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.

    Regards,

Brilliant, that fixed it! Unchecking POF_ERROR makes it boot from 0x000000 and removes some of the functionality of the RSU in the App-image. This means you can't use the same image for Factory & App , if you want POF_ERROR-checking in the Factory image.

Not a problem for me.

Thanks Nooraini.
