Updating EPCS

Is it possible to update the software code stored in Alteras EPCS flash? I know these devices are basically SPI flash, but the Altera device has dedicated pins connecting it. Thanks in advance,...

You have access to the EPCS controller via the HAL "alt_flash" hardware abstraction. The only thing you need to look out for is that, by default, the end of the hardware image and the beginning of the software image fall in the same block....so you would need to do a read-modify-write cycle on that block.
