Apply s32g274 bsp35.0 to add the PHY chip ADIN1200 in U-Boot

Apply s32g274 bsp35.0 to add the PHY chip ADIN1200 in U-Boot. After U-Boot starts, the register of the PHY can be read by the mii command, but the input ping is 10.0.0.1. It will directly prompt "Failed to enable rx_rgmii clock". What's the problem here?

Hello @sdx111,

Thanks for the information. To narrow it down even more, please share the following:

• The complete node definition of  gmac0: ethernet@4033c000 in ATF (fdts/s32cc.dtsi)
• Please add the return value to the print of the error in eth.c#L312 :
  • dev_err(gmac_dev, "Failed to enable %s clock, returned %d\n", rx, ret);
• If you are aware of any relevant change applied to your u-boot or ATF configuration that might be related to this problem please also share it

Thanks!

The ADIN1200 is connected to GMAC0 and uses the RGMII connection method.

The result after executing the command is shown in the attachment.

Hello @sdx111,

Thanks for reaching out to us. Please execute the following commands in u-boot and share the output:

=> printenv
=> xpcs list

Please also let me know which interface (GMAC, PFE0, PFE1 or PFE2) and pins you are using to connect to the ADIN1200.

Thanks
