Nios II Problem!

Hi Sir/Madam,

Actually I am finding one problem in my design that after fusing the .sof files when I run software the processor get paused.

This problem comes most of the time when I enable the signal tap. When the signal tap is disabled the software runs properly. what comes in console window of Nios II is as given below.

I will be thankful for your kind sugestion.

Have a nice day!

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Processor is already paused

Reading System ID at address 0x00C10C60: verified

Initializing CPU cache (if present)

OK

Downloading 00800020 ( 0%)

Downloaded 63KB in 0.7s (90.0KB/s)

Verifying 00800020 ( 0%)

    It can have all sort of reasons, most probably a faulty memory interface. Search for this error message in the forum for suggestions.

    I restarted Nios, Quartus, theUP3 kit and then the problem was no more....probably this is not the exact solution, but certainly one option to consider....

    (though this is an year old post, i am replying here so that someone else who is looking for solution can read this...)
