Hello everyone, I am using broadcom BCM52681E chips, according to the official register configuration example, given the chips for adaptive model, the other for IXIA testing equipment, when I set the IXIA to 10 m, adaptive, test communication is normal, but I found that IXIA send data to the 52681 e sometimes make mistakes, I use the oscilloscope observation PHY chip s3mii receiving data synchronization signals and data, found that displacement happens, namely send lead code and data of 55 55 should have 55 55 55 55 55 d5 ff, and dislocation after into 55 55 55 55 55 fd, I tried many ways can't solve, hope to you to ask, what exactly is this situation, we have encountered this kind of situation?
