I managed to get libremesh branch openwrt-18.06 running on an espressobin https://openwrt.org/toh/hwdata/globalscale/globalscale_espressobin_v5_0_1 It uses the following switch (Marvell Topaz 88E6341). The espressobin exposes 3 ports (2 for lan and 1 for wan) http://wiki.espressobin.net/tiki-index.php?page=Topaz+Switch Which has been supported using MDIO since 18.06 https://openwrt.org/toh/views/toh_admin_vlan?dataflt%5B0%5D=switch_%3DMarve… But I'm struggling with the right /etc/config/lime for this specific switch When the system boots it has the following devices off of eth0 lan0 lan1 wan config lime 'system' option domain 'lan' option hostname 'TEST-%M4%M5%M6' config lime 'network' list protocols 'ieee80211s' list protocols 'lan' list protocols 'anygw' list protocols 'bmx6:13' list resolvers '4.2.2.2' list resolvers '141.1.1.1' list resolvers '2001:470:20::2' option primary_interface 'eth0' option main_ipv4_address '10.%N1.0.0/16' option main_ipv6_address '2a00:1508:0a%N1:%N200::/64' option anygw_mac 'aa:aa:aa:%N1:%N2:aa' option anygw_dhcp_start '2' option anygw_dhcp_limit '0' option bmx6_over_batman 'false' option bmx6_mtu '1500' option bmx6_pref_gw 'none' option use_odhcpd 'false' option bmx6_publish_ownip 'false' option bmx6_wifi_rate_max '54000000' config lime 'wifi' list modes 'ap' list modes 'apname' list modes 'ieee80211s' option ieee80211s_mesh_id 'LiMe' option adhoc_mcast_rate_5ghz '6000' option ap_ssid 'test' option distance '1000' option ieee80211s_mesh_fwding '0' option apname_ssid 'test/%H' option adhoc_bssid 'ca:fe:00:c0:ff:ee' option htmode_5ghz 'HT20' option channel_2ghz '11' option adhoc_mcast_rate_2ghz '24000' option channel_5ghz '48' option adhoc_ssid 'LiMe' option distance_2ghz '100' option distance_5ghz '1000' config net 'lm_hwd_openwrt_wan' option autogenerated 'false' list protocols 'ieee80211s' list protocols 'anygw' list protocols 'bmx6:0' list protocols 'wan' option linux_name 'wan
