SafeTI诊断库 TCM RAM ECC问题

您好,运行SafeTI诊断库时,程序到下面两部分语句时

1、/* Run 2Bit ECC test on TCM RAM */
     retVal = SL_SelfTest_SRAM(SRAM_ECC_ERROR_FORCING_2BIT, TRUE, &failInfoTCMRAM);
     INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);

2、/* Run RAD Self tests on TCMRAM */
        retVal = SL_SelfTest_SRAM(SRAM_RADECODE_DIAGNOSTICS, TRUE, &failInfoTCMRAM);;
        INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);

会跳转到

#pragma INTERRUPT ( _excpt_vec_abort_pref, PABT)
void _excpt_vec_abort_pref()
{
 while(1);
}

然后就在这一直循环,请问是什么原因?
