stratix II EP2S60

[Altera_Forum]

I am just starting with FPGA, and i need help if its possible. 

 I have a board "stratix II EP2S60" and I want download the file "nios.sof" via Jtag Uart, but I have an error, I receive the message:  Error: Can't communicate with device. Device will stop functioning when it reaches its non-tethered mode timeout limit.  after compilation, I receive the message: Warning: Using design file cpu_jtag_debug_module.vhd, which is not specified as a design file for the current project, but contains definitions for 2 design units and 1 entities in project + the file generated is "nios_time_limited.sof"??????   Thanks

You don't seem to have a valid Nios/IP Core license available. That means that Quartus creates a file called nios_time_limited.sof instead of nios.sof. When you download it and loose the connection to the device a timer starts to run and after about a specific time the Nios/IP Core will stop working. 

 You often loose connection to the device when downloading Nios software, so you get the message about non-tethered mode.  The warning can be avoided by adding the file cpu_jtag_debug_module.vhd to your project file.

thank you Lokla for your help 

 I think that you are right, I have not the licence for the IPs

problem !!!!! 

I think that is not the licence because i try the tutorial project and it's works !!!!

[Altera_Forum]

even if the file is "time_limited.sof" it would have functions

I didnt say it wouldnt work. It will work for at least an hour before the cores shutdown. If you are having trouble that the design doesnt work, you are facing another problem.

Dear all, 

I am also using stratix II EP2S60  I use Quartus and Nios version 6.0  After finish compiling all, I have a problem with Nios when I download . The error appear as following:  Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Pausing target processor: OK Reading System ID at address 0x021208B8: verified Initializing CPU cache (if present) OK  Downloading 01000020 ( 0%) Downloaded 62KB in 0.9s (68.8KB/s)  Verifying 01000020 ( 0%) Verify failed between address 0x1000020 and 0x100F457 Leaving target processor paused  another thing I don't understand is if I download other programs ( for example: the program in "C:\altera\kits\nios2_60\examples\vhdl\niosII_stratixII_2s60\standard" ) It's ok. But my own program has that trouble.  Please help me. I tried so much but can't figure it out. Thanks alot .  Best regards,
