Cyclone V - CRC_ERROR Automatic Reconfiguration

Hi, We have developed a board with a Cyclone V FPGA and we want to implement automatic reconfiguration in case a CRC_ERROR is detected in user mode. For example, if a SEU alters FPGA configuration ...

Hi,


In the datasheet, it mention "When enabled, the user mode error detection process activates automatically when the FPGA enters user

mode. The process continues to run until the device is reset even when an error is detected in the current frame."


Meaning that when CRC error is detected, you will need to reset the device by setting the nConfig to low to reconfigure it again. the nConfig will not go low by itself if the CRC error is detected.
