Hi guys,

For problems with the EPCS controller with Cyclone III (and IV) devices try switching to Quartus 10.1.

I could not get any communication with the EPCS chip on my custom board from the Cyclone III with Quartus 10.0 (SP1) no matter what work-arounds I tried with those dual-purpose pins, the assignments etc.

Being somewhat a sceptic - I ported the design back to Altera tools 7.2 and ran the Altera standard memory test on the EPCS. Worked just fine. So I took faith in one hand and a large cup of tea in the other.... and installed 10.1.

Looks like the folk at Altera have come through with a fix.

Now, there may be other bugs lurking under the skin of 10.1 somewhere - but my board is happily booting from flash; so I'm happy for the moment.
