Is there an issue after hard memory controller design without specific INI file being programmed on Arria V ES device ? - Is there an issue after hard memory controller design without specific INI file being programmed on Arria V ES device ? Description Design using Arria V ES with hard memory controller compiles fine in quartus and you can program the board successfully. However the design will have problem to work properly on board. Resolution Create a quartus.ini file that include the below settings in the INI file. This quartus.ini file should be save in the quartus project directory. PGM_CONFIG_IO_A5 = ON PGM_A5ES_IOCSR_RECONFIG=ON Custom Fields values: ['novalue'] Troubleshooting novalue False ['novalue'] ['FPGA Dev Tools Quartus II Software'] novalue 12.1 ['Arria® V GT FPGA', 'Arria® V GX FPGA'] ['novalue'] ['novalue'] ['novalue']
