What is this board??? Help!

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

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

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

@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.

@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/

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

I was lucky enough to find and purchase a Velocloud 520 for $5AUD
Ha, nice!
-
@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. -
@dextaslab
Hallo, from this google tranlation hi...
I am happy with the info on installing openwrt on the 520But, 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 -
@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-wdtI 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.
-
@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.

@dextaslab
Update about this fun project, because many VeloCloud 520 (5×0) boxes will be available in the near future. (support has been stopped).I am now following kristian's site at https://modlog.net/velocloud-520-to-opensource/ to continue with openwrt.
The installation with his self-made image did not work.
The cause turned out to be that the script wanted to install TO sda, but that is precisely the USB stick for me....
therefore booted with a fresh flashed usb stick, and from the root folder on sda gave the following command
./installer -d sdb -p
Now almost everything ok, 1 message that an ext4 (root labeled) was already present. Still went on.
and also a GPT PMBR size mismatch will be corrected by w(rite) meding, this one was easy to fix
according to https://superuser.com/questions/1352065/gpt-pmbr-size-mismatch-will-be-corrected-by-write (answer 1)I now have a nice busybox prompt, but unfortunately no openwrt logo.
To be continued.

The 2nd screenshot is after the reboot into the installed image I assume?
You have the boot log from that?

@stephenw10
Thanks for your comment.The 2nd screenshot is after the reboot into the installed image I assume?
==> yes indeed, after reboot or fresh start.You have the boot log from that?

That doesn't look good... and means a lot of puzzling for this layman when it comes to Linux.
