i.MX8M调用失败

[lizboxy]

请教一下，通过调试发现，在函数 cdns_mhdp_training_start(struct cdns_mhdp_device *mhdp) 里面读取事件发现： if (event[1] & CLK_RECOVERY_FAILED) DRM_DEV_ERROR(mhdp->dev, "clock recovery failed\n"); else if (event[1] & EQ_PHASE_FINISHED) return 0; 这里失败的只要原因是 event[1]=0x40 即 EQ_PHASE_FAILED 请问这个是因为什么呢？

What version of BSP are you using?

Which board are you using?

Which source code are you talking about?
