What is this board??? Help!

@osbnet

No promises this will solve, but possibly it will help.

Theres a bit of info in this manual that is the closest thing to this router I can (rangely and similiar bios, ports, and such) our console cable is of course hidden on the side under the hood, as usb mini port.. I posted another suggestion regarding how to work from forcing failsafe and possibly from grub selection to get command interface. then refer to watchdog timer commands here possibly.
A watchdog timer is a piece of hardware that can be used to automatically detect system anomalies and
reset the processor in case there are any problems. Generally speaking, a watchdog timer is based on a
counter that counts down from an initial value to zero. The software selects the counter’s initial value and
periodically restarts it. Should the counter reach zero before the software restarts it, the software is
resumed to be malfunctioning and the processor’s reset signal is asserted. Thus, the processor will be
restarted as if a human operator had cycled the power.
To execute the utility: enter the number of seconds to start countdown before the system can be reset.
Press start to start the counter and stop to stop the counter.
wd_tst --swt xxx (Set Watchdog Timer 1-255 seconds)
wd_tst[*] --start (Start Watchdog Timer)
wd_tst --stop (Stop Watchdog Timer)

There are two ways to enable the bypass on the system:

1. The LAN bypass can be turned on or off in two system states, i.e., power on (Runtime Bypass) and
   power off (System Off Bypass). The following are the illustration of the possibilities of LAN bypass
   configuration with respect to both power-on and power-off states.
   Bypass settings in the
   BIOS
   System Status
   Runtime LAN Bypass for Module 1 Power off LAN Bypass for
   Module 1
   Enabled Disabled
   Power on Bypass Non-Bypass Enabled
   Power off Bypass Bypass
   Bypass settings in the
   BIOS
   System Status
   Runtime LAN Bypass for Module 1 Power off LAN Bypass for
   Module 1
   Enabled Disabled
   Power on Non-Bypass Non-Bypass Disabled
   Power off Non-Bypass Non-Bypass
2. A watchdog timer can be used to control the LAN Bypass function dynamically by programming. Lanner
   also provides sample code for bypass control with WDT via programming. For a reference utility that
   contains sample code for LAN Bypass function programming, please contact Lanner’s technical support.
   For thorough implementation information of Lanner Bypass and Watchdog functionalities, go to Lanner
   Support website at http://www.lannerinc.com/category/1202-network-appliances to download Lanner
   Bypass Implementation Manual.
   For a description of the physical LAN ports equipped with this function, refer to Front Panel in Chapter 1:

The Lanner FW-7551SE is similar to this only in that uses the same SoC. Importantly it does not use a switch.
I would not assume anything else there applies here.

I've obtained a 520-AC (5x0) - the boot serial output is very different from what's listed on here.
I'm waiting for an MPCIE to PCIE convertor to add a screen. The eBay mpcie gpu link given wont post to international destinations.
So far I can get it to attempt to boot other OS's from a USB, but so far no dice.
Trying to get the source OpenWRT built is very time consuming due to the age of versions of software installed no longer being available.
Thanks to everyone on here for the valuable information :-)

[dextaslab]

@bubbadestroy For the 520 (5X0) this adapter works in the spare MPCIE slot across from the wireless card https://www.ebay.com.au/itm/124831255241. I used an old nVidia PCIE graphics card with it. There is no BIOS setup as seen on other devices, but surprisingly there is IPXE by default. You can install most Linux distro's, as long as they only take about 60 seconds to boot the USB and install - then the watchdog timer kicks in and reboots :-(

Pfsense boots the installer and gets just far enough to wipe the internal storage and copy a few files across before it reboots.

[stephenw10]

I would try to install on something else then and swap the boot media into it. Then you can try top enable the watchdog tools in that image. Does it boot from USB? mSATA? No serial console?

[dextaslab]

@stephenw10 Yeah It boots from USB. As a test I edited the Debian installer grub options to include nmi_watchdog=0, but it made no difference, I'll try some other options and let you know.

[dextaslab]

@dextaslab Nailed it! Installed Ubuntu server (Im more familiar with Debian based distros) and added the following to the rc.local:

modprobe i2c-i801
modprobe i2c-smbus
modprobe iTCO-wdt

and "nmi_watchdog=0" was added as a boot switch.

As a test it boots and runs fine from a USB. Still working on the NICs, and the wireless joins fine for now. So I guess make sure those modules are added to the Pfsense installer it should at least install OK...

[bubbadestroy]

@dextaslab

This is awesome. Please do post update on progress, I'd love to see some PFSense (pun intended) made from this finding!

[bubbadestroy]

@kusagi

Seems progress made on this thread towards PFSENSE port! See posts at bottom i.e.:

Also He did solve the issue of WatchDog Timer on a velocloud edge variant

@bubbadestroy I've finally gotten the source Open-WRT mostly compiled and working. I'm pretty sure about 3 of the packages were non-starters - FRR for example. All the NIC's appear to be working and are available.

After wasting so much time trying to get PFSense compiled (and failing), I needed a win! The Open-WRT kernel it's running is pretty old and the source files for the NIC weren't directly compatible with FreeBSD 12.

If there is any info/files anyone would like let me know and I'll forward what I can. I'll upload the base Open-WRT USB image when I get time.

[dextaslab]

@bubbadestroy With OpenWRT installed I was able to get Qemu to then load OPNSense and pass network interfaces through to it. For more info: https://modlog.net/velocloud-520-to-opensource/

[dmsmartins]

@dextaslab you said that was able to make work with the 1gb sfp.. which sfp did you used?

[stephenw10]

@dextaslab said in What is this board??? Help!:

I was lucky enough to find and purchase a Velocloud 520 for $5AUD

Ha, nice!

[dextaslab]

@dmsmartins The SFP port I used was the top, the model number on the SFP is rubbed off as it was a very old, second hand eBay special. It was an 1GB RJ45 if that helps?

$5 for a couple of weeks entertainment, seems pretty good value too me :-)

@dextaslab Ok, good to hear that there is progress.
T.I.: Working here with EDGE 520-AC Unfortunately little success.
What does work, load the box with antiX fw, and then no problems with the watchdog. If halt after GRUB and before rebooting to antiX, the watchdog DOES come in, even with the extra opti "nmi_watchdog=0" in GRUB.
The intention is to run opensense, but this installation is interrupted by the annoying dog.

[adven]

@dextaslab
Hallo, from this google tranlation hi...
I am happy with the info on installing openwrt on the 520

But, There is an install file in /root/installer -p (after removing all partitions and setting a blank GPT) to copy the data from the USB to the internal 8GB storage.
Do you know why /tmp/mnt-inst is missing in /ets/fstab? And that's why /root/installer -p doesn't work?
Or am I doing something wrong.
greetings, Ad.

@dextaslab
Hallo,
One more question: still tried an installation with the dd command
“dd if=/dev/sda of=/dev/sdb”
this went well, but after a reboot no restart, and via a usb stick: Permission denied for sdb.
Any idee?
gr. Ad

[dextaslab]

@adven
If you add the following to the rc.local in AntiX it'll stop the watchdog:
modprobe i2c-i801
modprobe i2c-smbus
modprobe iTCO-wdt

I also had a few issues with /root/installer. from memory if it mounts the partitions directories once, then next time you run it, it fails - because their already mounted.

Did dd complete successfully? I found with one of the installs mine failed because the USB GPT was invalid.

[adven]

@dextaslab
Hallo.
Thanks for the quick response.
If i add the following to the rc.local in AntiX it'll , is the watchdog only gone when using antiX, or will this dog wake up again at some other fw.
Did dd complete successfully?: After a long time (1 hour or so) the operation stopped with no error message.
But the question was actually : Is /root/installer still present in your nicely made usb-image.
