Hi
I'm using Cyclone Development Board. I think that there is an errror in "Reference Manual" for that board. On figure 1-6 (page 1-13) pinout for connection betwen Cyclone and expansion connector J12 is not correct. I'm using MNL-N2DEVLBDCYC-1.1 manual. In my opinion, it should be: 1- GND 3- V20 5- J19 7- H14 9- J17 11-K15 13-V18 2- +5V 4- J15 6- J20 8- J14 10-J18 12-W18 14-V19 I didn't find any aswer on Altera's web site. Could someone check it ??? Cheers MichalLink Copied

Hey Michal;
Your pinouts are almost correct with just one change pin 3 should be U20 not V20 so the correct pinout is: 1- GND 3- U20 5- J19 7- H14 9- J17 11-K15 13-V18 2- +5V 4- J15 6- J20 8- J14 10-J18 12-W18 14-V19 I am not sure how this got by us for so long but thanks for bringing it to my attention. Since that one is wrong I started checking the figure 1-5 and it looks wrong too. I will post once I have worked out the pinout for this one as well. Thanks,- Mark as New

The last release of the Cyclone board manual somehow included incorrect pinout information for the PROTO1 header. We just identified the issue and will have a corrected version posted to the web ASAP. Note that this is not just an issue with J12. J11, J12, and J13 are all affected. I believe the PROTO2 header pinouts are unaffected, and the published pins are correct. You can use PROTO2 to get your work done. I will update this thread when the updated document hits the web. Thanks for pointing out this issue with Altera documentation. Matthew- Mark as New

The Nios Development Board, Cyclone Edition Reference Manual is now updated on the Altera web site.
