I am new to NIOS II EDS. I am trying to generate a calculato using the nios system.
I tried to build and run my code. First, I got an error with Target connection. I tried to refresh the connection, but the system would not detect the development kit. Now I see two errors in the problems window, which I don't understand. I am attaching a screenshot of the error. Can somebody please help

Hi Reba,
Provide a console message log.
Also, share information about your design, Development kit & Tool version & edition used.
If possible share your project.

Hi Reba,
Your consol message is showing build error, Error on bsp folder clean the project & bsp and regenerate the bsp & build project and check.
If you face same issue try to recreate the eclipse project with the correct .sopcinfo file.
Regards
Anand
