Using DE2 board with Quartus and NIOS IDE Version 8

Hello, 

 

I've installed Quartus Version 8 and NIOS IDE Version 8 after using Version 7 for some time. With version 7, there was no problem in using the DE2 board with NIOS IDE - everything worked fine. But since I'm using the new versions, nothings runs. Even the simple examples don't work at all.  

 

My first tries were to create a new project, using the system provided with the DE2 board. That didn't work: when I started my program, it crashed with a malloc-fault. It seems that the new project needed to much memory. 

 

Then I tried to import my old projects, naturally with the old system description which worked fine. Then, I ran into a problem that the projects new generated did not build correctly. 

 

I read in the FAQ that there is now system configuration "currently" available for DE2 boards, and that one should build the system with SOPC generator. I ask myself whether that's the only possible solution - it is erroneous since one has to change hardware models by hand in order to reuse the pin assignment file for the DE2. Or do I have overlooked something? 

 

I would be glad if there is some helpful guy who could give me some hints how to proceed.

Did you try re-generating (and compiling) the SOPC system and then compiling and using your old projects? Simply importing old projects in the new version without recompiling the SOPC system will not work.

No. I opened the system with SOPC builder version 8 and got a lot of messages that system parts were automatically replaced. A Generate was possible. However, I did not compile the generated system since I assumed that the pin assignments were lost and it would be a tedious and error-prone work to reassign all. I simply hoped that the HAL provided with NIOS IDE version 8 would work with the hardware generated with version 7.2.  

Now, with your help, I know that I have the choice either to use the old version (7.2) or to recreate the hardware including assignment of pins.
