problem with quartus II

[Altera_Forum]

Hi! 

I use the Quartus II 6.1 in my work when implanting my program on the FPGA (Altera Startix), in the NIOS II in the software part of my project. in the console, this problem percists: Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Pausing target processor: OK Reading System ID at address 0x00810828: does not match  ID value does not match: read 0xE47B14E5; expected 0xD0E90EBE  Timestamp value does not match: image on board is older than expected  Read timestamp 20:51:20 2008/03/12; expected 9:59:00 2008/03/13 The software you are downloading may not run on the system which is currently configured into the device. Please download the correct SOF or recompile. Restarting target processor

This would be better answered on the Nios Forum website, where there's a lot of information on this topic. 

 The answer is that every time you change your SOPC Builder system (even inadvertently), you need to re-compile in Quartus II. The tools are trying to prevent you from using software with a non-matching hardware design. It's not a bug, but rather a very useful feature...  You _can_ override this functionality (it's documented in the Nios II IDE help), but I'd advise against it.  Cheers,  - uraslacker
