I am using Arria ii GX FPGA development kit. I have no idea on how to program the flash using the PFL as mentioned in page 22(secondary method) in the reference manual (http://www.altera.com/literature/manual/rm_aiigx_fpga_dev_board.pdf) Flash is 512Mb CFI interface. FYI, I have convert my design from sof to pof. Problem Faced: 1. It can't load the factory default pfl image in the programmer automatically. 2. Chain method and error faced as described in attachment Pls advice on it.
