用的是TCI6614的EVM板TMDX320TCI6614LXE，使用debug单步运行Brighton Feng提供的AIF2_LTE_TDD和AIF2_LTE_FDD等例程，当运行到KeyStone_DDR_init (66.667, 20, 1, NULL);函数时，Console输出如下：
[C66xx_0] Initialize DSP main clock = 122.88MHz/29x236 = 999MHz
Initialize DDR speed = 66.67MHzx20/1 = 1333.340MTS

DDR reinitialization 10
请问这是否是正常现象？此外，在单步运行LTE_TDD和LTE_FDD的例程时，会卡在这里（_mfence();处）不动：
CACHE_invAllL1p(CACHE_WAIT);
CACHE_wbInvAllL1d(CACHE_WAIT);
CSL_XMC_invalidatePrefetchBuffer();
_mfence();
请问这该如何解决？谢谢！
