Change Ethernet_EQOS to Ethernet_FEC in i.MX8M Plus LPDDR4 EVK

[Jimmychea]

In my custom board, it only contains one Ethernet_EQOS, but would like to remove the TSN supported feature, what should i need to change in dts or other files ?

Hi @Jimmychea 

I hope you are doing well.

In IMX8MP, there are two ethernet ports, eth0(fec) and eth1(eqos). Hence to use fec, one can simply enable that feature in device tree file by "status = okay" in fec node.

To remove eqos, one can disable it in the device tree file by status = "disabled"; property.

Thanks & Regards

I would like to use the eqos node, but i don't want the TSN feature, is that possible to do it ?

Please find the answer below.

One can try by disabling the driver configuration given in the Real-time Edge Software User Guide section. 4.1.2.2 Tsntool. 

As Eth1 port of Imx8mp comes with TSN support, NXP does not recommend doing so.
