Do you know if using only the Nios II, without the HPS will it work? How did you make to run the C program with the I2C functions in Eclipse? I didn't find the .sopcinfo in your design . Thank you.

    Hello,

    You have the Qsys file, so you can generate the sopcinfo from it easy. After generating the Qsys file, you will get the sopcinfo file. Use this file to create your hello world project.

    Yes sure, you can use Nios II only. This was one of my designs which combines Nios II and HPS. I am attaching a simpler version of qsys file.

      Hello,

      I tried to do my design again based on your Qsys file and it did not work. I put the SCL and SDA on an oscilloscope, but the output was just noise, nor the clock in the SCL was generated. In Qsys, I added the OpenCores I2C component in Tools > Options > IP Search Path, is this correct? Do I need to do anything else? Because the other settings and procedures are the same as your design. Thank you so much for helping me.
