'Leaving target processor paused'

--- Quote Start ---

When i found this problems with my own designs would be, all the time, that i have surpased the fmax acceptable for the system/FPGA i was running on

Maybe with a time constraining you will fix this.

What i have found to work is (obviously) to low the clock speed to slower values.

(For example, NIOS II running over 110 MHz in a 7 speed grade Cyclone II would fail to verify; after making the clock 100MHz, it would run find)

Thanks for your reply!

Your message is very helpful.

But I think my problem is about the nios2eds for Linux version.

Because I downloaded the nios2 sys using Windows version, and it ran well.But I downloaded the same project using the Linux version, it couldn't run well.

Maybe there were some error when I installed the Linux version, and some .so file couldn't be found. And I use the command 'sudo ln -sf ' to link the .so file.But I thought there were some other errors.

Maybe the nois2eds for Linux version does not work well on Ubuntu, and maybe it will work well on the RedHat.

I had change to the Windows xp.

After accomplishing my project which my teacher assigned to me, I will try to solve it.

And thanks to you again.You message is really helpful.

If you installed the nios2eds on Ubuntu, please share your installation experience to me!

Ubuntu and debian have linked /bin/sh to a reduced version of bash (dash), and the altera tools expect to have a bash complete implementation in /bin/sh

Maybe changing this will make the tools behave well again

Thanks for your helpful reply!

I used a command like 'sudo ln -sf /bin/bash /bin/sh' to change to use the bash.

And I tried again.

Some errors were solved.

But there were some errors yet!

The error messages were below

Using cable "USB-Blaster [USB 2-1.1]", device 1, instance 0x00

Pausing target processor: OK

Initializing CPU cache (if present)

OK

Downloading 00008000 ( 0%)

Downloaded 15KB in 0.1s

Verifying 00008000 ( 0%)

Verify failed between address 0x8000 and 0xBBB3

Leaving target processor paused

This was a very sample program.

I used the template 'hello world' in the nios2-ide.

In the sopc builder, I used the on-chip memory, and auto-assign base address.

The address 0x8000 and 0xBBB3 is on-chip memory.

But why verify failed?
