error when i run gdb?

Hi,

I write a app code and build it successfully and run well in my target board. But why show following message when i use gdb debug in nios2 IDE? I don't know these parameter -Ttext 0xfe30040 -Tdata 0xfe36a44 -Tbss 0xfe3822c how to generate? if overlay why i can run well in target board? when i reduce my code, it will be fine.

Thanks.

no emulation specific options.
