您好 TI 专家：
我们将 SDK11.0 和 CPSW9G 本机驱动器用于我们的项目、网络拓扑、如下所示：
SERDES1-Lane2-SMGII1 -->100Base-T1 (TI-DP83TC814S)
SERDES1-Lane2-SMGII2 -->100Base-T1 (TI-DP83TC814S)
SERDES2-LANE0-SMGII5 -->固定链路 (MCU-RH850)
SERDES2-LANE1-SMGII6 --> 1000Base-Tx (88EA1512)
SERDES2-Lane2-SMGII7 --> 1000Base-T1 (TI-DP83TG720S)
SERDES2-LANE3-SMGII8 --> 1000Base-T1 (TI-DP83TG720S)
我们的定制电路板运行数小时后、出现以下错误。所有网络都崩溃
