APEX Nios Dev kit

Kerri, Thank u for tracking my topic, I tell more about the problems:

1.

The Dev Board

I use Nios Embedded Processor Development Board

http://www.altera.com/products/devkits/alt...a/kit-nios.html (http://www.altera.com/products/devkits/altera/kit-nios.html)

http://www.altera.com/literature/ds/ds_nio...pex_20k200e.pdf (http://www.altera.com/literature/ds/ds_nios_board_apex_20k200e.pdf)

Notice:

P16 Table 2. Factory-default APEX device configuration

and "Altera recommends that users avoid overwriting the factory configuration data."

Maybe someone in my lab overwrote the factory configuration data.

2.

Step by step

I step by step my first Nios 32 project following "Nios Tutorial"

http://www.altera.com/literature/tt/tt_nio...pex_20k200e.pdf (http://www.altera.com/literature/tt/tt_nios_hw_apex_20k200e.pdf)

At last when I download the project to Apex, It didn't work. But the project worked properly

in another same dev board.(We have 5 boards in My lab)

3.

Test Apex

To test whether Apex is damagered or not, I download a project, which simply input from SW1

and ouput to LED1 and LED2 without any Nios, and it worked finely !

In my opinion, the hardware including devices and connecting wires do not damagered, but the data in flash is not correct. So I wonder how to reload the factory flash data to Flash device. Do you agree with me? What's your opinion,please?
