Nios Problem

[Altera_Forum]

Hello, 

I am runnning a simple hello program using DE2-70. But still getting error mssage as:   Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x064240D0: verified Initializing CPU cache (if present) OK Downloading 02000000 ( 0%) Downloading 02010000 (88%) Downloading 06421020 (99%) Downloaded 73KB in 1.3s (56.1KB/s) Verifying 02000000 ( 0%) Verify failed between address 0x2000000 and 0x200FFFF Leaving target processor paused   can you please guide me?

Hi,it maybe some reasons as list: 

Firstly you should know where is the address(SOPC every component has its address).Mostly errors happen in the memory or sdram. Secondly,you need to exam you PCB board. And then check every component to find if some interface got wrong links. Last,check the Quartus project:to see if the pio setting right or pll phase shift. Above all,your Nios IDE programme must be right!

verify failed could have several possible couses. 

do you have timing violations reported by your timing analyzer ? is this memory location internal memory or external memory ?  if external, and if sdram have you setup thescdram clock phase correctly ? if external, have you checked your pinning and connection ? can you run a very simple design, just nios and internal memory on your target ?

I have then imported .qsf file for pin assignment. But it is still showing the above error.

you have changed the device but keept the footprint ? 

 you should check which pins have no exact pin location assignments if you have the chance to get access to the version with the prious device, open the project, go under menue -> Project -> organize quartus II settings file and exit this project. now your qsf file is sorted. You will find a section labled as # Pin & Location Assignments # ========================== with all the location assignments, you can copy this into you actual qsf and replace the assignsments there you will also find some other sections for the fitter and pin functionality if used like current strength or fast output assignments, you should also copy them.  192 out of 212 means nearly none ;-)

Which one should be imported?

the correct one ;-) 

 did you save a copy of the quartus design (containing the qsf) before changing the device ?  i do not use import features for this (do they exist?)  i still use a text editor and replace the part

i meant, i am not aware of an importt functionality by quartus for such purposes as i do not use /need them. i just open the qsf with a text editor and do my manipulation by hand. as quarts recognizes these changes. 

 so you can open the copy of the working qsf and extract the required lines

Komaljadhav, 

if you are not sure of the correct qsf file, I think you will solve your problem in a faster and safer way by manually reassigning your I/Os: entering 192 constraints is maybe annoying but it is still a 'human' level task. It will actually take less time than trying to compile and test with a few qsf files you are not sure of.   Regards

Thank You. I will do the same. I hope it will work.
