    Hi JHono,

    In your application image design, did you set any write_param on the boot address that point to 0x100000? Please remove any write_param operation in the application image design. If you refer to Table 17: Cyclone IV Devices Remote Update Operation from the Remote Update user guide shows that you can only perform read_param operation in application image:

    Also, please uncheck the POR_ERROR function in the application image design. This POF_ERROR function is only needed in the factory image to detect any invalid application image before reconfiguration process start.
