Build Outputs

Hello:

I've created a NIOS II IDE Project.

I build my main.c which contains the simple Hello World porgram with no errors.

The IDE keeps running and generated the following "error" message.

Kind Description Resource In Folder Location

Error 49 PM - (SEVERE) elf2flash: Boot copier overlaps data in flash[Oct 25, 2004 2] Prototype line 46

Now my real probelm is that I can't get at the output from the compile of main.c. It has flashed by in the C-Build window and that window keeps getting cleared several times in the build process.

Does anyone know how to get at build output messages??

George

    I have the same question. Just like this:

    Kind Status Priority Description Resource In Folder Location

    Error *** [ext_flash.flash] Error 5 hello_world_1

    Error 32 AM - (??) elf2flash: Error generating Flash file, exiting[Oct 26, 2004 8] hello_world_1 line 10

    Error 32 AM - (??) elf2flash: Error reading boot copier[Oct 26, 2004 8] hello_world_1 line 10

    Error 32 AM - (??) elf2flash: Read error: File not found: /boot_loader_cfi.srec[Oct 26, 2004 8] hello_world_1 line 10

    I dont understand the "File not found: /boot_loader_cfi.srec", because the file boot_loader_cfi.srec is really there!

    My original question is how to save the output of the C-Build processes to view later.

    Once I can see the outputs I can start to track problems that I(you) have.

    Hello George,

    You can capture the output of the C build process by executing make directly from the command line.

    1. Launch Start -> Programs->Altera -> Nios II Development Kit 1.1-> Nios II SDK Shell

    2. Change directory to the Release or Debug folder of your project

    (depending on whether the configuration setting in the Application Project properties page of the Nios II IDE is set to Release or Debug)

    3. make

    This can only done after the project has been created and a build attempted in the Nios II IDE, so that files, such as the linker script file, and folders, such as Debug, can be generated by the Nios II IDE.

    You can then adjust the properties of the shell by right-click on the window title bar, select properties, then adjust the screen buffer under the layout tab to be large enough to capture the entire output of make. Also, make can be invoked with a verbose-mode flag which will print out the specific commands which are invoked during the build to help you to analyze the problem.

    Best regards,

    Stephen

    Staying within the IDE, you can try this setting: Window->Preferences->C/C++->Build Console and uncheck the option "Always clear C-Build view before building". This should leave the output in the C-build view. In this case you may also want to increase the number of lines in the console (that setting is also on the same preference page). You can then view or copy build output direct from the C-build view without leaving the IDE.

    @nios_xx:

    I had maybe the same problem as you. After hours of searching http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif I found out that I had a different (light) version of cygwin1.dll on my system (in my case from OpenSSH). After I have deleted it, the building-process from the IDE always aborted with "cygwin1.dll not found". After that I had the reinstall Quartus AND Nios II -> Now it works fine. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif
