Error while running Linker I don’t know what happened,Who can help me?
   

I just tried building it and it completed with zero errors and zero warnings. Did you change _anything_?

Thank you,
I change nothing ,I download FreeRTOSV6.0.1,and  just tried building it,it is OK,but FreeRTOSV6.0.0, will give the lingker error
