linking error in 648 program

I tried to replace the cmd file with mycfg.cfg  of the helloworld demo in NDK toolkit,

while I am compiling a 648 program, I got the following message.

__args_main                      C:\dvsdk_1_10_00_26_DM648\xdc_2_95_02\packages\ti\targets\rts6000\lib\boot.a64P

I guess it is caused by missing library. But I don't know how fix it. please help me, thanks

  • If I copy back the cmd file ,everything gonna be OK.

    but many 648 demos only contain cfg file without cmd file. It seems cfg can override cmd. but what I wrote doesn't take the place of original cmd.

    summoning high technicians.
