Hi Forum,
We have a customized rzg2h Board (taken a reference of rzg2h-hihope board, In the new custom board we replaced realtek with ksz9131RNX.
We used the same pin connection in the hardware and in the kernel config we disabled the realtek and enabled ksz9131 but the phy is non functional.
And we not able to probe and detect the phy.
Could any one here help/point us to the steps required to get this phy up .
Thanks and regards,
Nagaraja
Hi Nagaraja,
You should show the change points of your devicetree, and the kernel boot log.Maybe there are some clues there.
Hi Hung T,
Thanks for the reply,
Here is the the kernel log and my dts entries,
root@hihope-rzg2h:~# dmesg | grep eth0*[ 0.000000] psci: probing for conduit method from DT.[ 2.281423] optee: probing for conduit method.[ 2.512407] ravb e6800000.ethernet: no valid MAC address supplied, using a random one[ 2.520670] mdio_bus e6800000.ethernet-ffffffff: MDIO device at address 0 is missing.[ 2.529054] ravb e6800000.ethernet eth0: Base address at 0xe6800000, de:3d:d1:a1:6e:b0, IRQ 177.[ 7.395309] ravb e6800000.ethernet eth0: failed to connect PHY[ 7.566335] ravb e6800000.ethernet eth0: failed to connect PHYroot@hihope-rzg2h:~# ifconfiglo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:312 errors:0 dropped:0 overruns:0 frame:0 TX packets:312 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:20232 (19.7 KiB) TX bytes:20232 (19.7 KiB)

Do you really have the pins the PHY set to address 7?
Hi,
Thanks for the reply , now My dts entries is as below:
&avb { status = "okay"; pinctrl-names = "default"; phy-handle = <&phy1>; phy-mode = "rgmii-id"; phy1: phy@3 { reg = <0x3>; compatible = "ethernet-phy-ieee802.3-c22"; };};
Self ping is happening and able to ping peer-to-peer But when i try to connect to ping the network, it is not working,
Please guide us what am i missing here. and how do go about it.Please see the attached screenshot.
did you set a MAC address?
Hi Chris,
Yes I set the mac addres in u-boot using setenv ethaddr .
bdinfo shows the mac adress
Then also not able to get ethernet working.
next you should check the board design and verify the signals. maybe put a scope on the pins to make sure data is coming out.
