Re: EPCQ replacing EPCS128

Altera_Forum · ‎05-17-2018

I use a Arria V with an EPCS128. When I replaced it with an (Altera) EPCQ128A, it programs/verifies fine (.jic using 13.1 programmer) but the Arria won't start (flash won't load?) when I power-cycle. I was hoping to find a drop-in replacement that would not require a change to the code. AN-822 seems to imply that no change should be needed. Would another-version stand-alone programmer help? Thanks.

Hi,

Hope your old .sof file is loading.

What is the status of CONF_DONE?

1. Have you followed IP Core Regeneration Guideline and Programming File Regeneration Guideline from an822?

2. Have you tried the new program? To check if Flash loads after a power cycle.

If not working monitor the nSTATUS and CONF_DONE.

if it is low, it may be a power issue.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Anand,

Thank you for your reply. Before I begin following the steps, I just wanted you to know I have been following tomatoma on a very similar issue. In a May18 3:10pm post, he was able to make his board functional by adding capacitance to the data lines. And he mentioned a roadblock with .pof vs. .sof vs. jic when following an822. I'll keep you posted.

I am using Cyclone V with EPCQ128A and had to recompile with QuartusII 18.0 after selecting EPCQ128A as configuration device. Now it works.
