problem when program is running in IDE

Hi icesword,

What do you have mapped at 0010_0000 ?

I have the same problem. If i try to run the programm ("hello world") then i get this message:

----

Using cable "USB-Blaster [USB-0]", device 1, instance 0x02

at the address 0x0200_0000 is the sram.

If i have after some tries success with the download then i get this message:

---

and no "Hello from Nios II!" output in terminal window.

Before somebody say that i should use a "USB Blaster revision B", i'm using a USB Blaster Rev. B

Hi,

You will need to check what the peripheral/memory device at that failed location you have. Most development boards come with reference designs; are you using a reference design provided by the board manufacturer?

Once I found this error, it was caused by a bad SDRAM configuration, memory write cycles seemed to work OK but verification failed.

You will also need to check your NIOS Eclipse project debug configuration.

Check the pin assignments.

dedicated pins connecting to off-chip components cannot be moved

or check if you are trying to download to ext_flash (u5)

you can write but verify fails due to block corruption

hey if it works then check if your stdout is mapped to jtag ?

in project system library properties

Hi frinds,

1, Check your address assignmrnt, and you could use auto assignment! then build it again

2, I have ever meet a problem, Byte blaster II is not good for debugging, which is always error, But Byte BlasterMV is very good. my experience only for refererce!

Sounds like a problem with the hardware design.

- Check to make sure you have the correct timing for the memory you are targetting.

- Check to make sure you have the proper board layout for the memory that is giving you problems (traces, shorts, solder balls on the pins, etc...)

- If you are using a Nios development board make sure Unused I/O are set as input tristate pins

- Make sure you are meeting timing in your design and have taken offchip timing into consideration

Those are a few things that pop to mind. If that doesn&#39;t get you through the woods post again and hopefully someone will think of a solution for you.

Hello all,

I am re-releasing a custom development board that was running with 5.0(FULL) now with 5.1(Web).

I get the infamous:

Verify failed

Leaving target processor paused

Normally, I would also suspect hardware as a first option. However, I switched PCs and re-ran my 5.0(FULL) and my development board is working fine. So Hardware IS NOT ALWAYS A CULPRIT HERE.

What I did to port 5.0 Full to 5.1(Web)

1. Delete old NiosII Core 5.0 (Licensed) and insert time-limited 5.1 core(Reset my processorrs characteristics : fast, no tightly coupled memory, etc.)

2. Loaded Virgin machine with 5.1(Web) , 5.1(Megacores) and NiosII5.1 eval(time-limited)

3. Had to edit qsf because I had incremental compiles set and Web5.1 does not support.

So now with 5.1 (Web)

-Recompile worked fine.

-Program of device successful

Run SW

-SYSID verification okay

- Get Processor paused message( Verify Failed)

Any thoughts?

Thanks,

-Baycool
