TMS320F28388D: TMS320F28388D的Ethercat phy芯片DP83822I 更换成了DP83822IF后无法被Twincat识别

你好,我们在测试F28388的Ethercat 功能时,将F28388D controlcard 的 DP83822I 更换成了DP83822IF(为了未来支持光纤),出现了Twincat不能识别的情况。

1 在 TMDSCNCD28388D 开发板上将P0或P1 的DP83822I 更换成了DP83822IF(只是更换phy),出现TwinCat 只能扫描出device1的情况,且通过 wireshark检测不到开发板回复报文。测试工程为C2000Ware_3_04_00_00\libraries\communications\Ethercat\f2838x\examples\f2838x_cm_cia402_solution

2 更换TMDSCNCD28388D 开发板Ethernet 口的DP83822I 为DP83822IF,DP83822IF在开发板的Ethernet口却能正常。测试工程为C2000Ware_3_04_00_00\libraries\communications\Ethernet\third_party\lwip 

 DP83822IF 与DP83822I使用的同样的datasheet,硬件boot应该一致。请问DP83822IF 在配置Ethercat时还需要其他设置条件吗?
