer.

Regards,

Fakhrul

I do not see how this will help. My issue is not programming an encrypted .pof with jtag, that works just fine without checking that box. Is there anything else to try when downloading an encrypted .rpd file? This device will have jtag disabled when shipped so having an update over jtag is not an option.
