Error in NIOS Dev Kit, Reference Manual ?

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,

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.

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