I have the exact same problem with quartus 12.0

but for me it woks fine in quartus 11.0 sp1

there is thread that says :

'For all Avalon-MM masters that use arbiterlock, add burst capabilities to the master and set the burst count according to the duration of arbiter lock required. For example, replace an arbiter-locked transaction of 16 accesses with a burst transaction using a burst count of 16.'

but I don't know how to do this ... :confused:

This issue was fixed in the 12.0 University Program installer. Give that a try.

Have you try it?? because I have, and it shows the same issue.

For me it works in quartus 11.0 sp1 with the 11.0 University Program installer.

With quartus 12.0 and the University program v12.0 this particulary core doesn't work.
