Missing Libraries in Nios II Software Build Tools for Eclipse

Hello,

for one of my University Courses I am doing a Nios II Project on an DE2-115 Development Board from terasIC.

After adding some new Features in the Platform Designer, I found this error while I was debugging the now non working c code:

Can't find a source file at "/build/arc/temp/823101626/ACDS_lwr/ip/sopc/app/gnu/BUILD/gnu/build-newlib.nios2-elf.x86_64-w64-mingw32/nios2-elf/mno-hw-mul/newlib/libc/stdio/../../../../../../src/newlib-2.2/newlib/libc/stdio/printf.c"

I have no idea what to make of it, other than it now misses this file, where it did not before.

My theory is that some dependencies broke, but as to why they did I do not know.

I am using Quartus 18.1 Lite Edition with the Nios II Software Build Tools for Eclipse

 

Any help would be appreciated. If you need any additional Information let me know

Hi,

 

Can you run project in normal mode instead of debug mode?

Try by cleaning project, regenerating bsp, build project and check.

Also try by adding source file directory by clicking run as->run configuration->source->add C:\intelFPGA_lite\18.1\nios2eds\bin\gnu\src ->apply-> run

 If possible please do attache the project.

 

The printf.c file should be available in directory C:\intelFPGA_lite\18.0\nios2eds\bin\gnu\src\newlib-2.2\newlib\libc\stdio

And this function can be accessed by adding header stdio.h.

 

Regards

Anand

Sadly this did not work. It made no change at all.

For the Project Code, it is below, but it is kind of a mess, but any attempt to tidy it up is making the Project not working correctly.

Thanks Jan,

 

I have used nios2_system.sopcinfo file from project and created a new eclipse project with name testlite and successfully generated elf without any error.

  1. Delete your software folder and recreate the eclipse project by importing .sopcinfo file.
  2. or import the software file attached.

testlite.JPG

 

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

 

Best Regards,

Anand

Hi Anand,

unfortunatly this hasn't fully resolved my problem, and I think I have not described my problem precisely enough. The Code did always compile without errors or warnings. However, none of the "debug" printf or alt_prinft statements where printet on the Nios II console. The write commands to the lcd do not work either. Sadly this error persists. The missing Libraries error only surfaced when I ran the code in debug mode. This error however has gone away and was replaced with this error message: 304   HAL/src/crt0.S: No such file or directory.

 

Thank you for your Assistance so far, and any more help would be appreciated.

 

Regards,

Jan

Hi Jan,

 

Apologizes for late reply.

We dont have DE2-115 Development Board kit to replicate the given design however i have tried to recreate the scenario using other kit. We can eliminate the such error using step-over while debugging instead of step-into. try by pressing resume key while giving write commands to the lcd hope it helps.

Anand

Hi,

sadly this did not help.

Another thing that i tried was to revert to a previus stage of the project and reused the eclipse project from it. That code worked fine. I suspect one or more files got corrupted or my Nextcloud is at fault with its way of dealing with modified files.

Either way, Everything works now and thats what I need.

Thank you very much for your help. It was very much appreciated.

Also I am sorry for my late reply as well.

 

Thank you for your time.

Regards,

Jan
