Cyclone V flash upgrade problem

[Altera_Forum]

Hi,  

 I am new to this upgrade thing for the FPGA. I am using a cyclone V fpga now and i am trying to do a flash upgrade of it when i require. I read some docs and have created the altera_remote_update megafunction for the upgrade functionality. On the software side I am using Atmel to configure the registers. I am now confused how to find out the pins on the megafunction side for connecting it to the atmel so that I can do a upgrade from the atmel to the fpga.  Can anyone guide me through to what I should do.  Thanks, Sid

What configuration scheme are you using? Is the Atmel part you mention a micro that configures the FPGA or a memory part that the FPGA configures from? 

 If the former then you need to solve this in the micro.  If it's a memory part then read through the 'remote system upgrades (https://documentation.altera.com/#/00005773-aa$nt00073227)' section of the Cyclone V Device Handbook. The altera_remote_update megafunction comes in handy here. Look at the "altera remote update ip core user guide (https://www.altera.com/en_us/pdfs/literature/ug/ug_altremote.pdf)" and, in particular, the design examples.  Cheers, Alex
