Parallel Flash Loader - Parallel Flash Loader We are using a MAX10 to configure an Arria V, serving as the bridge between Arria V and the 4 memory devices. I have noticed the fpga_nconfig is not being pulled low to initiate configuration but the Arria V is still being configured. The device is configured at power up, is there something in the IP that allows configuration to take place at power up without fpga_nconfig? Attached is a scope capture of fpga_nstatus (bottom trace) and fpga_nconfig (top trace) at power on. The version of altparallel_flash_loader is WM1.0. Thanks. Replies: Re: Parallel Flash Loader Yes, you are right. Replies: Re: Parallel Flash Loader YuanLi_S, Yes I am referring to the Arria V nConfig pin. I just want to confirm correct operation as the nConfig pin is never "released" high by the PFL engine, rather it rises with the power supply and stays high. I just want to confirm that this is correct, reference my attachment in my original post. Thanks, Brian Replies: Re: Parallel Flash Loader Hi Brian, Are you referring to Arria V's nCONFIG pin right? As per the user guide, it needs to be pulled high for configuration. https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/arria-v/av_5v2.pdf *Page 280) Thank You
