Sorry can you elaborate further? I am not sure if I understand the problem clearly. They are GPIOs how can these be swapped?

There seems to be an issue with every dts patch I have found for this board, even the one in the olimex buildroot-imx repo. The ethernet reset GPIOs are swapped between the 2 interfaces.  For example, buildroot-imx/board/olimex/imx8mp/linux/0001-dts-add-imx8mp-olimex.patch:
&eqos {
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_eqos>;
    phy-mode = "rgmii-id";
    phy-handle = <&ethphy0>;
        phy-reset-gpios = <&gpio4 02 GPIO_ACTIVE_LOW>;
        .
        .
        .
pinctrl_eqos: eqosgrp {
        fsl,pins = <
            .
                        .
                        .
            MX8MP_IOMUXC_SAI2_RXC__GPIO4_IO22        0x19
        >;
    };

I was wondering why my yocto build only had 1 ethernet port come up, the patch I was using was messed up slightly different and managed to have the second ethernet configured close enough to work.

Why didn't you just solder wires to the pads of the reset button. Just add wire at each side of the button and add a second button at the box...

Measure between the pads of R28 of continuality and see if there is connection.

Hello. Thanks for your response.

Really I wanted to export that button to my outer box, that will be a container for my A64. So I can turn it on and off.

Well, by now I just removed the 1K resistor R28 and pressing the on board pwr01 button, the shutdown behavior returns.

Please any advice on getting this functionality working, will be appreciated.

Thanks

hi,
Can anyone confirm whether MOD-WIFI-RTL8188EUS-ANT (https://www.olimex.com/Products/USB-Modules/WiFi/MOD-WIFI-RTL8188EUS/) is compatible with the A64-OLinuxino ?

Thanks
