OMAPL138 Syslink app runs problems

I encounter a problem that puzzled me many days,I can't find out the answer,I used the syslink2_21_02_10 ,to communicate dsp with arm,the example is led.

DSP compile options as follow describled:

sysbios_6_35_04

ipc_1_25_03_15

TI_CGT_C6000_7.4.4

xdctools_3_25_03_72.

kernel is in CD -- 2.6.33-rc4

now ,when runs ,it counters following problem: Ipc_attach: Ipc_procSyncStart failed!It is a finite loop.Other parts of the application are no errors , led also can flashes normally.
