I was lucky enough to find and purchase a Velocloud 520 for $5AUD
Ha, nice!
$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?

@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.

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. -
@adven Have you tried assigning an IP address and opening the webpage? Because that looks about right to me. If you SSH into it you should also see a VeloCloud logo. From memory, after it's booted the VGA console had 3 lines of text on it.
-
@dextaslab
YES...
After a new install with only 1 warning about (/dev/sdb2 contains a ext4 file system)
was it possible to login to 10.0.1.1.
Also over SSH ok. Unfortunately in both cases a password was requested, which I do not know yet.
So far So good,
Thank you Kristian and others.
ps screenshots of latest install available for enthusiasts -
The default login for OpenWRT is root with an empty password.
-
@stephenw10
Yes,
I know, but in this case it's a complete Kristian img. (baked with openwrt in it). -
@adven
pw found,

@chrismontrose, I have Velocloud Edge500, & would like to install pfsense / esxi. I saw you can console connect with Velocloud. Would you please provide information on how to. I saw, a connector plugged . Is it Console serial port ?
thank very much.HKBebe7.

I'm having trouble with logging in to root on my 520 unit. Regardless of the login, it says "login incorrect". I've tried various combinations including "root, root" and "admin, velocloud" with no success. I was able to get into failsafe mode but was unable to change the root password using the passwd command. If anyone has any suggestions, let me know!

Thank you for keeping this alive!

Could someone share the root login info? I've tried lots of different combinations to get into the root user. I was able to get into safe mode which seemed to be a root user but no commands worked that I could think of. If anyone knows of a way to get root, let me know!

@osbnet we can not decrypt root password but you can change it via fail-safe mode of openwrt
Step #1: Disable watchdog
Method #1: Prefer link https://modlog.net/velocloud-520-to-opensource/
Method #2: Use Bios flash tool to flash old bios version at https://bitbucket.org/velocloud/openwrt/src/master/trunk/target/linux/x64/edge5x0/files/root/firmware/5×0/vc5x0-cb-01-bootorder.romStep #2: Connect PC with EDGE 520 via mini usb cable (speed 115200/8/1/none)
Step #3: Plug adapter to EDGE 520 and waiting device boot
Step #4: Press f to enter fail-safe mode
Step #5: Run two command below to change password
mount_root
echo -e "youpassword\nyoupassword" | passwd rootreboot device and try login with new password

@maitien2004 I've flashed the ROM you've mentioned and from what is appears in strings it looks good:
strings vc5x0-cb-01-bootorder.rom |grep watchdog -i
Disabling Watchdog timer...
CONFIG_USE_WATCHDOG_ON_BOOT=ystrings my-current.rom |grep watchdog -i
Found watchdog event..storing...
Raising Watchdog timer timeout to 3min...
CONFIG_USE_WATCHDOG_ON_BOOT=yI tested it with a Win11 Install USB - it complained about no UEFI, but that screen stayed up for longer than 3 minutes, so I'm calling it a win so far :-)
