The OpenMesh A42 uses labels next to the ethernet ports to identify the first and second ethernet port. The first ethernet port's MAC address is also printed prominently on the label in the center of the housing.
The board can also be powered up only using POE. It is therefore likely that the ethernet cable to the internet is attached to the first ethernet port which is also the active POE port. For a firmware without automatic internet detection (like OpenWrt), it is therefore logical to use this port as the default WAN port. The configuration for each port are: first ethernet port: * phy_mdio_addr: 4 * QCA8072 port bit: BIT(5) * u-boot mac address entry: ethaddr * active POE second ethernet port: * phy_mdio_addr: 3 * QCA8072 port bit: BIT(4) * u-boot mac address entry: eth1addr As Mark Rutland pointed out [1], user-accessible ports with well defined labels should be mapped accordingly with the aliases. This is mostly done already by qcom-ipq4019.dtsi which maps ethernet0 to &gmac0 and &gmac1. Only the gmac0 and gmac1 entries have to be adjusted accordingly to use the correct configurations for the ports. Not configuring the gmac entries as shown above, doesn't only affect the names of the virtual interface names but also swaps the mac addresses of the ports. The first ethernet port will then no longer use the mac address which is printed on the device. [1] https://patchwork.kernel.org/patch/9133903/ Signed-off-by: Sven Eckelmann <sven.eckelm...@openmesh.com> --- I was informed that the patch <https://git.openwrt.org/?p=openwrt/staging/mkresin.git;a=commit;h=9a6d5bd049568e175d45415f51b3cf569ebd7479> was not actually from Christian Lamparter. His original patch <https://github.com/chunkeey/LEDE-IPQ40XX/commit/847c09d2b53684180297bdb056bda08f1c3333f8> didn't contain the gmac0 <-> gmac1 swap. So I have to apologize to him for wasting his time while trying to discuss changes which he actually didn't do. Btw. I don't have a good picture at the moment but you can check some photo from heise to see some of the labels <https://www.heise.de/ct/zcontent/18/03-hocmsmeta/1517536820829720/contentimages/image-1516109563177267.jpg> --- target/linux/ipq40xx/base-files/etc/board.d/02_network | 2 +- .../ipq40xx/files-4.14/arch/arm/boot/dts/qcom-ipq4018-a42.dts | 8 ++++++++ 2 files changed, 9 insertions(+), 1 deletion(-) diff --git a/target/linux/ipq40xx/base-files/etc/board.d/02_network b/target/linux/ipq40xx/base-files/etc/board.d/02_network index 8e9a1889d1..d25a039f2d 100755 --- a/target/linux/ipq40xx/base-files/etc/board.d/02_network +++ b/target/linux/ipq40xx/base-files/etc/board.d/02_network @@ -33,7 +33,7 @@ glinet,gl-b1300) "0u@eth0" "3:lan" "4:lan" ;; openmesh,a42) - ucidef_set_interfaces_lan_wan "eth0" "eth1" + ucidef_set_interfaces_lan_wan "eth1" "eth0" ;; meraki,mr33) diff --git a/target/linux/ipq40xx/files-4.14/arch/arm/boot/dts/qcom-ipq4018-a42.dts b/target/linux/ipq40xx/files-4.14/arch/arm/boot/dts/qcom-ipq4018-a42.dts index 3d56a6ef52..fcc22276ba 100644 --- a/target/linux/ipq40xx/files-4.14/arch/arm/boot/dts/qcom-ipq4018-a42.dts +++ b/target/linux/ipq40xx/files-4.14/arch/arm/boot/dts/qcom-ipq4018-a42.dts @@ -210,6 +210,14 @@ }; &gmac0 { + qcom,phy_mdio_addr = <4>; + qcom,poll_required = <1>; + qcom,forced_speed = <1000>; + qcom,forced_duplex = <1>; + vlan_tag = <2 0x20>; +}; + +&gmac1 { qcom,phy_mdio_addr = <3>; qcom,poll_required = <1>; qcom,forced_speed = <1000>; -- 2.11.0 _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
