Need help on Remote system upgrade of CYCLONE III..urgent

Hi mitch,

thanks a ton for the reply.

Here you have triggered a reconfiguration from the factory mode to configure the FPGA image present at the flash location reconfig_offset. Assume Once this FPGA image present at reconfig_offset is configured its software application is running. At this point i want a logic to configure back the Factory FPGA image present at the location 0x00000000 into the FPGA.

When the reconfig_offset image is configured we know we will not be in factory mode and as per the altera document we cannot trigger a configuration of a FPGA image in this mode. Hence we cannot trigger a configuration at the offset 0x00000000. Is there any way i can configure back the factory image.

Thanks a lot in advance.
