DE0 Nano - Problem using the provided examples

Hi, 

 

i just received my DE0 Nano board and I've been trying the examples in the system CD. 

I've downloaded and installed Quartus 11.0sp1 + Nios II/Nios II GCC4 Toolchain. 

 

Every example works fine, except the myfirst_niosii example. 

When I execute the batch file, it programs the .sof file into the FPGA, but it is unable to to start the test_bashrc. 

Excerpt of test.bat: 

" "%QUARTUS_ROOTDIR%\bin\cygwin\bin\bash.exe" --rcfile ".\test_bashrc" " 

 

After the .sof file is programmed, it gives an error saying that it is unable to find the nios2-terminal and the nios2-download commands. 

 

From what I can understand these commands are called so that the hello_world_0.elf file is downloaded and run. 

 

Anybody can help me shed some light on this? 

 

Thanks in advance

Check your enviroment variables and add quartus bin to it

I am having the same problem - even with Quartus bin directory added (and confirmed) to the path. 

 

Its very frustrating for the demos to not work. 

Any help would be appreciated. 

 

Host is Win7 32 bit 

added path using controlpanel->system->advanced->environmental variable->edited path by adding ;C:\altera\11.0sp1\quartus\bin\ 

run cmd to open window 

confirmed path environmental var now points to quartus bin 

cd to DE0_Nano_SOPC_DEMO\demo_batch 

run test.bat 

ends with errors of nios2-download and nios2-terminal not found 

dumped to [NiosII EDS]$ prompt

Perhaps this is the issue. Rather than using a windows console, try using the Cygwin bash shell that comes with the NIOS tools (it'll be called something like NIOS II command shell).

Is the console not the best location to run a distributed demonstration batch file? Such as... 

DE0-nano-1.0.5\Demonstration\DE0_Nano_SOPC_DEMO\demo_batch\test.bat 

 

 

i found nios2-download and nios2-terminal in c:\altera\11.0sp1\nios2eds\bin and added it to path environmental variable. It now gets further along, but with different error messages.... 

 

cygdrive/c/altera/11.0sp1/nios2eds/bin/nios2-download: line 596: nios2-elf-objcopy: command not found 

DE0_Nano.elf.srec: Unable to open input file 

rm: cannot remove 'DE0_Nano.elf.srec': No such file or directory 

nios2-terminal: connected to hardware target using JTAG UART on cable 

nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) 

 

 

Searched and found nios2-elf-objcopy.exe 

added c:\altera\11.0sp1\nios2eds\bin\gnu\h-i686-mingw32\bin 

to path, re-opened cmd console, confirmed path, and ran test.bat 

 

Now it seems like it is working. 

 

At some point I will learn more about Nios terminal, for now just want to make sure all the demos are running as a stable base to start with. 

 

Sure wish at least the demos would work straight out of the box. 

 

 

 

 

 

test_bashrc contains the following:

test_bashrc contains bash scripting syntax, while test.bat contains windows shell syntax. 

 

You commented that you started from a windows cmd shell, and got dumped to a [NiosII EDS]$ prompt - which is the Cygwin prompt - so I was suggesting to start from the Cygwin prompt and see if that helped.

Hi, 

 

I also defined every environment variable related to Quartus. That one included. 

But shouldn't all the variables be defined by the setup upon installation????? 

 

Anyway, the first time I installed the Eclipse allowed me to start a new Nios2 C project, BSP project, everything. After some uninstalling and installing of Quartus (always the same version) the options to start Nios2 related project do not appear. Something is very weird with this..... 

 

Anyway, I removed everything Quartus related from the environment variables and the registry. I'm now on my fourth attempt of installing everything. 

 

I just wanna make sure I can compile and execute .elf files for the Nios2 processor at this point. Every other demonstration works just fine. 

 

 

rogerjennings: 

"@ set SOPC_BUILDER_PATH_71=%SOPC_KIT_NIOS2%+%SOPC_BUILDE R_PATH_71%" 

Could the space in "...BUILDE R_PATH..." have anything to do with what we are experiencing?

"You commented that you started from a windows cmd shell, and got dumped to a [NiosII EDS]$ prompt - which is the Cygwin prompt - so I was suggesting to start from the Cygwin prompt and see if that helped." 

I started from the nios2 command shell and despite finding nios2-terminal and nios2-download, I was unable to see test_bashrc so I could execute it. 

 

UPDATE: 

Just finished a brand new instalation of Quartus 11.0 and Nios2 EDS. 

Had a problem finding nios2-download and nios2-terminal. 

Added to the PATH environment variable: 

C:\altera\11.0sp1\nios2eds\bin and C:\altera\11.0sp1\nios2eds\bin\gnu\H-i686-mingw32\bin 

 

after executing the batch file, the following error happened. 

"bash 5532 c:\altera\11.0sp1\quartus\bin\cygwin\bin\bash.exe: *** fatal error - internal error reading the windows environment - too many environment variables?" 

 

Bit strange isn't it? 

 

NEW UPDATE: 

SUCCESS!!! I changed the order by which the paths (mentioned above) appear on the PATH environment variable. I had them at the end, now their at the beginning. Why? Because I read somewhere on this forum that cygwin has a limited amount of memory for environment variables. 

 

"Hello from Nios II!" :D 

 

Tell me if it work for you. 

 

Cheers, 

LDS

I know it's an old topic, but the problem still exists in 13.0sp1. 

 

I've followed your solution, adding the appropriate files to the environmental path. The nios2-download command is now found, but new errors return: 

 

/cygdrive/c/altera/13.0sp1/nios2eds/bin/nios2-download: line 2: $'\r': command not found.

nois2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 

nois2-terminal: (Use the IDE stop button or Ctrl-C to terminate) 

 

Now what :( this is so frustrating. I spend literally 12 hours not to get a demo working that was provided by altera. Shouldn't this be an out-of-the-box example?

EDIT: ok, I finally solved the above problem by opening each file in sublime and changing the encoding.

This message is related to the file using Windows encoding instead of Unix. The Cygwin command dos2unix can be used to correct the encoding. 

 

I agree that it is pretty lame that the demos do not work "out of the box". Personally, I just start with the schematic of the board and write my own demos.

This is my - now working - version of the test_bashrc (Quartus 14.0 Webedition, win7 64bit): 

 

As mentioned above the file has to be saved with unix style line endings. dos2unix does the job of converting line endings if your editor saves windows style only. 

Maybe nios2-download also has to be converted using dos2unix. 

 

Change /cygdrive/c/altera/14.0 to your correct location.

Bumping an old thread, but this is the top result when I googled my problem and I figured someone might want this fix in future. The SOPC demo wasn't working, the problem can be fixed on windows by creating a DE0_Nano.sh file in the demo_batch directory with the following: 

 

# file: nios2_sdk_shell_bashrc 

 

"$SOPC_KIT_NIOS2/nios2_command_shell.sh" nios2-download DE0_NANO.elf -c 1 -r -g 

"$SOPC_KIT_NIOS2/nios2_command_shell.sh" nios2-terminal -c 1
