Using DE2 board with Quartus and NIOS IDE Version 8

[Altera_Forum]

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.   Georg

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.

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.
