We have been working on adding support for the Aztech HW550-3G router (Ralink RT3052F SoC ramips). It's a relatively new board with nice features: 384 MHz, 32 MB SDRAM, 8 MB flash, Ralink 2T2R Wireless N, 5 port 10/100 PHY + Gigabit MAC, USB 2.0 OTG, etc. It is similar to other RT3052 routers such as the Fonera 2.0n, Buffalo WHR-G300N, D-Link DIR-615 Rev D1, Belkin F5D8235v2 and ASUS RT-N13U... most of which already have initial board support in OpenWrt (with functional ethernet and wifi, USB is a WIP).
I have a patch for initial board support (which I submitted to the developer mailing list - see below). OpenWrt is running well with this patch, however we can't get the ethernet LAN/WAN to work. Wireless works fine.
I believe the problem is the embedded switch (ramips_esw) is not properly initialized and/or configured. The ethernet interface (eth0) appears to come up fine, but no connectivity with the switch and PHY LAN/WAN (see ifconfig below).
See this thread for the patch:
https://lists.openwrt.org/pipermail/ope … 09924.html
Any help, advice or suggestions is much appreciated.
Thanks,
Layne
