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 #Kernnel 5.15.93-sunxi64 ethernet@5020000 { compatible = "allwinner,sun50i-h6-emac\0allwinner,sun50i-a64-emac"; syscon = <0x31>; reg = <0x5020000 0x10000>; interrupts = <0x00 0x0c 0x04>; interrupt-names = "macirq"; resets = <0x04 0x21>; reset-names = "stmmaceth"; clocks = <0x04 0x54>; clock-names = "stmmaceth"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <0x32>; phy-mode = "rgmii-id"; phy-handle = <0x33>; phy-supply = <0x34>; phy-io-supply = <0x35>; allwinner,rx-delay-ps = <0xc8>; allwinner,tx-delay-ps = <0xc8>; phandle = <0x78>; mdio { compatible = "snps,dwmac-mdio"; #address-cells = <0x01>; #size-cells = <0x00>; phandle = <0x79>; ethernet-phy@1 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <0x01>; reset-gpios = <0x1f 0x03 0x0e 0x01>; reset-assert-us = <0x3a98>; reset-deassert-us = <0x9c40>; phandle = <0x33>; }; }; }; #Kernel 6.1.47-current-sunxi64 ethernet@5020000 { compatible = "allwinner,sun50i-h6-emac\0allwinner,sun50i-a64-emac"; syscon = <0x32>; reg = <0x5020000 0x10000>; interrupts = <0x00 0x0c 0x04>; interrupt-names = "macirq"; resets = <0x06 0x21>; reset-names = "stmmaceth"; clocks = <0x06 0x54>; clock-names = "stmmaceth"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <0x33>; phy-mode = "rgmii-id"; phy-handle = <0x34>; phy-supply = <0x2e>; phy-io-supply = <0x35>; allwinner,rx-delay-ps = <0xc8>; allwinner,tx-delay-ps = <0xc8>; phandle = <0x79>; mdio { compatible = "snps,dwmac-mdio"; #address-cells = <0x01>; #size-cells = <0x00>; phandle = <0x7a>; ethernet-phy@1 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <0x01>; reset-gpios = <0x1e 0x03 0x0e 0x01>; reset-assert-us = <0x3a98>; reset-deassert-us = <0x9c40>; phandle = <0x34>; }; }; };

I am trying to downgrade to kernel 5.15.93-sunxi64 and found the eth0 is worked. pi@orangepi3:~$ dmesg | grep eth0 [ 18.467932] dwmac-sun8i 5020000.ethernet eth0: PHY [stmmac-0:01] driver [RTL8211E Gigabit Ethernet] (irq=POLL) [ 18.468969] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 18.469701] dwmac-sun8i 5020000.ethernet eth0: No Safety Features support found [ 18.469727] dwmac-sun8i 5020000.ethernet eth0: No MAC Management Counters available [ 18.469734] dwmac-sun8i 5020000.ethernet eth0: PTP not supported by HW [ 18.475463] dwmac-sun8i 5020000.ethernet eth0: configuring for phy/rgmii-id link mode [ 20.510690] dwmac-sun8i 5020000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx [ 20.510735] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

My log : https://paste.armbian.com/idomububex 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?

@Werner I will close this Topic and discuss the issue in the old one.

@Werner Yes, My SBC model is "OrangePi3", not LTS.

Now I am trying to downgrade Kernel back to 5.51.X and figure out it.

@Werner Got it! Thank you for your help. https://paste.armbian.com/idomububex Provided the link.

The eth0 device does not work when using 6.1.47-current-sunxi64 and 6.12.20-current-sunxi64 kernels. There will be the following errors in the kernel log. pi@orangepi3:~$ dmesg | grep eth0 [ 16.997431] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 16.998219] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 19.284111] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 19.284754] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 19.308140] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 19.308738] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 19.334063] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 19.334754] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 19.358727] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 19.359417] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 151.380407] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 151.381105] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 157.928629] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 157.929360] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 320.009515] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 320.010271] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 320.037458] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 320.038169] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 320.062716] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 320.063428] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) [ 320.082662] dwmac-sun8i 5020000.ethernet eth0: Register MEM_TYPE_PAGE_POOL RxQ-0 [ 320.083389] dwmac-sun8i 5020000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19)

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) ./stmicro/stmmac/stmmac_main.c:299:static int stmmac_init_phy(struct net_device *dev) ../phy/phy_device.c:371:struct phy_device * phy_connect(struct net_device *dev, const char *bus_id, ./phy_device.c:336:int phy_connect_direct(struct net_device *dev, struct phy_device *phydev, ./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.

Hi @Igor, Thank you for your useful and honest advice. I appreciate it. https://github.com/CGarces/rtl8192eu-linux-driver/commit/d32dfa2c2b2a1b8e75d163d23e9e18f750ebfbe4 I have found that someone has provided a fix for Tx power in the rtl8192eu driver. I am currently compiling and testing this method to work in the RTL8189FS driver.

Thank you for your explanation and contribution, I appreciate and admire it. https://linux-sunxi.org/Wifi#RTL8189FTV I will try to look into rtl8189fs, thank you very much!

At present, I tested and found that wlan0&wlan1 can only connect to the same SSID at the same time. However, the information in iw points out that the two have different phy numbers.

pi@orangepipcplus:~$ sudo iwconfig wlan0 txpower 20 Error for wireless request "Set Tx Power" (8B26) : SET failed on device wlan0 ; Operation not permitted. pi@orangepipcplus:~$ sudo iw dev wlan0 set txpower fixed 2000 pi@orangepipcplus:~$ I tried to use iwconfig and iw commands to configure txpower. However, iwconfig will give an error response of "Set tx power". iw does not respond to any messages.

I'm not sure if this is related to a limitation of the rtl8189fs firmware. I tried closing the wlan0 interface first and then configuring txpower, but it didn't seem to work. After executing the command, check dmesg and no relevant logs are found.
