Linux/PROCESSOR-SDK-AM437X: How to config double MAC in Am437x-gp-evm

Tool/software: Linux

Hi,

I'm using customed board basing on am437x-gp-evm with two MAC ports. It works well in the old ti-sdk-01.00.00.03. We update to sdk-05.01.00.11 for its support to bluetooth and wireless. I modified the am437x-gp-evm.dts according to the old one, but it cann't work:

root@am437x-evm:~# ifconfig -a
lo        Link encap:Local Loopback
          inet addr:127.0.0.1 Mask:255.0.0.0
          inet6 addr: ::1%763612/128 Scope:Host
          UP LOOPBACK RUNNING MTU:65536 Metric:1
          RX packets:162 errors:0 dropped:0 overruns:0 frame:0
          TX packets:162 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:12300 (12.0 KiB) TX bytes:12300 (12.0 KiB)

sit0      Link encap:IPv6-in-IPv4
          NOARP MTU:1480 Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

I cann't find eth0, eth1 as my expected.

I find errors from kernel start:

[    1.050951] pinctrl-single 44e10800.pinmux: pin PIN16 already requested by 44e10800.pinmux; cannot claim for 4a100000.ethernet
[    1.062448] pinctrl-single 44e10800.pinmux: pin-16 (4a100000.ethernet) status -22
[    1.069981] pinctrl-single 44e10800.pinmux: could not request pin 16 (PIN16) from group cpsw_default on device pinctrl-single
[    1.081435] cpsw 4a100000.ethernet: Error applying setting, reverse things back
[    1.088794] cpsw: probe of 4a100000.ethernet failed with error -22

I don't know how to correct it.

Is there anything more to config?or need to config kernel? I attact the am437x-gp-evm.dts and kernnel start log here.

Best Regards!
