Hello everyone,

I seem to be stuck at trying to create a working OpenWRT firmware for a board that is based on the MT7620A but uses a QCA8337 (Atheros) switch. I have no clue how to modify one of the MT7620A DTS files to make it attach to and use the QCA8337 switch.

The only config that boots is the MT7620A + MT7530 - that sees the USB ports and GPIOs but doesn't appear to be able to ping or do anything useful with the Ethernet ports.

Can anyone give me a hand with this? This board appears to be rather unique, I couldn't find any supported boards that used the MT7620A but an Atheros (QCA8337) switch.

Boot log is attached if it helps. Thank you!
Razvan

All external atheros switches are driven by ar8216.ko through mdio-bus. For MT7620A mdio-bus may be:
- internal (see mt7620a.dtsi);
- virtual mdio-gpio (use two free gpios).
You can find examples in dts-files for other targets.

Thank you Serge! Is there anything I need to do to enable the use of that ar8216 driver? I've enabled it in kernel_menuconfig but the boot log still says

ralink_soc_eth 10100000.ethernet: loaded mt7620 driver

I've also brought it to the point where 3 out of the 5 ports on my board worked. I could ping out and receive packets on ports 1, 4 and 5. Ports 2 and 3 were completely off (no LED lights, nothing). They appeared to be turned off as soon as the board booted up (they worked in uBoot to flash it), so I'm guessing that the MT7620A driver "sort of" works with the QCA8337 - that was a bit weird, I expected it to either fail altogether or work - I didn't expect a partial failure like this.

I'm not sure what made it work like this, I'm trying to do a new build from scratch to see if I can reproduce this. But I still think the board is simply ignoring the ar8216 driver and just going with the Ralink drivers (something must need to be changed in the DTS...).

Any suggestions? What am I missing?

Thank you,
Razvan

As a quick update, here's the dmesg from the time it boots up (with the wrong driver) and sees 3 out of 5 ports. The Atheros AR8216 driver is disabled at this point.

And here's a dmesg with the Atheros AR8216 driver enabled - it is detected now, but not picked for use and switch0 appears as "mdio-bus" in swconfig. Packets do not flow in this case (and I'm showing two switches, one Mediatek and one mdio-bus (I'm assuming the Atheros one) ).

I'm guessing that the Atheros AR8216 needs some additional settings to work - not sure where I would put those. I'm using the following DTS (it's the standard MT7620A+MT7350 one - it was the only one that booted up without a kernel panic).

/dts-v1/;

Your dts-file desribe only external mt7530 gigabit switch and say nothing of atheros ar8337. I think that you may try something like

/dts-v1/;

/include/ "mt7620a.dtsi"

/ {
    compatible = "ralink,mt7620a-eval-board", "ralink,mt7620a-soc";
    model = "Ralink MT7620a + AR8337 evaluation board";

    palmbus@10000000 {
        spi@b00 {
            status = "okay";

            m25p80@0 {
                #address-cells = <1>;
                #size-cells = <1>;
                compatible = "s25fl064k";
                reg = <0 0>;
                linux,modalias = "m25p80", "s25fl064k";
                spi-max-frequency = <10000000>;

                partition@0 {
                    label = "u-boot";
                    reg = <0x0 0x30000>;
                    read-only;
                };

                partition@30000 {
                    label = "u-boot-env";
                    reg = <0x30000 0x10000>;
                    read-only;
                };

                factory: partition@40000 {
                    label = "factory";
                    reg = <0x40000 0x10000>;
                    read-only;
                };

                partition@50000 {
                    label = "firmware";
                    reg = <0x50000 0x7b0000>;
                };
            };
        };
    };

    pinctrl {
        state_default: pinctrl0 {
            gpio {
                ralink,group = "i2c", "uartf";
                ralink,function = "gpio";
            };
        };
    };

    ethernet@10100000 {
        status = "okay";

        pinctrl-names = "default";
        pinctrl-0 = <&rgmii1_pins &rgmii2_pins &mdio_pins>;

        ralink,port-map = "llllw";

        port@5 {
            status = "okay";
            ralink,fixed-link = <1000 1 1 1>;
            phy-mode = "rgmii";
        };

        mdio-bus {
            status = "okay";

            phy0: ethernet-phy@0 {
                reg = <0>;
                phy-mode = "rgmii";
        device_type = "ethernet-phy"; 
            qca,ar8327-initvals = < 
            0x00004 0x7600000   /* PAD0_MODE */ 
            0x00008 0x1000000   /* PAD5_MODE */

            >; 
            };
            phy4: ethernet-phy@4 {
                reg = <4>;
                phy-mode = "rgmii";
            };
        };
    };

    gsw@10110000 {
        ralink,port4 = "gmac";
    };

    pcie@10140000 {
        status = "okay";
    };

    ehci@101c0000 {
        status = "okay";
    };

    ohci@101c1000 {
        status = "okay";
    };
};

I'm not sure of ar8327-initvals. And possibly gsw@10110000 section must be totally remove from dts-file (not only mt7530 switch).

Thank you Serge! That has helped a bit, now the Atheros ar8216 driver on longer probes blindly but it still doesn't appear to work. I've tried various qca,init-vals values from the net but none of them worked. The kernel panics as soon as the boot is complete, see below (truncated a bit at the right, I copied it from a limited width serial terminal).

Current DTS (just the Ethernet section) looks like this:

        };

        mdio-bus {
            status = "okay";

            phy0: ethernet-phy@0 {
                reg = <0>;
                phy-mode = "rgmii";

            };
            phy4: ethernet-phy@4 {
                reg = <4>;
                phy-mode = "rgmii";
            };
            phy1f: ethernet-phy@1f {

                phy-mode = "rgmii";

        };
    };

        gsw@10110000 {
                ralink,port4 = "gmac";
                mediatek,mt7530 = <1>;
        };

I've had to keep the mediatek,mt7530 line, without it the Atheros driver doesn't appear to be loaded:

[    0.800000] ralink_soc_eth 10100000.ethernet: generated random MAC address 72:15:88:88:f0:18
[    0.800000] libphy: mdio: probed
[    0.800000] ralink_soc_eth 10100000.ethernet: using fixed link parameters
[    0.800000] ralink_soc_eth 10100000.ethernet: loaded mt7620 driver
[    1.120000] ralink_soc_eth 10100000.ethernet eth0: ralink at 0xb0100000, irq 5
[    1.140000] rt2880_wdt 10000120.watchdog: Initialized

The same thing happens I remove the gsw@10110000 section altogether - no Atheros driver loaded, no switch detected.

I wonder why the Atheros driver only gets probed when the gsw@10110000  section is still present and the mt7530 switch is enabled... maybe it doesn't look for a driver if that line is missing???

Thank you once again,

Ok, I've tried a few other configurations but I can't seem to be able to make this work. So is there someone (maybe Serge or someone else) that would be willing to help (for a fee)? I can either give you remote access to one of these boards (SSH into a Linux machine that has an USB serial adapter going into the board console, an Ethernet cable going into port #2 (port #1 works, we need all 5 to work) and a remote power switch if you need to turn it on/off).

We only have two of these boards at this point, so I can't ship one to you, but we should be getting more in a couple of weeks. If anyone feels up to it, please PM me. Once again, we will pay you for your effort.

To summarize, we need the MT7620A to detect the QCA8337 switch and use it to access each of the 5 Ethernet ports separately. I can provide you a config that makes it see 3 of the ports (1, 4 and 5) using the MT7620 switch, not Atheros. It works ok with those 3, we need all 5.

If you think I should post this somewhere else as well, please let me know.

Thanks again,
Razvan

The discussion might have continued from here.
