Topic: Support for Ralink RT3052 Router (Aztech HW550-3G) - No Ethernet Yet

The content of this topic has been archived on 5 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

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

I managed to get the ethernet working by reverting the ramips eth/esw drivers (target/linux/ramips/files/drivers/net) to SVN r24328 (svn up -r 24328).  I haven't investigated further to see what the real problem is yet.  I got the hint from the D-Link DIR-615 support post:

https://forum.openwrt.org/viewtopic.php … 81&p=4

Anyone know more about this issue with the ramips eth/esw drivers?

Thanks,
Layne

Here's a patch to fix the VLANs on the HW550-3G.  Without it, only 3 LAN ports will work and no WAN.  Apparently the VLANs are hard-coded or derived somehow in the ramips_esw driver... and the defaults are incorrect for the HW550-3G.  There is currently no support for swconfig in ramips.  This is just a hack for HW550-3G, but it will work until we get swconfig support.

 }

The patch in the following ticket fixes ethernet for the Aztech HW550-3G (i.e. instead of reverting to SVN r24328).  You will still need to hard-code the VLANs though, until there is swconfig support in ramips_esw.

Hi

Just wondering if anyone's got an img that we can use to get openwrt running on this board?

Have a Belkin F5D8235 which we want to install on.

Many thanks

Jenny

Hi, I just got this router and I'd like to test OpenWrt on it. Can you please provide me some hints on how to compile/install the OpenWrt on it? this is the first time I perform this operation and I don't know how to start or where to get informations...
Thank you in advance smile

how do you flash on hw550-3g? serial cable is mandatory?

The web interface will not accept the image, so you must flash manually from the CLI using sysupgrade or mtd.  Or you can use a serial cable and flash from u-boot.

Regards,
Layne

Need help here!!! Bricked the firmware while updating. What kind of cable needed to connect to serial?

Hi,

alright, being careless i have fried my bootloader and bricked the device - most probably for good. There's not really much to find about the de-bricking the unit, so if anybody has a clue on how to proceed with the JTAG'ing, especially software wise, kindly support. I guess I am not alone, reading previous posts.

I have taken a closeup of the board here: http://imageshack.us/photo/my-images/14/cimg2329dt.jpg/. In the lower right corner of the board is what appears to be the 14 pin JTAG interface. I will do some more researching, any hint, help or support would be awesome....

Thanks!!

Hi folks. Week ago I succesfully flashed my DIR-300 rev.B3 with custom firmware has been built from trunk. It works like a charm but except switch 'cause I missed kmod's for RT305x switch and now have only eth0, eth0.1, eth0.2 (swconfig dev eth0 help reports "Failed to connect to the switch"). Now I have only ssh access to the box, and it will take several hours to go into the place where device installed. Thus I tried to build appropriate modules (swconfig.ko, rtl8366_smi.ko, rtl8366s.ko, rtl8366rb.ko) and load them into running kernel but it took no effect. Does it mean hardware issue or m.b. switch only could be initialized while kernel boots up and reflashing proper image will help?
Thanks in advance.

There exists patch http://patchwork.openwrt.org/patch/2159/ for support of rt305x internal switch. And current vlan 1,2 are hardcoded in driver.

Thanks for the patch, will try it this weekend. I'd already thought to hardcode my vlans but it's a way of last resort I'd better like to avoid smile

That's what I need, it works. I reflashed it via emergency room 'cause after sysupgrade with new image I couldn't connect to the device.

The discussion might have continued from here.
