Issue with Altera MAX10 FPGA Development Kit and "MAX10 JTAG Secure Unlock" Example

Hi,

Have you checked that it is being loaded with an encrypted configuration file? Tamper protection mode prevents the FPGA from being loaded with an unencrypted configuration file. When you enable this mode, the FPGA can only be loaded with a configuration that has been encrypted with your key. Unencrypted configurations and configurations encrypted with the wrong key result in a configuration failure.

Also, before programming the non-volatile key into the devices, ensure that you can successfully configure the FPGA with an unencrypted configuration file.
