Remote re-configure a Cyclone IV in Application-mode?

Is there a way to set the remote_update-core back to Factory-mode or re-configure to another image once it is in Application mode - i.e. without a power-cycle? Both my Factory & App-images have acces...

    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.

Hi Jhono,

You can just trigger the reconfig input from the RSU IP if you want to fall back from App images into Factory image. However there is no direct reconfiguration option between App image to another App image. Before you can reload a App image, you always need all back info Factory image and set all the parameter for the App image then trigger the reconfig input from RSU IP. You can refer to Figure 10: Remote Configuration Mode from the Altera Remote Update IP Core User Guide here:
