IMX93 cannot find phy in RMII mode under 6.6.36 kernel version id

Hello everyone:

I.MX9352 chip, on the same board, using 6.1.22 kernel version, 100M Ethernet port is normal, but after upgrading to 6.6.36 kernel version, the device tree configuration is consistent with 6.1.22, but the phy cannot be scanned. Please help.

Re: IMX93 cannot find phy in RMII mode under 6.6.36 kernel version idI use the mx93a1-ahab-container.img firmware.
I think my chip should be A1.Re: IMX93在6.6.36内核版本下RMII模式下找不到phy id

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!
