    Hello chen,

    That function is part of the run-time library. Are you including the C6000 run time library for your project (rts64plus.lib)?

    Thanks

    Didn't realize you are using a BIOS project. The issue is that some symbols are defined twice. Are you trying to build some example or is this a custom project?

            Hi Ki:

                 My project is a custom project, I used bios is "bios_5_31_07" ,  dependent project is pds_lib.pjt  , ative project is dm6437_evm_video_st_sample.pjt, 

                                                     

                               I add run time libarary that generate a new error

    .

             if I don't add runtime libarary ，it generate other error:

                                                 

                      so , how to do this!

                      Best Regards!

        Hi, I'm a rooky. I faced the similar problem and searched this. Finally I made it up. I think it may do some benefit if you put enough source files related into your project. Sincerely hope you can get throuth it! Great bless!
