Honored ContributorMy projects don't run.
Hello to everybody.
I have DE1 (with EP2C20F484C7 FPGA device and EPCS4 serial configuration device). I run Quartus II v.9.1 web in a Vista computer. I have set up USB Blaster driver software in my computer. My projects run OK in JTAG programming (sof files) The same projects don't run when in SA programming mode (pof files). However I can download and run OK the sample projects (DE1_Default.pof, DE1_USB_API.pof ...) Can enyone help me?21 Replies
Altera_ForumHi,
this sounds perhaps to be related to the problem with compressed programming files generated with v9.1. You should check for the "Generate compressed bitstreams" option in Settings -> Device -> Device and Pin Options -> Configuration to be deselected. Hope that helps Carlhermann- Altera_Forum
Quartus 9.1 seems to have a bug with generating EPCS related files.
If you take the fpga image generated by quartus 9.1 and your application elf and generate epcs files with quartus 9.0 then everything is alright, same files used with quartus 9.1 won't run. see this thread epcs booting problem (http://www.alteraforum.com/forum/showthread.php?t=19496) - Altera_Forum
Thanks a lot. The information you provided was really helpfull.

Although failure of compressed EPCS configuration in Quartus 9.1 files is treated as a fact in Altera Forum, it's not listed with Quartus known issues. I wonder, if any forum member who oberved the problem ever filed a support request?

I got notice, that Altera has recognized this, and that this problem is on their list of things to be fixed in either next SP or next version of QuartusII (whatever comes first...).

That's good. But it should be listed in knowledge base, I think. Or did I miss the entry?
It's a severe bug in my opinion, because you won't think of a software error but suspect your hardware, possibly replace parts, damage your prototype during desolder and things like this. - Altera_Forum
Well, don't ask me...
I really searched around (and around and ...) until I found this problem not being related to my hardware... I don't know why it's not listed anywhere - at least here in the forum the problem of no longer working designs with v9.1 has been reported many times now... Sincerely, Carlhermann - Altera_Forum
@ FvM
i have an open service request since november 11 and still hoping to give : "Quartus II 9.1 Patch 0.63 Patch SPR#: 330296" a try. But still haven't get any update so far. I agree with you, this is a bug that should be official mentioned and or stated to prevent users from damaging their targets due to impossible "bug" removements that are not more than a suicide mission for the target and mostly lead to no solution. - Altera_Forum
just received the patch from MySuport and it works now as expected.
that patch seems to solve this issue. (and hopefully does not introduce other issues) - Altera_Forum
Where can i find this Patch?
