hi nv team,
I use the rgmii port on my custom board I have follow the instruction on the DeveloperGuide.
1. modify the pinmux excel, and genrate the new dtsi file
2. modfiy the device tree the enable rgmii
now the rgmii port can work, but it can only wrok in 10M.(when I plugin the Network cable, it first auto negotiation to 1G, but quickly, the net down. after about 15s, the net up with the speed of 10M)
the net can work, because I can ping each other between orin and my host computer.
here is the dmesg.
eth.log (7.5 KB)
jetpack: 5.0.2
phy:88E1512
so any suggestion about this issue
here is the dmesg file
