Why does my ARRIA II GX Nios II design fail to boot up in V13.1 and V14.0

Description

Due to a problem in the Quartus® II software versions 13.1 and 14.0,  Nios® II designs targeting ARRIA II GX devices using the EPCS IP may not boot correctly.

Resolution

To work around this problem follow the steps below:

1. Open /ip/altera/sopc_builder_ip/altera_avalon_epcs_flash_controller/em_epcs_qsys.pm file in a text editor
2. Add the ARRIAIIGX device into the condition check logic at line 704
   
   • Before: ( eq "CYCLONEIVE"))
   • After: ( eq "CYCLONEIVE") || ( eq "ARRIAIIGX"))

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