Remote Update for Cyclone Reset Question and Application Image Question

Hi Brian, 1. What do you mean by “remote update module must be reset one time”? Do you mean Reconfiguration? Basically you need to have Reset State (condition: nConfig is low) after power up the device. Then, you need to have one State to toggle nConfig from ‘0’ to ‘1’and nStatus from ‘0’ to ‘1’. Once your nStatus is high, you are in Configuration-Mode. Then, you can start the status bit/read address from flash to boot up the FPGA device with Factory or Application Image. Thus, if you reconfiguration the FPGA (nconfig is toggle to ‘0’), regardless you boot up from Factory image or Application Image, you will go to Reset State again. 2. When your application image code has a logic error, the Active Serial (AS) Controller will load the same application image for 3 times before reverting back to factory image. You also have an optional feature to choose User Watchdog Timer option that can detect the functional errors in an application configuration. Kindly refer to the attachment picture for more understanding. Thanks
