Occasional ContributorCan I write a ".rpd" file that only contains the application image to an EPCQ device in RSU?
Hello experts,
I want to write a ".rpd" file that only contains the application image to an EPCQ device through "ASMI parallel IP" for remote upgrading the system (RSU).
The factory image has been loaded to the EPCQ with a boot_address = 0h (10LP) through the standard programming method of AS scheme (quartus generate .jic file -> programmer -> sfl -> epcq).
I have generated a .rpd file that only contains the application image in the "convert the programming file" tool. Now I need to write this image to the EPCQ with a start address = 400000h, which is half of the memory.
But I'm not familiar with this file type, so I want to make sure that can this plan work? Will covering the second half memory damage the factory image (if the factory is only in the first half memory)?
Thank you very much!
Hi,
There shouldn't be any issue on writing the 2nd half of the flash if it is not overwriting the factory image (if you confirm that it is able to fit within the 1st half of the flash).
You can refer to design example from https://www.intel.com/content/dam/altera-www/global/en_US/uploads/4/4f/Remote_system_upgrade_c10lp_quick_start_guide.pdf
