IMX93在6.6.36内核版本下RMII模式下找不到phy id

大家好：

      I.MX9352芯片，在同一个板子上使用6.1.22内核版本百兆网口是正常的，但是升级6.6.36内核版本之后，设备树配置与6.1.22一致但是扫描不到phy。请求帮助。

Hi @yangx!

IF your board works with kernel 6.1.22 it is normal that should not work on kernel 6.1.36 and latest kernels.

The kernel 6.1.22 and 6.1.22 works only on iMX93 with silicon version A0 the silicon version A1 works with kernel 6.1.36 an latest kernel versions.

Please confirm that you have A1 silicon version version to use the latest kernel versions if not, you have to use the 6.1.22 kernel version .

Best Regards!

是使用的 mx93a1-ahab-container.img 固件
我想我的芯片应该是A1的，
