Hello, I have  Orange Pi One Plus with the kernel 5.15.80 of Armbian 22.11.1 and work well.

, but after upgrading to 23.8.1 kernel 6.1.47 the network interfaces stop working at all.

 

Even I try the 23.05.1, 23.05.6 all have same error which because the kernel is 6.1.x.

Currenly I limited the internet access without the the network.

May I know how to fix it in the console or someone can help to generate the 23.11.1 image for fixed this error.

 Thanks

 

The error message like as below in the console terminal.

[  9.899195] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19)

2024/02/11 update the status.

I use addition USB3 ethernet device to work with the network and run apt upgrade to the kernel 6.1.63.

But still has a error with inside network device eth0.

The below is spec:

I have the same problem on OrangePi 3

This is a problem of interaction between the phy driver and MAC in the Linux kernel.

 

./stmicro/stmmac/stmmac_main.c:928: pr_err("%s: Cannot attach to PHY (error: %d)\n", __func__, ret);

./stmicro/stmmac/stmmac_main.c-894-static int stmmac_open(struct net_device *dev)

./phy_device.c:441:static int phy_attach_direct(struct net_device *dev, struct phy_device *phydev,

./phy_device.c:413:int phy_init_hw(struct phy_device *phydev)

 

It is known that an error will be reported during phy initialization, but I am still looking for the kernel source code for Sunxi Linux 6.1.xx and 5.15.xx.

 

Error code flow:
stmmac_open > stmmac_init_phy > phy_connect > phy_connect_direct > phy_attach_direct > phy_init_hw

I find the phy issue stiil happened in OranpePi3 when using Kernel 6.1.47-current-sunxi64 and 6.12.20-current-sunxi64.

 

@Jack07 @JohnnyLaw 

Do you still have same issue when using 6.X.X verion kernel?

I am trying to downgrade to kernel 5.15.93-sunxi64 and found the eth0 is worked.

I found the dts setting about "ethernet@5020000" was different between kernel 5.15.93 and kernel 6.1.47.

 

We need to make sure the following things are correct:

1. Ethernet driver uses the correct clock/reset

2. GPIO reset can be pulled up

3. MDIO can correctly go to PHY

4. Pinmux correctly sets Ethernet pins
