Issue with Remote Update State Machine

While looking for sample designs invoking the RSU via a state machine, I came across an older intel/altera design. The code is designed to repeatedly ping-pong between the factory image and the appli...

    I believe I was able to solve the problem, the addressing I was using for my Serial interface was incorrect and setting my pointer to a much lower location than intended. When the sector erase was executed I believe it was over writing a portion of the data that was used to hold the Factory image.

To add new information gained during debugging, the issue of not returning to the factory image, seems to occur when my GSFI module is enabled in the FPGA code. If this module is not enabled, the system will return to the factory image. I do not have the GSFI state machine running when the RSU state machine is running (for obvious reason), but is there an underlying issue between the two modules? Does the flash used to house the image data need to be in a protected state for the RSU to work?
